Answer:
No
Reasoning:
If something is a perfect cube, it is able to be put under a cube root (
) and will result in an integer (a non-decimal number > 0, basically). 
So let's calculate 
, and see if the result is an integer.
 = 3.634....... 
As you can see, the result is not an integer, therefore 48 is not a perfect cube.
 
        
             
        
        
        
Answer:
All of them. 
Step-by-step explanation:
For rational functions, the domain is all real numbers <em>except</em> for the zeros of the denominator. 
Therefore, to find the x-values that are not in the domain, we need to solve for the zeros of the denominator. Therefore, set the denominator to zero: 

Zero Product Property: 

Solve for the x in each of the three equations. The first one is already solved. Thus: 

Thus, the values that <em>cannot</em> be in the domain of the rational function is:

7 and 1/2 mile because 2,640=1.5 miles
4-1.5=2.5+5=7.5
