As you ride a Ferris wheel, the height that you are above ground varies periodically. Consider the point at the center of the wheel to be the equilibrium point. Suppose the diameter of the Ferris wheel is 32 feet and travels at a rate of 3 revolutions per minute. At the highest point, a seat on the Ferris wheel is 39 feet above the ground.

Eric has challenged himself to walk 24,000 steps in 4 days. if eric walks the same number of steps each day, which function represents the number of steps eric still needs to walk to reach his goal with respect to the number of days since he started his challenge? a. y = 8,000x − 24,000 b. y = -8,000x + 24,000 c. y = 6,000x − 24,000 d. y = -6,000x + 24,000
