Answers

Answer 1

Answer:

After t =  1.67 seconds, the rocket will have reached a height of 250 centimeters.

Step-by-step explanation:

Given

[tex]h = -90t^2 + 300t[/tex] --- correct expression

Required: When does height = 250 cm

To do this, we have:

[tex]h = 250[/tex]

This gives:

[tex]250 = -90t^2 + 300t[/tex]

Rewrite as:

[tex]90t^2 - 300t + 250 = 0[/tex]

Divide through by 10

[tex]9t^2 - 30t + 25 = 0[/tex]

Expand

[tex]9t^2 - 15t - 15t + 25 = 0[/tex]

Factorize:

[tex]3t(3t - 5) -5(3t - 5) = 0[/tex]

[tex](3t - 5)(3t - 5) = 0[/tex]

This gives:

[tex]3t - 5 = 0[/tex]

Solve for 3t

[tex]3t = 5[/tex]

Solve for t

[tex]t = \frac{5}{3}[/tex]

[tex]t = 1.67s[/tex]

Answers

The adjusted bank balance is $9,989 after considering unrecorded cash receipts, check printing charges, reconciling discrepancies in payments, outstanding checks, corrected check entries, NSF checks, and the credit memorandum for the customer's note collection.

Step 1: Initial Balances

The bank statement shows a balance per bank of $8,100, while the company's Cash account in the general ledger has a balance of $600 at November 30.

Step 2: Unrecorded Cash Receipts

The company's books recorded cash receipts of $6,070 on November 30, but this amount does not appear on the bank statement. We need to add this amount to the bank balance.

Bank Balance: $8,100 + $6,070 = $14,170.

Step 3: Debit Memorandum for Check Printing Charges

The bank statement shows a debit memorandum of $50 for check printing charges. We need to deduct this amount from the bank balance.

Bank Balance: $14,170 - $50 = $14,120.

Step 4: Discrepancy in Check to Carla Vista Company

Check No. 119, payable to Carla Vista Company, was recorded in the cash payments journal and cleared the bank for $258. However, a review of the accounts payable subsidiary ledger shows a $27 credit balance in Carla Vista Company's account, and the payment should have been for $285. We need to adjust for this discrepancy.

Bank Balance: $14,120 + $285 - $258 = $14,147.

Step 5: Outstanding Checks

The total amount of checks still outstanding at November 30 is $6,020. We need to deduct this amount from the bank balance.

Bank Balance: $14,147 - $6,020 = $8,127.

Step 6: Corrected Check No. 198

Check No. 198 was correctly written and paid by the bank for $406. However, the cash payment journal reflects an entry for check No. 138 as a debit to accounts payable and a credit to cash in the bank for $460. This entry needs to be adjusted.

Bank Balance: $8,127 - ($460 - $406) = $8,073.

Step 7: NSF Check

The bank returned an NSF check from a customer for $630. We need to deduct this amount from the bank balance.

Bank Balance: $8,073 - $630 = $7,443.

Step 8: Credit Memorandum for Customer's Note Collection

The bank included a credit memorandum for $2,680, representing the collection of a customer's note by the bank for the company. The principal amount of the note was $2,546, and the interest was $134. Since interest has not been accrued, we need to add the principal amount to the bank balance.

Bank Balance: $7,443 + $2,546 = $9,989.

Therefore, the adjusted bank balance is $9,989.

Find the general solution to the equation:

the general solution to the differential equation [tex]x dy/dx = 3(y+x^2)[/tex] can be obtained  [tex]|y + x| = K .|x|^3[/tex], where K is a positive constant. typographical error is considered here since there are 2 equal signs.

The given differential equation is [tex]x(dy/dx) = 3(y + x^2) = sin(x)/x.[/tex]  Notice that the equation contains two equal signs, which seems to be a typographical error. Assuming it is intended to be a single equation, we will consider it as [tex]x(dy/dx) = 3(y + x^2)[/tex].

