12 POINTS!! PLEASE HELP! You ride through some wet paint on your bike, creating a red
spot on the tire. Write a cosine equation to model the height
of the red spot over the distance you ride.

• Your bike tire has a radius (r) of 13 inches

• The period is the circumference of the tire (2 πr)

• Start the cycle when the spot is at the top of the tire

Harold wrote this equation to model the level of water in a pool over time. the variable x represents time in hours. f(x) = 3,500 - 225x which statements about the situation are true? check all that apply. the water level is rising. the water level is falling. the initial level of water in the pool was 3,500 units. the initial level of water in the pool was 225 units. the pool was empty after 14 hours. the water was 2,600 units high after 4 hours.
