a. The height over time of a person riding a Ferris wheel can be modeled using a sinusoidal function. Sketch a height versus time graph for a person riding a Ferris wheel with the following characteristics: The person reaches a maximum of 15 m. The person reaches a minimum of 1 m. It takes 70 s for the Ferris wheel to tum once. At time 0, the person is at height 1 m. Describe how you graphed the function and use appropriate domain and range values. b. 5 marks Determine an equation for the following sinusoidal function. Show and explain your work
