Answer to Problem 47E
14 feet
Explanation of Solution
Given information:
The path of the T-shirt launched by air cannon is given by the function:
The height of the bleachers is given by the function:
Here y represents the vertical height (in feet) and x represents the horizontal distance (in feet).
Calculation:
Consider, the equation (2),
The height at which the T-shirt land in the bleachers is given by the point of intersection of the equations (1) and (3), so substituting equation (3) in equation (1),
By the zero product property,
Or
But x represents distance so, it can’t be negative. So, solution is
Substitute
