Answer to Problem 14CT
The required distance is 35.615 feet.
Explanation of Solution
Given information:
The model of the tosses:
Calculation:
The given model of tosses is
Rewrite the above equation as:
Simplify the expression
The above equation is vertex form.
So, the distance to the vertex is 15 and the maximum height is 4.25.
To find the maximum distance, solve the expression
Use the quadratic formula
Substitute 1 for a , −30 for b and −200 for c in the above formula and simplify for x .
Solve the above expression for x .
And,
The distance cannot be negative.
Hence, the required distance is 35.615 feet.
