Answer:
750 ft^3
Step-by-step explanation:
Given that the cones are similar, the first step would be to determine their linear scale factor; That is the ratio of their radii;
The next step is to determine the volume scale factors. Since the linear scale factor is 2.5, the volume scale factor would be;
volume scale factor = (linear scale factor)^3
= 2.5^3 = 125/8
The volume of Cone B will thus be;
volume of Cone A * volume scale factor = 48 * 125/8 = 750 ft^3
The easiest way to find the inverse of a function is to swap the x and y, meaning:
We have the function
. Let's call our outputs "y", so we have 
. To find the inverse, we're going to change the x and the y's position in the equation, so we have 
. Then all we need to do is solve for y:
We have the function
