5. Mrs. Mullen does competitive skydiving on the weekends. She jumps out of a plane and free-falls for almost 50 seconds, reaching terminal velocity. Then she opens her parachute and slows down until she finally reaches the ground where she lands running until she comes to a stop. The graph of her velocity V(t), over the time, t, of her dive is sketched. Which of the following statements are correct? Select all that apply.

A. The y-intercept represents her velocity when she jumped out of the plane. B. The y-intercept represents the initial height off the ground.

C. The function is decreasing over the interval 0 < t < 45 D. The function is decreasing over the interval 50 < t < 75

E. The x-intercept represents the time she opened her parachute.
