The surface area of the entire cube is 40.5 square inches
Here, we want to get the surface area of a cube given the measure of the area of one of the faces
Looking at the net of a cube, we can identify six identical and equal-dimension faces

A relation is said to be a function when each input value is related to only one output.
It can also be said that a function is a relation that has only output for any unique input.
In a function, each x-value is related to only one output.
From the relation given here, we have a straight-line graph. Here, each x-value is related to only one y-value.
Since each x-value is related to only one y-value, this relation is a function.

Which statement is true if the quantity demanded of a good decreases by 10% while consumer incomes increase by 2 %? (5 points)
O The income elasticity of demand is -20, and the good is inferior.
The income elasticity of demand is -5, and the good is inferior.
The income elasticity of demand is 0.2, and the good is normal.
The income elasticity of demand is 5, and the good is inferior.
The income elasticity of demand is 20, and the good is normal.
Answers
Based on the decrease in the quantity demanded and the increase in income, the true statement is The income elasticity of demand is -5, and the good is inferior.
How to find the income elasticity?The income elasticity of a good can be found by the formula:
= Change in quantity demanded / Change in income
= -10% / 2%
= - 5
When the income elasticity of demand for a good is negative, it means that it is an inferior good. This is because people only buy them because its what they can afford but if income rises, people stop buying them.

Consider functions f and g.
Answers
The correct option regarding the multiplication of the functions f(x) and g(x) is given by:
C. [tex](f \times g)(x) = \frac{x^2 + 6x + 8}{x^2 + 2x - 15}, x \neq -5, x \neq 3[/tex]
Multiplication of functionsTo multiply two rational functions, we multiply the numerators of each function and the denominator of each function to generate the rational functions.
In the context of this problem, before multiplying the functions, we can simplify them.
Function f(x) is given by:
[tex]f(x) = \frac{x^2 - 16}{x^2 + 3x - 10}[/tex]
The numerator and the denominator can be simplified as follows:
Numerator: (x + 4)(x - 4): applying subtraction of perfect squares.Denominator: (x + 5)(x - 2): due to it's roots.Function g(x) is given by:
[tex]g(x) = \frac{x^2 - 4}{x^2 - 7x + 12}[/tex]
The numerator and the denominator can be simplified as follows:
Numerator: (x + 2)(x - 2): applying subtraction of perfect squares.Denominator: (x - 3)(x - 4): due to it's roots.Then the multiplication function is:
[tex](f \times g)(x) = \frac{(x + 4)(x - 4)}{(x + 5)(x - 2)} \times \frac{(x + 2)(x - 2)}{(x - 3)(x - 4)}[/tex]
The common terms (x - 4) and (x - 2) are simplified, hence the function is given by:
[tex](f \times g)(x) = \frac{x + 4}{x + 5} \times \frac{x + 2}{x - 3} = \frac{x^2 + 6x + 8}{x^2 + 2x - 15}[/tex]
Hence option C is correct, with x = -5 and x = 3 being removed from the function due to the fact that they are the zeros of the denominator.
