Question

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

Answer 1

Answer:

72.25 ft

Step-by-step explanation:

The function that models the height of the ball is

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

The maximum height occurs at:

$t = - \frac{b}{2a}$

$t = - \frac{68}{2 \times - 16} = \frac{68}{32} = 2.125$

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
