4. The largest Ferris Wheel in the world is the London Eye in England. The height (in metres) of a rider on the London Eye after t minutes can be described by the function h(t) = 67 sin[0.2094(t-30)] + 70.

a) At what time(s) will the rider be at the bottom of the Ferris wheel?
b) How long does it take for the Ferris wheel to go through one rotation?
c) What is the minimum value of this function? Explain the significance of this value.

Try graphing the equation out. The rider will be at the bottom of the Ferris wheel when the graph is at its lowest points. You should also be able to tell when the Ferris wheel goes through one rotation by the graph. The minimum value of the function...think about what the range of values of sin could be...that should give you a hint about what to do for the minimum value.
