8. What transformation do you need to apply to change a sin function to a cos function? 9. The movement of a chair on a Ferris Wheel can be modeled using the equation y = -'lO cos (3x) + 10.5 (where x is in seconds and y is in metres). Describe how how the equation relates to the Ferris Wheel in terms of the following: A. how long it takes for one rotation B. the size of the Ferris Wheel C. the location of the axle of the Ferris Wheel D. the height of a rider after 45 seconds 10. A model of a Ferris Wheel is 30 cm in diameter with an axle that is 18 cm off the oor. It rotates completely every 30 seconds. Using the base equation for a sinusoidal function y : asin(k(a: 7 0)) + d or y : acos(k(m * 0)) + d
