An object is launched from a platform.
its height (in meters), x seconds after the launch, is modeled by
h(x)=-5(x+1)(x-9)
what is the height of the object at the time of launch?
meters
answer as soon as possible !

45 meters

Step-by-step explanation:

If x represents the seconds after the launch, then the time of launch is when x=0 so you just need to solve for h(0)

h(0) = -5(1)(-9)

h(0) = 45

45 m

Step-by-step explanation:

At the time of launch, the time x = 0

Substitute x = 0 into h(x)

h(0) = - 5 (0 + 1)(0 - 9) = - 5(1)(- 9) = - 5 × - 9 = 45