To solve this equation, we start by rearranging it:

[tex]x(dy/dx) - 3(y + x^2) = 0[/tex].

Next, we can further simplify by dividing through by x:

[tex](dy/dx) - 3(y/x + x) = 0.[/tex]

Now, we have a separable differential equation. We can rewrite it as:

(dy/(y + x)) - 3(dx/x) = 0.

Separating the variables, we get:

[tex]dy/(y + x) = 3dx/x.[/tex]

Integrating both sides with respect to their respective variables, we obtain:

[tex]\[ \int_{}^{} 1(/y+x) \,dy \] =[/tex][tex]\[ \int_{}^{} 3/x \,dx \][/tex]

The integral on the left side can be evaluated as [tex]ln|y + x|[/tex], while the integral on the right side is [tex]3ln|x| + C,[/tex] where C is the constant of integration.

Therefore, we have:

[tex]ln|y + x| = 3ln|x| + C[/tex].

To simplify further, we can use logarithmic properties to rewrite the equation as:

[tex]ln|y + x| = ln|x|^3 + C[/tex].

Taking the exponential of both sides, we get:

|[tex]y + x| = e^{(ln|x|^3 + C)[/tex].

Simplifying the expression, we have:

[tex]|y + x| = e^{(ln|x|^3)}.e^C[/tex].

Since e^C is a positive constant, we can rewrite it as K, where K > 0.

a) Let f : R → R by f(x) = ax + b, where a + 0 and b are constants. Show that f is bijective and hence f is invertible, and find f-1. b) Let R be the relation with ordered pairs (Aaron, 25), (Brenda, 24), (Caleb 23), (Desire, 22), (Edwin 22), (Felicia 24). Here each pair consists of a graduate student and the student's age. Specify a function determined by this relation.

Answers

a) The inverse function f^(-1)(y) is given by f^(-1)(y) = (y - b)/a.

b) The function f determined by the relation R maps each student's name to their respective age.

a) To show that the function f(x) = ax + b is bijective and invertible, we need to prove both injectivity (one-to-one) and surjectivity (onto).

Injectivity:

Let x1 and x2 be arbitrary elements in the domain R such that f(x1) = f(x2). We need to show that x1 = x2.

Using the definition of f(x), we have ax1 + b = ax2 + b.

By subtracting b from both sides and then dividing by a, we get ax1 = ax2.

Since a ≠ 0, we can divide both sides by a to obtain x1 = x2.

Thus, the function f is injective.

Surjectivity:

Let y be an arbitrary element in the codomain R. We need to show that there exists an element x in the domain R such that f(x) = y.

Given f(x) = ax + b, we solve for x: x = (y - b)/a.

Since a ≠ 0, there exists an element x in R such that f(x) = y for any given y in R.

Thus, the function f is surjective.

Since the function f is both injective and surjective, it is bijective. Therefore, it has an inverse function.

To find the inverse function f^(-1), we can express x in terms of y:

x = (y - b)/a.

Now, interchange x and y:

y = (x - b)/a.

Therefore, the inverse function f^(-1)(y) is given by f^(-1)(y) = (y - b)/a.

b) The relation R with ordered pairs (Aaron, 25), (Brenda, 24), (Caleb, 23), (Desire, 22), (Edwin, 22), (Felicia, 24) can be represented as a function by considering the student's name as the input and the age as the output.

Let's define the function:

f(name) = age.

Using the given relation R, the function f determined by this relation is:

f(Aaron) = 25,

f(Brenda) = 24,

f(Caleb) = 23,

f(Desire) = 22,

f(Edwin) = 22,

f(Felicia) = 24.

So, the function f determined by the relation R maps each student's name to their respective age.

Answers

The probability of any newborn baby being a boy is 1/2, and since all births are assumed to be independent, we can use the probability of a girl (1 - 1/2 = 1/2) to calculate the probability of none of the five children being boys.

