Question

A baseball player hits a ball toward the outfield. The height h of the ball in feet is modeled by h(t) = -16t2 + 22t + 3, where t is the time in seconds. In addition, the function d(t) = 85t models the horizontal distance d traveled by the ball. If no one catches the ball, how long will it stay in the air?

Answer 1

-16t2 + 22t + 3 = 0 i think

Answer 2

1.5

Answer 3

how did you get 1.5?

Answer 4

just solve the equation

Answer 5

I did, and i didn't 1.5

Answer 6

what u have

Answer 7

yes the roots are 1.5 and a negative root

Answer 8

im also suppose to find out what the horizontal distance that the ball travels before it hits the ground?
I got 127.5 can anyone tell me if im wrong?

Answer 9

yes but in this problem you don't need this

Answer 10

For this question, only the first equation is required

Answer 11

I know, but it was the problem under it. I was suppose to find it out also. But thank you (:

Answer 12

So you get the time = 1.5

d(1.5) = 85 * 1.5 = ?
