The reason for this has to do with finding the area of a square. When you are looking for the area of a square, you use the rectangle formula (since a square is also a rectangle).
The formula is Area = Length * Width
However, since in a square, the length and width are the same, both get changed to the word "Side". As a result, we get the following formula.
Area = Side * Side
This can be simplified to:
Area = Side^2.
Since each number to the second power also shows the area of a square with that given length sides, it can also be called "squared".
Answer:
$532.50 / (number of members)
Step-by-step explanation:
Let m represent the number of members.
The net income (after subtracting the cost of the popcorn) was $532.50.
Thus, the amount of $ raised per member of the club was $532.50/m
I think the answer would be B

.
Step-by-step explanation:
According to the given information, vector stands in the 4th Quadrant (
, 
) and direction of the vector (
) in sexagesimal degrees, is determined by following definition:
,
Please notice that angle represents a function with a periodicity of 360°.
If we know that 
and 
, then the direction of the vector is:
The family of directions of the given vector is represented by , .
