**intermediate algebra**

A projectile is launched directly upward from the top of a 112 - foot building with an initial velocity (speed) of 96 feet per second. This translates to the h(t) = -16t^2 + 96t + 112 where h(t) is the height of the projectile in feet and t is the time in seconds after it is ...

**Intermediate Algebra**

If a projectile is fired straight upward from the ground with an inital speed of 96 feet per second, then its height (h) in feet after t seconds is given by the equation h(t)=-16t^2+96t Find the maximum height of the projectile.
