The height h (in feet) of a volleyball t seconds after it is hit can be modeled by h = -16t2 + 48t + 4. At what time does the volleyball reach its maximum height? What is the
maximum height reached by the volleyball?

14

step-by-step explanation:

14 x 3 = 42

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
