Question

NEED HELP WILL GIVE 30 POINTS The table shows how an elevator 500 feet above the ground is descending at a steady rate. Which equation represents the height, h(t), of the elevator in feet, as a function of t, the number of seconds during which it has been descending? A h(t) = 5t + 500 B h(t) = 5t – 500 C h(t) = –5t + 500 D h(t) = –5t – 500

Answer 1

The correct answer is: h(t) = -5t + 500; from the table it is visible that the time difference is 5 seconds; the sign before 500 must be be "+", for we're talking about 500 feet above the ground. 

Answer 2

The answer is h(t) = –5t + 500
