15. The height above the ground of a Ferris wheel car is modelled with the equation h(t) = -15 cos + 17, whereh is the height (in metres) and t is the time (in seconds). %3D a) What are the maximum and minimum heights of the ride? b) How long does it take for the Ferris wheel to go around once? c) Use the secant method to find the approximate instantaneous rate of change of height at 20 seconds.
