Lucille · Answer 1

Apply the concept of differential calculus. Tofind the maxima or minima if you are only given the equation, differentiate the equation and equate to zero.

h=-16t ² + 96t+4

dh/dt = 0 = - 32t + 96

Solving for t,

t = 3

Now, substitute t=3 to the original equation

h = - 16 (3) ² + 96 (3) + 4

h = 148 ft
