Water flows at a rate of 9000 cubic inches per minute into a cylindrical tank. the tank has a diameter of 144 inches and a height of 72 inches. what is the height, in inches, of the water in the tank after 10 minutes? round your answer to the nearest tenth.

5.5 inches

Step-by-step explanation:

Water flows at a rate of  9000 cubic inches per minute into a cylindrical tank.

In 1 minute = 9000 cubic inches

in 10 minute = 9000 × 10 = 90000 cubic inches

Diameter = 144 inches

Radius = 144/2 = 72 inches

Now the volume of the water filled in the cylindrical tank in 10 minutes = πr²h = 90000 cubic inches.

h = 90000/(πr²)

Therefore the height of the water filled in tank after 10 minutes will be 5.5 inches.

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
