Question

An onject is.launched from platform. Its height (in meters) x seconds after the launch is modeled by h(x) =-5(x+1)(×-9) How many seconds after launch will the object hit the ground

Answer 1

the object will hit the ground at x=9

Explanation:

h(x) =-5(x+1)(×-9)

0 =5(x+1)(×-9)

using the zero product property

the x intercepts or zeros of the equation are x+1 =0 and x-9 =0

x=-1 and x=9

the object will hit the ground at x=9
