The height of a rider on a Ferris wheel, in metres, can be modelled using the function , where is the angle of rotation. (in calculator use x instead of ) Use a graphing calculator to graph the function.
What is the radius of the Ferris Wheel?
At what height was the rider when the ride began?
How would the function and the graph change if the Ferris wheel turned in the opposite direction?

Solve the system by the elimination method. x + y - 6 = 0 x - y - 8 = 0 when you eliminate y , what is the resulting equation? 2x = -14 2x = 14 -2x = 14
