Two identical food packets were dropped from a helicopter. The first food packet was dropped from a height of 1,681 feet and the second food packet was dropped

Question

A. h1(t) = −4t2 + 41 is a vertical translation of h2(t) = −4t2 + 31.
The y-intercept of h2 is 10 ft greater than that of h1.

B. h1(t) = −16t2 + 1681 is a vertical translation of h2(t) = −16t2 + 961.
The y-intercept of h2 is 720 ft greater than that of h1.

C. h1(t) = −4t2 + 41 is a vertical translation of h2(t) = −16t2 + 31.
The y-intercept of h2 is 10 ft less than that of h1.

D. h1(t) = −16t2 + 1681 is a vertical translation of h2(t) = −16t2 + 961.
The y-intercept of h2 is 720 ft less than that of h1.

Answer 1

D is the best answer, even given the missing number for h2 when it was dropped.

-16t^2 is needed as the effect of gravity, so only B or D could be correct

h1 has a larger y intercept, so D is correct or the "best answer" given what was given.
