Question

Does anyone know how to solve this! (30 points)

Answer 1

Explanation:

-16
`t^(2)` +50t + 3

they ask what is the height after exactly 3 seconds, so plug in the 3 for t

t(3) = -16*
`3^(2)` + 50*3 +3

t(3) = -144 +150 +3

t(3) = 9 feet, ( the ball has gone up and come back down most of the way )
