4. The height of a rocket launched upward from a 85-foot cliff is modeled by the function h(t) = -16t2 + 35t + 85, where his height in feet and t is time in seconds.
a) What is the maximum height of the rocket?
b) How long does it take for the rocket to reach the maximum height?
c) How long does it take the rocket to reach the ground at the bottom of the cliff?
In the 7ern Product Property to solve each equation.

step-by-step explanation:

hjkj

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
