Answer: Choice C) 40 </h3>
==========================================================
Work Shown:
Plug in x = 0
This indicates that (0,1) is on the curve. This is the y intercept.
Do the same for x = 2
So we know that (2,81) is another point on this curve.
We need to find the slope of the line through (0,1) and (2,81) to get the slope of the secant line we want.
The slope of the line through (0,1) and (2,81) is m = 40. This value of m is exactly the slope of the secant line your teacher is asking for. This is why the answer is choice C.
Answer:
C is dependent variable
S is independent variable
Step-by-step explanation:
Here, give the equation, we are told to identify the independent and the dependent variable
When we talk of the independent variable, it is that variable which values does not depend on whatever values the second variable in the equation has. It is that variable that is used to find the other variable in the equation
While the dependent variable depends on the values we input in the equation. It is the variable that we arrive at after plugging different values for the independent variable
now looking at the question, the equation we have is as follows;
c = 0.09s
To get the value of c which is the cost , we have to input different values of a. As is the amount in sales that we have that will yield the value of the commission to be received
Thus, we can categorically say that the values of the commission are dependent on the values we get from the sales
Hence, while commission represents the dependent variable, the values of the sales are the independent variables
