As you ride a Ferris Wheel, your distance from the ground varies sinusoidally with time. Suppose you start at the top of the Ferris Wheel, whicih is 80 feet above ground when the Ferris Wheel is filled and starts. The diameter of the wheel is 70 feet, and the wheel makes one revolution every 10 seconds. The equation modeling this event is y = A cos or sin (Bx) + D. Fill in the blanks. A = Fill in cos or sin Round to 4 decimal places. B = D =
