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 12 inches. • The period is the circumference of the tire (2pi r). Start the cycle when the spot is at the top of the tire. (answer choices in picture)​

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
