1.A circus is testing two cannons that will shoot a clown through the air. The plan is to have the clowns shot out of the cannons at the same time, but different angles. They want them to be at the same height at some point so they can "high five" each other. The height, h, in feet, of the clowns at t seconds after being fired out of the cannons is given by the following equations:

Clown #1: h = - 0.05t² + 0.8t

Clown #2: h = - 0.06t^t + 0.9t

a)At what time after being fired from the cannons are the clowns at the same height?

b) What is the height when they "high five"?

2.The revenue for the school play is given by: R = -40t² + 250t, where "t" is the ticket price in dollars. The cost to produce the play is given by : C = 450 - 40t.

a). Sketch the graphs of both equations as seen on your calculator (indicate the window you used in the space provided).
