The average seated gorilla breathes in and out every 4 seconds. The average minimum amount of air in the lungs is 0.08 liter, and the average maximum amount of air in the lungs is 0.82 liter. Suppose the lungs have a minimum amount of air at t = 0, where t is the time in seconds. Make a function that models the amount of air in the lungs.

A. y = -0.37 cos /2 t + 0.45

B. y = 0.82 cos /2 t + 0.45

C. y = -0.37 cos /2 t + 0.82

D. y = 0.82 cos /2 t + 0.08
