z is greater than or equal to negative three halves

Step-by-step explanation:

subtract 3/4 from each side then simplify.

Step-by-step explanation:

The height is given by

We need to find when it strikes the water surface,

At water surface h = 0 feet

Substituting

Solving this quadratic equation to get x.

                 -32x² + 2500x + 500000 = 0

                  32x² - 2500x - 500000 = 0

                  x = 170 .02 feet  or  x = -91.90 feet

Negative x is not possible

Horizontal distance when projectile strikes water surface = 170 .02 feet
