Cube A has a volume of 9 in3. Cube B has a volume of 5 in3. Which of the following expresses the ratio of the side length of Cube A to the side length of Cube B?
(A) 3 : 5 ^1/3
(B) 5^1/3 : 3^1/3
(C) 3^1/3 : 5^2/3
(D) 3^1/3 : 5^1/3
(E) 3^2/3 : 5^1/3
Using the formula for the volume of a cube, it is found that the expression which gives the ratio of the side length of Cube A to the side length of Cube B is:
[tex]r = \frac{3^{\frac{2}{3}}}{5^{\frac{1}{3}}}[/tex]
Which means that option E is correct.
The volume of a cube of side length l is given by:
[tex]V = l^3[/tex]
For Cube A, the volume is of 9 cubic inches, hence:
[tex]l_a^3 = 9[/tex]
[tex]l_a = \sqrt[3]{9}[/tex]
[tex]l_a = 9^{\frac{1}{3}}[/tex]
[tex]l_a = 3^{\frac{2}{3}}[/tex]
For Cube B, the volume is of 5 cubic inches, hence:
[tex]l_b^3 = 5[/tex]
[tex]l_b = \sqrt[3]{5}[/tex]
[tex]l_b = 5^{\frac{1}{3}}[/tex]
Then, the ratio is:
[tex]r = \frac{l_a}{l_b} = \frac{3^{\frac{2}{3}}}{5^{\frac{1}{3}}}[/tex]

The given relation is not a function.
What is Function?A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.
Given a table of x and y values.
We have to determine the relation is a function or not.
By the definition of functions, a relation is a function if an input value does not map to two output values.
That is, an x value will not map to two y values.
From the table,
x = 1 maps to two y values -2 and -3.
This is not possible for functions.
So this is not a function.
Hence the relation is not a function.

The hint is in the slopes which is the number in front of x. Both equations have a slope of 1/2
The y intercepts are different (4 for the top one 2 for the bottom one). That tells you that you have two lines and not one of top of the other. These two lines never meet, because the slopes are the same. Therefore there are no values that both lines have in common.
That makes the answer none.
