Question

Giancarlo is hitting a baseball for an experiment. He is using: h(t) =- 167 + 72t to model the height of the ball (in feet) as a function of time (in seconds). Evaluate and interpret h(2).

A. h(2) = -23 feet, the ball is 23 feet below the starting point.
B. h(2) = 5 feet, the ball is 5 feet above the starting point.
C. h(2) = 7 feet, the ball is 7 feet above the starting point.
D. h(2) = 239 feet, the ball is 239 feet above the starting point.

Answer 1

To evaluate and interpret h(2) for the given function h(t) = -167 + 72t, substitute t = 2 into the function to find that h(2) = -23 feet, indicating that the ball is 23 feet below the starting point.

Step-by-step explanation:

To evaluate and interpret h(2) for the given function h(t) = -167 + 72t, we substitute t = 2 into the function.

h(2) = -167 + 72(2)

h(2) = -167 + 144

h(2) = -23 feet

Therefore, the correct option is A. h(2) = -23 feet, indicating that the ball is 23 feet below the starting point.
