The function C(x) = 25.50x + 50 models the total cost for a cleaning company to clean a house, where x is the number of hours it
vodomira [7]

Answer:

<em>The average rate of change is $25.5 per hour, option B.</em>

Step-by-step explanation:

<u>Average Rate of Change </u>

When we are explicitly given some function C(x), we sometimes need to know the rate of change of C when x goes from x=x_1 to x=x_2. It can be computed as the slope of a line .

\displaystyle m=\frac{C(x_2)-C(x_1)}{x_2-x_1}

The provided function is

C(x)=25.50x + 50

We are required to compute the average rate of change between the points

x_1=3\ ,\ x_2=9

Let's compute

C(3)=25.50(3) + 50=126.5

C(9)=25.50(9) + 50=279.5

\displaystyle m=\frac{279.5-126.5}{9-3}

\displaystyle m=\frac{153}{6}=25.5

The average rate of change is $25.5 per hour, option B.

The rectangle graphed has a length of 3 and a width of 2. How does the perimeter change if the width is increased by 4? A) The p
storchak [24]

Answer:

The answer to your question is the letter D.

Step-by-step explanation:

Data

First rectangle                       Second rectangle

length = 3                               length = 3

width = 2                                 width = 2 + 4 = 6

Process

1.- Calculate the Perimeter of the first rectangle

Perimeter = 2l + 2w

Perimeter = 2(3) + 2(2)

                 = 6 + 4

                 = 10

2.- Calculate the perimeter of the second rectangle

Perimeter = 2(3) + 2(6)

Perimeter = 6 + 12

Perimeter = 18

3.- Compare both perimeters

                Perimeter 1 is smaller than Perimeter 2 by 8 units
