a tennis ball is dropped from the top of a tall building. the ball's height, in meters, t seconds after it is released is h(t)=-5t+175

Question

Find h(4) and give a real-world meaning for this value

Answer 1

h(t) = -5 * t + 175

To find h(4), we replace every t in that formula with 4:

h(4) = -5 * 4 + 175 = 155

So the answer is 155. According to this formula, that means that the ball's height is 155 meters, 4 seconds after dropping it from the top of the building.

Hope that helps!
