Question 201100
The time t (in seconds) that it takes for a cliff diver to reach the water is a function of the
height h (in feet) from which he dives:
t = sqrt h /16
Find the exact time that it takes for a diver to hit the water when diving from 25 feet.
t = sqrt h/16 = sqrt 25/16
t = 5/4 seconds = 1.25 seconds

Solve by factoring.
z^2 - 3z - 18 = 0
-6 * 3 = -18
-6 + 3 = -3
(z-6)*(x+3) = 0
z = 6
z = -3

Simplify the following radical:
3 − 64c^15/3 sqrt x^15
{{{(3-64c^15)/(3*sqrt(x^15))}}}
= {{{(3-64c^15)*sqrt(x)/(3*sqrt(x^16))}}}
= {{{(3-64c^15)*sqrt(x)/(3*x^8)}}}
