Answer:

8.86

Step-by-step explanation:

Im guessing you want the rectangles area

Finding circle area do radius times radius times 3.14 so 1 x 1 = 1 x 3.14 = 3.14

Rectangle area is length times width so 3 x 4 = 12 - 3.14 = 8.86

Answer:

The functions have the same y-intercept.

OPTION C is correct.

Step-by-step explanation:

<u>DEFINITIONS AND FORMULAS</u>

The equation of a linear graph is given to be:

y=mx+b

Where m is the slope of the graph and b is the y-intercept.

To calculate the slope given a table, we can use the formula:

m=\frac{y^{2}-y^{1}  }{{}x^2 -x^1}

<u>SOLUTION</u>

<u>Function 1:</u> The equation of the graph is given to be

p=-\frac{3}{2}r-5

Therefore, the y-intercept of the graph is given to be:

b=-5

<u>Function 2: Recall that the y-intercept of a graph is the y-value when x = 0.</u>

On checking the graph, we can see that when r = 0, p = -5.

Therefore, the y-intercept is:

b=-5

ANSWER

The functions have the same y-intercept.

OPTION C is correct.