The probability of having a girl for each child is 1/2. Since all births are independent, the probability of having all five children be girls is calculated by multiplying the individual probabilities:

(1/2) * (1/2) * (1/2) * (1/2) * (1/2) = (1/2)^5 = 1/32

The base of S is the region enclosed by the parabola y=1-x² and the x-axis. Cross-sections perpendicular to the y-axis are squares.

Answers

The volume of the solid S is 4 cubic units. The area of the square cross-section at height y is (2√(1 - y))² = 4(1 - y).

To find the volume of the solid S, we need to integrate the areas of the square cross-sections perpendicular to the y-axis over the interval that represents the base of S.

The given information tells us that the base of S is the region enclosed by the parabola y = 1 - x² and the x-axis. To determine the limits of integration, we need to find the x-values where the parabola intersects the x-axis.

Setting y = 0 in the equation y = 1 - x², we get:

0 = 1 - x²

x² = 1

x = ±1

So, the base of S extends from x = -1 to x = 1.

Now, let's consider a generic cross-section at a height y perpendicular to the y-axis. Since the cross-section is a square, its area is equal to the square of its side length.

The side length of the square cross-section at height y is given by the difference between the y-value of the parabola and the x-axis at that height. From the equation y = 1 - x², we can solve for x:

x² = 1 - y

x = ±√(1 - y)

Therefore, the area of the square cross-section at height y is (2√(1 - y))² = 4(1 - y).

To find the volume of the solid S, we integrate the areas of these square cross-sections over the interval of the base:

V = ∫[from -1 to 1] 4(1 - y) dy

Evaluating this integral, we get:

V = 4∫[from -1 to 1] (1 - y) dy

V = 4[y - (y²/2)] | from -1 to 1

V = 4[(1 - (1²/2)) - (-1 - ((-1)²/2))]

V = 4[(1 - 1/2) - (-1 - 1/2)]

V = 4[1/2 + 1/2]

V = 4

Answers

(a) The quotient is 16 and remainder is 4. (b) The quotient is (-28) and remainder is (-4).

The quotient and remainder when a is divided by d of the following pairs of integers are:

(a) Quotient is the result of division between two integers. It is defined as the nearest integer less than or equal to the exact value of the fraction. We can find the quotient by dividing the dividend by the divisor.

So, the quotient for a = 100 and d = 6 is given as follows:quotient = a ÷ d  = 100 ÷ 6= 16Therefore, the quotient is 16.

Remainder is the leftover part of a division. It is the integer that remains after the division operation.

The remainder can be found by taking the dividend and subtracting it by the product of the quotient and divisor.

So, the remainder for a = 100 and d = 6 is given as follows:remainder = a - (quotient × d)remainder = 100 - (16 × 6)= 4.Therefore, the remainder is 4.

(b) The quotient and remainder for this pair of integers can be calculated by using the above method.

quotient = a ÷ d = -200 ÷ 7Quotient is -28. The nearest integer less than or equal to -28 is -28.

remainder = a - (quotient × d)remainder = -200 - (-28 × 7)= -200 + 196= -4Therefore, the remainder is -4.

Standard deviation of hourly wages:Standard deviation is a measure of the amount of variation or dispersion of a set of values. It is calculated by taking the square root of the variance. Variance is calculated by taking the average of the squared differences of each value from the mean. Here, we will use the formula of sample standard deviation.S = √[Σ(xi - x)² / (n - 1)]Where,S is the standard deviation.x is the mean hourly wage.n is the number of observations.Σ is the sum of.xi is the ith observation.Substituting the values in the above formula:S = √[(27 - 18)² + (25 - 18)² + (20 - 18)² + (10 - 18)² + (12 - 18)² + (14 - 18)² + (17 - 18)² + (19 - 18)² / 7]S = √[198 / 7]S = √28.29Therefore, the standard deviation is approximately $5.31.

