The rectangle is 7 x 4 so the area is 28 sq cm
The triangle has a base of 4 and a height of 3.
The formula is A = 1/2 * b*h
You have 2 triangles so:
2(1/2)*4*3= 12 sq cm
Add together:
28 + 12= 40 sq cm
Using variable concepts, of dependent and independent variables, it is found that the dependent variable is the amount of sales dollars earned.
<h3>What is the relation between a function and the dependent and independent variables?</h3>
- A function has the following format: y = f(x).
- In which each value of y is a function of one value of x, and thus, <u>x is the independent variable and y is the dependent variable</u>.
- That is, the input of the function is the independent variable and the output is the dependent variable.
In this problem, the manager believes that the amount of sales dollars earned is a function of the number of contacts that the salesperson makes, hence:
- The number of contacts is the independent variable.
- The amount of sales dollars earned is the dependent variable.
