Gus has a fish tank that holds 4710 inches cubed of water. he is using a cylinder shaped bucket with a radius of 5 inches and a height of 20 inches to fill the tank. how many times will gus need to fill the bucket to completely fill the fish tank if he doesn't spill a drop

Hence, the number of times will Gus need to fill the bucket to completely fill the fish tank if he doesn't spill a drop is:

                        3 times

The amount of water that a tank can hold is: 4710 inches cube.

This means that the volume of tank is: 4710 cubic inches.

Also, the bucket is in the shape of a cylinder with radius 5 inches and height 20 inches.

This means that the Volume of bucket is given by:

where r denotes radius and h denotes height.

Hence, Volume of bucket is:

Let n be the number of times Gus need to fill the bucket to completely fill the fish tank

Hence, we have:

 Volume of fish tank= n × Volume of Bucket

i.e.  

               Hence, the answer is:

                          3

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