25th percentile of hourly wages:The 25th percentile is the value below which 25% of the observations fall. Here, we will calculate the 25th percentile by arranging the hourly wages in ascending order and then finding the value that corresponds to the 25th percentile. Therefore, the values are:10, 12, 14, 17, 19, 20, 25, 27Total observations = 8As we need the value for the 25th percentile, we need to find out which observation is at that point.25% of 8 = 0.25 × 8 = 2As the value 2 is a whole number, we can say that the 25th percentile falls between the 2nd and 3rd observations.Therefore, the 25th percentile can be approximated as the average of the 2nd and 3rd observations.(12 + 14) / 2 = 13Therefore, the 25th percentile is $13.

We can predict that an 11-year-old child will have approximately 4 cavities.

The method of correlational research is used to examine the relationship between variables. When two variables are compared to determine if they are related, correlational research is employed. One variable is plotted on the x-axis and the other is plotted on the y-axis. The scatter plot is utilized to see whether a relationship exists between the two variables.In this question, we will be using correlational research to determine whether there is a relationship between the age of a child and the number of cavities he or she has. The given data are:

| Age of child | No. of cavities |
| ------------ | --------------- |
| 6            | 2               |
| 8            | 1               |

| 12           | 6               |
| 14           | 5               |
We will begin by drawing a scatter plot of the data to see whether a relationship exists between the two variables. As seen in the scatter plot above, there appears to be a positive relationship between age and the number of cavities. This means that as age increases, the number of cavities appears to increase as well. The correlation coefficient between the two variables is r = 0.8426. A correlation of +1 indicates a perfect positive correlation, whereas a correlation coefficient of -1 indicates a perfect negative correlation. A correlation coefficient of 0 indicates that there is no correlation between the two variables. As a result, a correlation coefficient of 0.8426 indicates that there is a strong positive correlation between the two variables.Now that we have established that there is a relationship between age and the number of cavities, we can predict the number of cavities for an 11-year-old child.

What is the equation that models blood alcohol percent as a function of x, where x is the number of drinks?

Answers

a) The rate of change in blood alcohol percent is: 0.03%

b) The equation that models blood alcohol percent as a function of x is:

y = 0.03x + 0.04

How to solve the Linear Model?

a) We are told that the average rate of change in blood alcohol percent with respect to the number of drinks is a constant.

The constant is also referred to as the slope and can be gotten from the formula:

Constant = (y₂ - y₁)/(x₂ - x₁)

Taking two coordinates as (5, 0.19) and (6, 0.22), we have:

Constant = (0.22 - 0.19)/(6 - 5)

Constant = 0.03

b) If we assume that x is number of drinks and y is blood alcohol percent, then we say that using the equation format y = kx + b, that:

k = 0.03

Using the first coordinate gives:

0.19 = 0.03(5) + b

b = 0.19 - 0.15

b = 0.04

Thus, the linear model is:

y = 0.03x + 0.04

similar to 4.1.23 in rogawski/adams. use the linear approximation to estimate δf=e−0.3−1. what is f(x)? f(x)=

Answers

To estimate δf = [tex]e^(-0.3)[/tex] - 1 using linear approximation, we can start by finding the tangent line to the curve of the function f(x) at the given point x = -0.3. This can be done by calculating the derivative of f(x) and evaluating it at x = -0.3.

Let's assume the function f(x) is given by f(x) = [tex]e^x[/tex]. Taking the derivative of f(x) with respect to x, we have f'(x) = [tex]e^x.[/tex]

Now, we can evaluate the derivative at x = -0.3:

f'(-0.3) = e^(-0.3).

This gives us the slope of the tangent line at x = -0.3. Next, we use the point-slope form of a line to find the equation of the tangent line:

y - f(-0.3) = f'(-0.3) * (x - (-0.3)).

Since f(-0.3) = [tex]e^(-0.3)[/tex], we have:

y - e^(-0.3) = e^(-0.3) * (x + 0.3).

