A ball is thrown vertically upward. After t seconds, its height h (in feet) is given by the function h(t) = 52t - 16t^2 . What i

Nata [24]

Answer: 42.25 feet

Step-by-step explanation:

We know that after "t" seconds, its height "h" in feet is given by this function:

$h(t) = 52t -16t^2$

The maximum height is the y-coordinate of the vertex of the parabola. Then, we can use the following formula to find the corresponding value of "t" (which is the x-coordinate of the vertex):

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

In this case:

$a=-16\\b=52$

Substituting values, we get :

$t=\frac{-52}{2(-16)}\\\\t=1.625$

Substituting this value into the function to find the maximum height the ball will reach, we get:

$h(1.625) = 52(1.625) -16(1.625)^2\\\\h(1.625) =42.25\ ft$
