The height of a ball kicked in the air is modeled by the equation h(t) = -2t^2 +8t +24, where h is the height of the ball in fee

Setler79 [48]

Answer:

Step-by-step explanation:

The rate of change in any function is the slope of the line between 2 points. Our points are t = 2 and t = 5. But we know that the slope formula also involves the h's for each of those t's. We need to find them first. The slope formula is

$m=\frac{y_2-y_1}{x_2-x_1}$ , but for us it will look like this (fittted to our needs):

$m=\frac{h_2-h_1}{t_2-t_1}$ . So we need to find those h's.

when t = 2, plug in a 2 for t and solve for h.

Therefore, $h(2)=-2(2)^2+8(2)+24$ and

h(2) = 32 and in coordinate form, (2, 32).

When t = 5, plug in a 5 for t and solve for h.

Therefore, $h(5) =-2(5)^2+8(5)+24$ and

h(5) = 14 and in coordinate form, (5, 14). Now we can plug into our slope formula:

$m=\frac{14-32}{5-2}=\frac{-18}{3}=-6$ , choice B.

The rate of change is -6 which, in words, means that the ball fell 6 feet every 1 second it fell.