This equation represents the linear approximation of f(x) near x = -0.3. To estimate δf = e^(-0.3) - 1, we can evaluate the above equation at x = -0.3:

[tex]f(x) = e^(-0.3) * (x + 0.3) + e^(-0.3).[/tex]

Hence, [tex]f(x) = e^(-0.3) * x + e^(-0.3) * 0.3 + e^(-0.3).[/tex]

[tex]f(x) = e^(-0.3) * x + 2 * e^(-0.3).[/tex]

Approximate the following binomial probabilities by the use of normal approximation. 80% of customers of a bank keep a minimum balance of $500 in their checking accounts. What is the probability that in a random sample of 100 customers a. exactly 80 keep the minimum balance of $500? b. 75 or more keep the minimum balance of $500?

Answers

a. The probability of exactly 80 customers keeping the minimum balance of $500 can be approximated using the normal approximation to the binomial distribution.  b. The probability of 75 or more customers keeping the minimum balance of $500 can also be approximated using the normal approximation to the binomial distribution.

a. To approximate the probability of exactly 80 customers keeping the minimum balance of $500 in a random sample of 100 customers, we can use the normal approximation to the binomial distribution. The mean (μ) is equal to the product of the sample size (n) and the probability of success (p), which is 100 * 0.8 = 80. The standard deviation (σ) is the square root of n * p * (1 - p), which is sqrt(100 * 0.8 * 0.2) ≈ 4. In this case, we can use a continuity correction since we are approximating a discrete probability with a continuous distribution. Thus, we can calculate the probability using the normal distribution with a mean of 80 and a standard deviation of 4.

b. To approximate the probability of 75 or more customers keeping the minimum balance of $500, we need to calculate the cumulative probability of 75 or fewer customers not keeping the minimum balance. Using the same normal approximation, we can calculate the z-score for 75 customers and use the cumulative distribution function of the normal distribution to find the probability. The z-score is given by (75 - 80) / 4 ≈ -1.25. We can then use the normal distribution table or software to find the cumulative probability associated with the z-score of -1.25 and subtract it from 1 to obtain the probability of 75 or more customers keeping the minimum balance.

A sample of size n = 21 was randomly selected from a normally distributed population. The data legend is as follows:
X = 234, s = 35, n = 21
It is hypothesized that the population has a variance of σ^² = 40 and a mean of μ = 220. Does the random sample support this hypothesis? Choose your own parameters if any is missing.

Answers

Based on the hypothesis tests, the random sample does not support the hypothesis that the population has a variance of σ^2 = 40 and a mean of μ = 220.

To determine if the random sample supports the hypothesis that the population has a variance of σ^2 = 40 and a mean of μ = 220, we can conduct a hypothesis test.

The null hypothesis (H0) is that the population has a variance of σ^2 = 40 and a mean of μ = 220.

The alternative hypothesis (HA) is that the population does not have a variance of σ^2 = 40 and a mean of μ = 220.

To test this hypothesis, we can use the chi-square test for variance and the t-test for the mean. Since we are given the sample standard deviation (s = 35) and the sample mean (X = 234), we can calculate the test statistics.

For the variance test, we calculate the chi-square statistic as:

chi-square = (n - 1) * s^2 / σ^2 = (21 - 1) * 35^2 / 40 = 357.75.

For the mean test, we calculate the t-statistic as:

t = (X - μ) / (s / sqrt(n)) = (234 - 220) / (35 / sqrt(21)) ≈ 2.545.

To determine if the sample supports the hypothesis, we compare the test statistics to their respective critical values based on the significance level (α) chosen. Since no significance level is given, let's assume α = 0.05.

For the variance test, we compare the chi-square statistic to the critical chi-square value with (n - 1) degrees of freedom.

For α = 0.05 and (n - 1) = 20 degrees of freedom, the critical chi-square value is approximately 31.41.

Since 357.75 is greater than 31.41, we reject the null hypothesis.

For the mean test, we compare the t-statistic to the critical t-value with (n - 1) degrees of freedom.

For α = 0.05 and (n - 1) = 20 degrees of freedom, the critical t-value is approximately ±2.086.

