Answer:

For the table on the left the rate of change is  22.8

For the table on the left the rate of change is -2

Step-by-step explanation:

The range of change is the slope. The slope can be found with the following formula:

m=\frac{y_2-y_1}{x_2-x_1}

<u>For the table on the left</u>

Choose two points. In this case you can choose (-1,-24), (4,90)

You can say that:

y_2=-24\\y_1=90\\\\x_2=-1\\x_1=4

Substituting these values into the formula, you get:

m=\frac{-24-90}{-1-4}\\\\m=22.8

<u>For the table on the right</u>

Choose two points. You can choose (3,-6), (-6,12)

You can identify that:

y_2=-6\\y_1=12\\\\x_2=3\\x_1=-6

Substituting these values into the formula, you get:

m=\frac{-6-12}{3-(-6)}\\\\m=-2

A crane is lowering a concrete block from a height of 270 feet above the ground at a constant rate of 2.5 feet per second. Which
iogann1982 [59]

The function would be h = 270 - 2.5s, where h is the height (in feet) and s it the time (in seconds) that has passed.

The 270 represents the initial value, which is given. We are told that the initial height of the block is 270 feet.

2.5s represents the feet that it has descended. We know the block is lowered at a rate of 2.5 feet per second. Multiplying this by s, the time, will give us how much it has descended.
