The lowest point y = a cos (b (x - c)) + d 3 of the wheel is 5 ft above the ground. Timmy -2 gets on the Ferris wheel at the bottom of the wheel when x = 0 seconds. -3 What is a? type your answer. 4 Write a negative cosine equation representing -4 Timmy's height, y, above the ground if x is in 5 -5 seconds. Next E y = -3 sin (2 (x - I)) + 1 6 O y= -3 cos (2 (x + 1)) + 1 y = -3 sin (2x - 1) + 1 7 y = 3 cos (2x) + 1 8 y = -3 cos (2x + 7) + 1 O y = 3 sin (2 (x + 3)) +1 9
