Question

What is the height in feet do not round up the answer

Answer 1

72.25 ft

Explanation:

The function that models the height of the ball is

`h(t) = 68t - 16 {t}^(2)`

The maximum height occurs at:

`t = - (b)/(2a)`

`t = - (68)/(2 * - 16) = (68)/(32) = 2.125`

We substitute t=2.125 to get:

`h(2.125) = 68(2.125) - 16(2.125) ^(2)`

`h(2.125) = 72.25`

The maximum height is 72.25 feet
