Answer
a. -3/5
b. (0,2)
c. The line is decreasing.
Explanation
In this form, the number that accompanies the x correspond to the slope and the value of the independent number to the y-intercept.
The line is decreasing because the slope is negative.
To determine the time it takes for the maximum height to be achieved, derive the equation and equate to zero.
h = -16t² + 112t + 30
dh / dt = 0 = 2(-16)t + 112
The value of t is 3.5 s. Substitute this value of time to the equation for h,
h = -16 x (3.5 s)² + 112 x 3.5 s + 30 = 226 ft
Thus, the answer is letter D.
