Question

PLEASE HELP WILL FAN AND MEDAL
The equation h=-16t^2 + 32t +9 gives the height of a ball, h, in feet above the ground, at t seconds after the ball is thrown upward. How many seconds after the ball is thrown will it reach maximum height? What is its maximum height? Show all work.

Answer 1

Do you know derivatives?

Answer 2

Not really

Answer 3

. (-b/2a)= time
(-32/(2*-16))
=(-32/-32)
Time = 1 second
I know the time but I still need the height

Answer 4

Find h(1) and this will be your answer

Answer 5

how do I find h(1)?
