Its height (in meters), x seconds after the launch, is modeled by:
h(x)=-5x2verb +20x+60
What is the height of the object at the time of launch?

Answer :

Answer:

60 feet

Step-by-step explanation:

The height, h (in meters), of the object launched from a platform is represented by the equation

[tex]h=h(x)=-5x^2+20x+60[/tex]

where x is the time (in seconds) passed after the launch.

The time of launch is [tex]x=0[/tex] (0 seconds passed after the launch)

Substitute [tex]x=0[/tex] to find the height:

[tex]h=h(0)=-5\cdot 0^2+20\cdot 0+60=60\ feet[/tex]