Since 2.545 is greater than 2.086, we reject the null hypothesis.

MRS between A and B: -2.5, B and C: -0.8, C and D: -0.375, D and E: -0.2. Negative values indicate the diminishing marginal rate of substitution.

The Marginal Rate of Substitution (MRS) measures the rate at which a consumer is willing to trade one commodity for another while keeping the same level of satisfaction. To calculate the MRS between X and Y, we can use the formula: MRS = (Change in quantity of X) / (Change in quantity of Y).

Using the given combinations:

MRS between A and B: (25 - 20) / (3 - 5) = 5 / -2 = -2.5

MRS between B and C: (20 - 16) / (5 - 10) = 4 / -5 = -0.8

MRS between C and D: (16 - 13) / (10 - 18) = 3 / -8 = -0.375

MRS between D and E: (13 - 11) / (18 - 28) = 2 / -10 = -0.2

After considering the given data we conclude that as x reaches 2, the function [tex]f(x) = x^3 - 2x^2 + 4/(x-2)[/tex]has limit 4.

To express that as x → 2, the function [tex]f(x) = x^3 - 2x^2 + 4/(x-2)[/tex]has limit 4, we can factor the numerator as [tex](x-2)^2(x+2)[/tex] and apply simplification of the function as follows:
[tex]f(x) = [(x-2)^2(x+2)] / (x-2)[/tex]
[tex]f(x) = (x-2)(x-2)(x+2) / (x-2)[/tex]
[tex]f(x) = (x-2)(x+2)[/tex]
Since the denominator of the function is (x-2), which approaches 0 as x approaches 2, we cannot simply substitute x=2 into the simplified function.
Instead, we can apply the factored form of the function to cancel out the common factor of (x-2) and evaluate the limit as x approaches 2:
[tex]lim(x- > 2) f(x) = lim(x- > 2) (x-2)(x+2) / (x-2)[/tex]
[tex]lim(x- > 2) f(x) = lim(x- > 2) (x+2)[/tex]

the Laplace transforms are:
(a) L{tcos(bt)} = -2b^2 / (s^2 + b^2)^2.
(b) L{t^2cos(bt)} = 6b^2s^2 / (s^2 + b^2)^3.

To determine the Laplace transforms of the given expressions, we can use the formula provided: {tnf(t)}(s) = (-1)^n * d^n/ds^n [d^n/ds^n(f * f)(s)].

(a) For L{tcos(bt)}, we have n = 1, f(t) = cos(bt). Plugging these values into the formula, we get:

{tcos(bt)}(s) = (-1)^1 * d/ds [d/ds(cos(bt) * cos(bt))(s)].

Differentiating twice, we obtain:

{tcos(bt)}(s) = -d^2/ds^2 [cos^2(bt)] = -2b^2 / (s^2 + b^2)^2.

(b) For L{t^2cos(bt)}, we have n = 2, f(t) = cos(bt). Using the formula, we have:

{t^2cos(bt)}(s) = (-1)^2 * d^2/ds^2 [d^2/ds^2(cos(bt) * cos(bt))(s)].

Differentiating twice, we get:

{t^2cos(bt)}(s) = d^4/ds^4 [cos^2(bt)] = 6b^2s^2 / (s^2 + b^2)^3.

Therefore, the Laplace transforms are:

How to Evaluate Integral Using Limit Notation

We can recast the integral as a definite integral with appropriate limits of integration in order to evaluate the integral ex dx using the proper limit notation.

With respect to x, the indefinite integral of ex is equal to ex + C, where C is the integration constant.

We must establish the bounds of integration in order to find the definite integral. We can indicate the limitations of integration using a general notation because no precise constraints are given.

Let's evaluate the integral using limit notation:

∫[a to b] e^x dx

Here, [a to b] represents the limits of integration from a to b.

