Step-by-step explanation:
<u>Functions</u>
In a function, an independent variable, let's call it x is related to a dependent variable y and it can be expressed as:
y = f(x)
Let's consider the functions given in the question, where the equation that represents a company's yearly sales is:
And the equation that represents the same company's yearly expenses is:
The company's profit function P(x) can be found as the difference between S(x) and E(x), thus:
Operating:
Simplifying, the profit function for this company is:
The measure of AEC is 115°.
AED and AEC are supplementary, meaning AED + AEC = 180°
AED + 65° = 180
AED = 115°
14720 is answer. or product
Answer: Choice C
==========================================
Reason:
The portion on the left represents 
because of the open circle at -2 and shading pointing to the left. This represents all numbers smaller than -2.
The portion on the right represents all values that are 4 or larger; hence 
. Note the use of a closed circle at 4 to include this value.
We connect those two inequalities with the keyword "or" because x can only pick one of those options, but not both at the same time.
