Mr. V had a nail in his truck tire. The tire wasn't flat, but he had to go get it fixed. He drove at a constant speed to the shop, and the diameter (width) of the tire was 4 feet. Which rule could model the height of the nail from the ground? (HINT: The diameter is the entire way across the tire, which is double the amplitude.)
The appropriate rule to model the height of the nail from the ground is a sine or cosine function. These functions have an amplitude equal to half the range, which in this case would be half the diameter of the tire. Since the diameter of the tire is 4 feet, the amplitude would be 2 feet.
