Answer:

1) Given the equation y = 35(0.57)^x

a) Does this equation represent growth or decay? ______Decay_________

b) What is the rate of growth or decay? _______43%________

1-0.57=0.43 100x0.43=43%

c) What is the initial value? _____35________

d) Evaluate for x = 3

y=(35)(0.57)^(3)

=(35)(0.185193)

Answer:

y = 2x - 5

Step-by-step explanation:

Hi,

y = 2x + b

Answer:

Difference in scores between his 7th and 8th quizzes = 22

Step-by-step explanation:

Given: Mean score for first 6 quizzes is 33 points. After his 7th quiz his mean score was 32 points. After the 8th quiz the mean was 34.

To find: difference in scores between his 7th and 8th quizzes

Solution:

Mean scores = Total points scored in quizzes ÷ Number of quizzes

So,

Total points scored in quizzes = Mean scores × Number of quizzes

As mean score for first 6 quizzes is 33 points,

Total points scored in 6 quizzes = 6 × 33 = 198

As mean score for first 7 quizzes is 32 points,

Total points scored in 7 quizzes = 7 × 32 = 224

So,

7th score = Total points scored in 7 quizzes - Total points scored in 6 quizzes

               = 224 - 198

               = 26

As mean score for first 8 quizzes is 34 points,

Total points scored in 8 quizzes = 8 × 34 = 272

So,

8th score = Total points scored in 8 quizzes - Total points scored in 7 quizzes

               = 272 - 224

               = 48

Therefore,

Difference in scores between his 7th and 8th quizzes = 48 - 26

                                                                                          = 22

Answer:

e=g(h-f) or e=gh - gf

Step-by-step explanation:

Answer:

e = hg - fg

Step-by-step explanation:

Given

[tex]\frac{e}{g}[/tex] + f = h ( multiply through by g to clear the fraction )

e + fg = hg ( subtract fg from both sides )

e = hg - fg

Answer:

1. -3/1

2.negative

3.$18

Step-by-step explanation:

since the graph is going down, it is negative, and look at the ending points on the x and y-axis. 18/6 is 3. so the slop is -3 :)

Answer:

1. -3

2. negative

3. $18

Step-by-step explanation:

1. slope is rise/run so...

-3/1=-3

2. because run was a change of 3 DOWN the y axis we and run is a change of 1 to the right on x axis we have a negative slope. -3

3. she borrowed $18. Vertical intercept means the point where our line crosses the vertical axis. (Vertical axis is Y axis.)

Step-by-step explanation:

[tex]\boxed{area \: of \: rectangle = length \times breadth}[/tex]

Area of shaded region

= Area of larger rectangle -area of smaller rectangle

Area of larger rectangle

= (3x -4)(2x +2)

= 3x(2x) +3x(2) -4(2x) -4(2) (Expand)

= 6x² +6x -8x -8

= 6x² -2x -8

Area of smaller rectangle

= (x -6)(x -3)

= x² -3x -6x +18 (Expand)

= x² -9x +18

Area of shaded region

= 6x² -2x -8 -(x² -9x +18)

= 6x² -2x -8 -x² +9x -18

= 5x² +7x -26

Decimal 3rd row: 0.75

Fraction 3rd row: 75%

Decimal last row: 0.15

Fraction last row: 15%

Answer:

75%, 0.75

Step-by-step explanation:

The answer is 75% because if you do the math it takes 6 15's to reach the requirement of the Fraction that is on the right. So that would make the decimal form be 0.75. If you find any fault in my answer let me know. Thanks. Have a good day!

Answer:

(s - 1)(s² + s + 1)

Step-by-step explanation:

s³ - 1 ← is a difference of cubes and factors in general as

a³ - b³ = (a - b)(a² + ab + b²) , then

s³ - 1

= s³ - 1³

= (s - 1)(s² + s + 1)

The required factorized form of the given expression is (s - 1)(s² + s + 1).

Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original. For example, the number 21 factors into primes as 3 × 7, and the polynomial x² − 9 factors as (x+3)(x-3).

We have been given that the expression below as

s³ - 1

We have to determine the factor of the given expression

As per the question, we have

s³ - 1

This is a difference between cubes and factors in general as

a³ - b³ = (a - b)(a² + ab + b²) , then

⇒ s³ - 1 = s³ - 1³

⇒ (s - 1)(s² + s + 1)

Thus, the required factorized form is (s - 1)(s² + s + 1).

Answer:

1. 40% 2. 1/10

Step-by-step explanation:

1. 8/20 * 100

800/20=40

2. 1/(3+1+4+2)

1/10

The value of x from the given figure is 40 degrees

Geometry is a way of relating lines and angles using theorems;

To get the value of x, we will use the expression based on the circle theorem:

80 = 1/2(200 - x)

Cross multiply

80 * 2  = (200 - x)

160 = 200 - x

x = 200 - 160

x = 40

Hence the value of x from the given figure is 40 degrees

Multiply 3 by 3

Therefore sum = 3*3 + 7/ 18

sum = 9+7/18

sum = 16/18

=> 8/9

Step-by-step explanation:

Answer:

y=5/3 is the only real solution

Step-by-step explanation:

Solve for y over the real numbers:

11 y^2 - 19 y - 10 = -4 y^2

Add 4 y^2 to both sides:

15 y^2 - 19 y - 10 = 0

The left hand side factors into a product with two terms:

(3 y - 5) (5 y + 2) = 0

Split into two equations:

3 y - 5 = 0 or 5 y + 2 = 0

Add 5 to both sides:

3 y = 5 or 5 y + 2 = 0

Divide both sides by 3:

y = 5/3 or 5 y + 2 = 0

Subtract 2 from both sides:

y = 5/3 or 5 y = -2

Divide both sides by 5:

Answer: |

| y = 5/3 or y = -2/5
