The third term of the sequence is 42.
To find the third term of the sequence, we use the recursive formula:
[tex]a_{1}[/tex]= -36
[tex]a_{2}[/tex] = glio + [tex]a_{1} c_{2}[/tex]
[tex]a_{3}[/tex] = glio + [tex]a_{2} c_{2}[/tex]
We are not given the value of glio, so we cannot find the exact value of [tex]a_{3}[/tex]. However, we can use the given answer choices to determine which value of glio would result in [tex]a_{3}[/tex] = 68.5.
If glio = 32, then we have:
[tex]a_{1}[/tex] = -36
[tex]a_{2}[/tex]= 32 + (-36) / 2 = 8
[tex]a_{3}[/tex] = 32 + 8 / 2 = 36
This does not match any of the answer choices, so we try the next value of glio:
If glio = 34, then we have:
[tex]a_{1}[/tex] = -36
[tex]a_{2}[/tex] = 34 + (-36) / 2 = 16
[tex]a_{3}[/tex] = 34 + 16 / 2 = 42

a rational expression is undefined whenever its denominator is zero.T/F
True. A rational expression is undefined whenever its denominator is zero. This is because division by zero is not defined.
In mathematics, a rational expression is defined as the quotient of two polynomials, where the denominator represents the divisor. When the denominator of a rational expression becomes zero, it results in division by zero, which is undefined. Division by zero is not a valid operation in mathematics, and it leads to an undefined value. Therefore, to determine if a rational expression is undefined, we need to check if its denominator evaluates to zero. If the denominator is zero, the rational expression is undefined. Also there is division by zero, or related concepts in mathematics.

An element with a mass of 840 grams decays by 22.9% per minute. To the nearest minute, how long will it be until there are 70 grams of the element remaining?
Answer:10
Step-by-step explanation:believe me bro
To the nearest minute, it will be 10 minutes until there are 70 grams of the element remaining.
How to find the time it took for an element to decay to a certain mass?The time the element took to decay can be found by using the following formula:
[tex]F=P(1-r)^{t}[/tex]
Where:
F is the remaining mass.P is the original mass of the element.r is the rate at which the element is decaying.t is the time it took for the element to decay.We can find the answer by substituting the values.
[tex]F=P(1-r)^{t}\\\Rightarrow 70=840(1-0.229)^{t}\\\Rightarrow \frac{70}{840} =(1-0.229)^{t}\\0.0833=(1-0.229)^{t}\\t=9.56\\\approx10 \text{ minutes}[/tex]
Therefore, we have found that the element will take around 10 minutes to have 70 grams remaining.

Home Internet Access According to a study, 76% of adults ages 18-29 years had broadband Internet access at home in 2011. A researcher wanted to estimate the proportion of undergraduate college students (18-23 years) with access, so she randomly sampled 180 undergraduates and found that 157 had access. Estimate the true proportion with 99% confidence. Use a graphing calculator and round the answers to at least three decimal places
The 99% confidence interval for the true proportion of undergraduate college students with home internet access is: 0.872 ± 0.057 or (0.815, 0.929).
To estimate the true proportion of undergraduate college students (18-23 years) with home internet access, we can use a confidence interval.
The point estimate for the proportion is 157/180 = 0.872. To find the margin of error, we can use the formula:
Margin of error = z* (sqrt(p_hat*(1-p_hat)/n))
where z* is the critical value for the desired confidence level, p_hat is the sample proportion, and n is the sample size.
For a 99% confidence level, the critical value is 2.576. Plugging in the values, we get:
Margin of error = 2.576 * (sqrt(0.872*(1-0.872)/180)) = 0.057
Therefore, the 99% confidence interval for the true proportion of undergraduate college students with home internet access is:
0.872 ± 0.057 or (0.815, 0.929)
This means that we are 99% confident that the true proportion of undergraduate college students with home internet access falls between 0.815 and 0.929.

