Question 1143817
The equation y = -x^2 + 10 models the flight of a projectile where y is the height of the projectile in meters x seconds after launch. Determine the height after:

A) 1 second
x = 1
h = -1 + 10 = 9 meters
--------------------
B) 3 seconds
x = 3
h = -9 + 10 = 1 meter
---------------------
C) 10 seconds
---> -90 meters.  The projectile impacts before 10 seconds.
====================
y = -x^2 + 10 is not the usual equation for projectiles, tho it could be valid on some planet or asteroid.
