To find: The maximum height of the water.
Answer to Problem 67E
Explanation of Solution
Given: The height h (in feet) of the water above the main nozzle t seconds after water left the nozzle modeled by the function,
The model of height of water of nozzle,
First method: Using vertex form
The maximum height at vertex,
Second method: Using intercept
Find x -intercept and maximum at mid value of x -intercept.
Mid value of intercept,
Third method: Derivative method
Above three method, vertex form is best method to find maximum.
The maximum height of water of nozzle is 125.44 feet.