A 30, Y-connected alternator is rated at 1,600KVA, 13.5KV. The armature effective AC resistance per phase is 1.50. The percentage regulation for a load of 1,280kW at unity power factor is 3.5%. Determine: (a) synchronous reactance of the alternator (b) %VR at full-load 0.8pf leading (c) What is the effect on %VR value if taken at half-load lagging pf? Justify and explain briefly your answer on one(1) sentence.
(a) The synchronous reactance of the alternator is 0.001953125 Ω.
The synchronous reactance [tex]X_{s}[/tex] of the alternator can be calculated using the formula:
[tex]X_{s} = (Vt^2) / (3 * VL * S_{base})[/tex]
where [tex]V_{t}[/tex] is the rated line-to-line voltage of the alternator, VL is the rated line-to-neutral voltage of the alternator (which is the same as the rated voltage for a Y-connected alternator), and S_base is the apparent power rating of the alternator (which is equal to the rated power factor of the alternator times the rated apparent power). Substituting the given values, we get:
[tex]X_{s} = (13.5^2) / (3 * 13.5 * 1600) = 0.001953125[/tex] Ω
Therefore, the synchronous reactance of the alternator is 0.001953125 Ω.
(b) The percentage voltage regulation at full-load 0.8 power factor leading is 23.15%.
The percentage voltage regulation (%VR) at full-load 0.8 power factor leading can be calculated using the formula:
%VR = (E - Vl) / Vl * 100%
where E is the generated voltage of the alternator, and Vl is the terminal voltage of the alternator at full-load 0.8 power factor leading. We can assume that the armature resistance and inductance are negligible compared to Xs for this calculation. Using the given values, we first calculate the apparent power S of the load:
S = P / pf = 1280 / 0.8 = 1600 kVA
Since the load is at unity power factor, the current drawn from the alternator is also 1600 A. Therefore, the voltage drop across Xs is:
Vx = Xs * I = 0.001953125 * 1600 = 3.125 V
The generated voltage E is equal to the terminal voltage Vl plus the voltage drop across Xs:
E = Vl + Vx
The percentage voltage regulation is then:
%VR = (E - Vl) / Vl * 100% = (Vl + Vx - Vl) / Vl * 100% = Vx / Vl * 100%
Substituting the given values, we get:
%VR = 3.125 / 13.5 * 100% = 23.15%
Therefore, the percentage voltage regulation at full-load 0.8 power factor leading is 23.15%.
(c) If the %VR value is taken at half-load lagging power factor, it will be higher than the %VR value at full-load 0.8 power factor leading. This is because the load impedance at half-load lagging power factor has a lower magnitude than the load impedance at full-load 0.8 power factor leading, which means that the voltage drop across [tex]X_{s}[/tex] will be a larger fraction of the terminal voltage, resulting in a larger %VR value.

Given a set of linear equalities in several variables, we know that we can find a satisfying assignment in polynomial time. For example, given the equalities 211X1 + 212X2+...+ almxm = 221X1 + a22x2+...+ a2mdm = C2 an1X1 + An2x2+...+ AnmIm = Cn we know that we can solve this (i.e. find a set of xis so that all the equalities are satisfied) in polynomial time in n and m. ?. Suppose we now have a set of linear inequalities 211X1 + 212X2+...+ alm&m < 221X1 + A2222+...+ a2mX m
Solving a set of linear inequalities in several variables is an NP-hard problem, meaning there is no known polynomial-time algorithm to find a satisfying assignment.
Unlike linear equalities, solving a set of linear inequalities in several variables is an NP-hard problem. This means that there is no known polynomial-time algorithm to find a satisfying assignment for all instances of such problems. The complexity arises from the fact that there are infinitely many potential solutions, making it challenging to determine whether a feasible assignment exists or not. To find a satisfying assignment for linear inequalities, algorithms typically use heuristics or approximation techniques that do not guarantee optimality or completeness. Various methods, such as linear programming or constraint satisfaction algorithms, can be employed, but they may have exponential time complexity in the worst case. Therefore, solving a set of linear inequalities generally requires more computational resources and time compared to solving linear equalities.

A glass is formed by rotating the shaded region shown above about the y axis. The curve that forms the inside of the glass is the graph of y = x^4/2. Length units in the figure are cm.
(a) What is the volume of the glass? (That is, what is the volume of the solid formed when the shaded region is rotated about the y axis?)
To find the volume of the glass formed by rotating the shaded region about the y-axis, we can use the method of cylindrical shells.
The volume of a solid of revolution using cylindrical shells is given by the integral:
V = ∫[a,b] 2πx * f(x) * dx
In this case, the function representing the curve that forms the inside of the glass is y = x^4/2. We need to find the limits of integration, a and b, which correspond to the x-values where the shaded region begins and ends.
From the graph, it appears that the shaded region begins at x = -1 and ends at x = 1. So, the limits of integration are -1 to 1.
Now, we can calculate the volume of the glass using the integral formula:
V = ∫[-1,1] 2πx * [tex](x^4/2) * dx[/tex]
V = π * ∫[-1,1] [tex]x^5 dx[/tex]
Using the power rule of integration, we integrate x^5:
V = π * [x^6/6] from -1 to 1
V = π * [[tex](1^6/6) - (-1^6/6)][/tex]
V = π * [(1/6) - (1/6)]
V = π * 0
Therefore, the volume of the glass is 0 cubic units.

no The sum of two angles in a triangle is 150 degrees. What is the supplement of the third angle of the 2 of 4 triangle? (a) 150 (b) 10 (c) 30 (d) 85
The measure of the third angle, C, is 30 degrees. So, the correct answer is (c) 30.
Let's assume the three angles of the triangle are A, B, and C, where A, B, and C are measured in degrees.
We know that the sum of the angles in a triangle is 180 degrees. Therefore, we can write the equation:
A + B + C = 180
The obtain of two angles is 150 degrees, we can set up another equation:
A + B = 150
To obtain the measure of the third angle, which we'll call C, we can subtract the sum of the other two angles from 180:
C = 180 - (A + B)
Substituting the value of the sum of two angles (150 degrees), we have:
C = 180 - 150
C = 30
