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?

h (t) = 5t + 500

h (t) = 5t - 500

h (t) = - 5t + 500

h (t) = - 5t - 500

''We are given that the elevator is descending, so the coefficient of t must be negative. The elevator's initial position is 500 feet above the ground, so this is a positive value of + 500. Therefore the only choice that fits is h (t) = - 5t + 500.'' - Blitztiger
