Question 1149613: The path of the longest shot put by the women's track team at Sun Devil U is modeled by h(x)=-0.017x^2+1.09x+6.1, where x represents the horizontal distance from the start and h(x) is the height of the shot put above ground. (Both x and h(x) are measured in feet)
a. Determine h(40). Round your answer to 2 decimal places. Then explain what your answer means in the context of the problem.
b. Determine the numerical value of the vertical intercept and explain what this means in the context of the problem.
c. Determine the numerical values of the vertex intercept and explain what they mean in the context of the problem.
d. How far from the start did the shot put strike the ground? Round your answer to 2 decimal places.
