Answer 2

Explanation:

Given the height of the object covered by the ball modeled by the function;

h(x) = -16x^2 + 48x + 64

To determine the height covered by the ball after 1.2 secs, we will simply substitute x = 1.2s into the formula and find h(x) as shown;

h(1.2) = -16(1.2)^2 + 48(1.2) + 64

h(1.2) = -16(1.44) + 48(1.2) + 64

h(1.2) = -23.04 + 57.6 + 64

h(1.2) = 98.56m

This means that the ball have covered 98.56m in 1.2sseconds
