Question 1043132: Volume of a Trough Water is running into a trapezoidal
trough. The volume V, in cubic feet, of water in the trough
is given by V= 32d2+32d, where d is the depth, in feet, of
the water in the trough. Find the depth of the water when
the volume is 850 cubic feet. Round to the nearest tenth of
a foot

.

As I understand your post, you want to find the value of d from the quadratic equation

 = 850.

Write it in the standard form

 = .

Apply the quadratic formula.

If you don't know what is the quadratic formula, or if you are not sure, then consult the lessons