By subtracting the antiderivative of the function evaluated at the upper limit from the antiderivative of the function evaluated at the lower limit, we may calculate the definite integral using the calculus fundamental theorem:

∫[a to b] e^x dx = [e^x] from a to b = e^b - e^a

In this case, since the limits of integration are not specified, we cannot provide a numerical value for the integral.

Justin flips a fair coin 8 times. What is the that he gets an odd amount of probability heads?

Answers

The probability that Justin gets an odd amount of heads when flipping a fair coin 8 times is 1/2 or 50%.

To calculate the probability of getting an odd number of heads when flipping a fair coin 8 times, we can use combinatorics.

The total number of possible outcomes when flipping a coin 8 times is [tex]2^8[/tex] = 256, as each flip has 2 possible outcomes (heads or tails).

To determine the number of outcomes that result in an odd number of heads, we need to consider the different combinations of heads and tails that would yield an odd sum. An odd number can only be obtained by having an odd number of heads (1, 3, 5, 7) because the number of coin flips is even.

We can break it down as follows:

Number of outcomes with 1 head: C(8,1) = 8

Number of outcomes with 3 heads: C(8,3) = 56

Number of outcomes with 5 heads: C(8,5) = 56

Number of outcomes with 7 heads: C(8,7) = 8

Summing up these possibilities, we get:

8 + 56 + 56 + 8 = 128

Therefore, there are 128 outcomes that result in an odd number of heads out of the total 256 possible outcomes.

The probability of getting an odd amount of heads is given by:

Probability = Number of outcomes with odd heads / Total number of outcomes

Probability = 128 / 256

Answers

(a) i. The derivative of y = (x^2 + 1) arctan x - x is: y' = ((2x * arctan x) / (1 + x^2)) - 1.

To find the derivative of y = (x^2 + 1) arctan x - x, we will use the sum and product rules of differentiation.

First, let's find the derivative of (x^2 + 1) arctan x using the product rule:

u = (x^2 + 1) and v = arctan x

u' = 2x and v' = 1 / (1 + x^2)

Using the product rule formula (uv' + vu'), we get:

((x^2 + 1) * (1 / (1 + x^2))) + ((2x * arctan x))

(2x * arctan x) / (1 + x^2)

Next, let's find the derivative of -x using the power rule:

y' = ((2x * arctan x) / (1 + x^2)) - 1

ii. The derivative of y = cosh(2x log x) is: y' = 2x sinh(2 log x) + 2 sinh(2 log x).

By using the chain rule. Let's first rewrite cosh(2x log x) as cosh(u), where u = 2x log x.

The derivative of cosh(u) is sinh(u), and the derivative of u with respect to x is:

u' = 2(log(x)) + 2x(1/x)

= 2(log(x)) + 2

Using the chain rule formula (dy/dx = dy/du * du/dx), we can find the derivative of y with respect to x:

y' = sinh(2x log x) * (2(log(x)) + 2)

y' = 2x sinh(2 log x) + 2 sinh(2 log x)

(b) Using logarithmic differentiation, we have found that: y' = x * 7 * cosh^3(r) * ((1/x) + (tanh(r)) * (dr/dx)).

To find y if y = x * 7 * cosh^3(r), we will use logarithmic differentiation.

First, take the natural logarithm of both sides of the equation:

ln(y) = ln(x * 7 * cosh^3(r))

ln(y) = ln(x) + ln(7) + 3ln(cosh(r))

Next, we will differentiate both sides of the equation with respect to x using the chain rule:

d/dx(ln(y)) = d/dx(ln(x) + ln(7) + 3ln(cosh(r)))

On the left side of the equation, we can use the chain rule and the fact that dy/dx = y': d/dx(ln(y)) = (1/y) * y'

On the right side of the equation, we can use the sum and constant multiple rules of differentiation:

d/dx(ln(x)) = 1/x

d/dx(ln(7)) = 0

d/dx(ln(cosh(r))) = (tanh(r)) * (dr/dx)

(1/y) * y' = (1/x) + (tanh(r)) * (dr/dx)

y' = y * ((1/x) + (tanh(r)) * (dr/dx))

Substituting y = x * 7 * cosh^3(r), we get:

y' = x * 7 * cosh^3(r) * ((1/x) + (tanh(r)) * (dr/dx))

The population grows exponentially, so

P(t) = P₀ e r t,

where P₀ is the initial population and r is the annual growth rate. We are given P₀ = 10, so the formula becomes:

P(t) = 10e^rt

We are given that the population grows by 7% each year.

