Answer:
y = (x +2)/(x -3)
Step-by-step explanation:
A rational function is a function (y = ...) that has a definition that is the ratio of two polynomials.
Of the choices listed, the one attached is the rational function.
Given that grain is falling from a chute onto the ground, forming a conical pile whose diameter is always three times its height.
So if D is the diameter and h is the height of the conical pile then we can write:
D=3h
We know that diameter = 2r, where r is the radius
2r=3h
Volume of conical pile is given by formula
Given that volume is 1110 cubic feet.
Now plug the values of Volume and r into equation of volume
take cube root of both sides
7.78103342467=h
Hence height is approx 7.78 feet.