Therefore r = 7/100 = 0.07.

Substituting this value into the formula:

P(t) = 10e^0.07t

Evaluating P(8):

P(8) = 10e^0.07(8)≈ 20.21

Therefore, the population after 8 years is approximately 20.21 (rounded to two decimal places).Thus, we can conclude that the explicit formula for population growth is P(t) = 10e^0.07t and the population after 8 years is approximately 20.21 (rounded to two decimal places).

Define a sequence a,, so that ao = 2, a₁ = 3, and a₁ = 6an-1-8an-2. (a) Write a generating function for (a) in the form of a rational function. That is, find a rational function f such that f(x) = 0 anx".

Answers

The generating function for the sequence a is given by the rational function f(x) = (a₀ + (6a₀ - a₁)x) / (1 - 6x + 8x²), where f(x) = ∑anxⁿ.

The given sequence a is defined recursively as ao = 2, a₁ = 3, and an = 6an-1 - 8an-2. To find a generating function for the sequence, we can represent the sequence as a power series and express it in the form of a rational function.

To find a generating function for the sequence a, we can consider the terms of the sequence as coefficients of a power series. Let's define A(x) as the generating function for the sequence a, where A(x) = a₀ + a₁x + a₂x² + a₃x³ + ...

Using the given recursive relation an = 6an-1 - 8an-2, we can express it in terms of the generating function A(x). Multiplying the equation by xn and summing over n, we get:

A(x) - a₀ - a₁x = 6(xA(x) - a₀) - 8(x²A(x) - a₀)

Simplifying the equation, we have:

A(x) - a₀ - a₁x = 6xA(x) - 6a₀ - 8x²A(x) + 8a₀

Rearranging the terms, we get:

A(x) - 6xA(x) + 8x²A(x) = a₀ + (6a₀ - a₁)x

Factoring out A(x), we have:

A(x)(1 - 6x + 8x²) = a₀ + (6a₀ - a₁)x

Finally, dividing both sides by (1 - 6x + 8x²), we obtain:

A(x) = (a₀ + (6a₀ - a₁)x) / (1 - 6x + 8x²)

Therefore, the generating function for the sequence a is given by the rational function f(x) = (a₀ + (6a₀ - a₁)x) / (1 - 6x + 8x²), where f(x) = ∑anxⁿ.

A 45g golf ball is hit off a tee with an initial speed of 65 m/s. The force applied can be modeled by the equation: F = C(t - 2) Where C is a constant, and t is the time after the hit in seconds. The duration the force is applied is 0.5 ms. Determine the value of the constant C in Si base units.

Answers

After considering all the given data we conclude that the value of the constant c is 5850 N.

To evaluate the value of the constant C in Si base units, we need to apply the equation [tex]F = C(t - 2)[/tex]and the given information that the duration the force is applied is 0.5 ms.
It is known to us that the force applied is what causes the golf ball to accelerate, so we can apply the equation for acceleration:
[tex]a = F/m[/tex]
Here,
m = mass of the golf ball.
We can restructure the equation
F = ma to find out C:
[tex]F = C(t - 2)[/tex]
[tex]ma = C(t - 2)[/tex]
[tex]C = ma/(t - 2)[/tex]
Staging the given values, we get:
[tex]C = (0.045 kg)(65 m/s)/(0.0005 s - 2 s)[/tex]
Applying simplification , we get:
C = 5850 N
Hence, the value of the constant C in Si base units is 5850 N.
