So the y axis is the vertical line and the x axis is the horizontal line. There are also four quadrants, the top right one is quadrant one, the top left one is quadrant two, the bottoms left one is quadrant three, and the bottom right one is quadrant four. Since all of your pairs are positive you will only use quadrant one to plot your points. X is the top line on that little table that shows all of the number pairs. So the first pair to plot on the graph is (2,1) you would count two points right on the x axis and the one up on the y axis. Do you understand that? Let me know it’s a little confusing, the x always go first and I just showed you how to do one of those. Can you mark brainliest by any chance?
Answer:
b)15
Step-by-step explanation:
13+2=15
Hope that helps
Step One
Develop a formula for the perimeter.
Argument
What you see is a semicircle going upwards and another one going downwards. Two semicircles =1 circle.
The "perimeter" [Circumfrence] of a whole circle = 2*pi*r
We are told that whatever you call this the perimeter is 8pi + 16
Step Two
Set up the equation
8pi + 16 = 2*pi*r + 4r Including the line connecting these two.
Step Three
Take out the common factors on the left and right.
8(pi + 2) = 2r(pi + 2) Divide both sides by pi + 2
8 = 2r Divide by 2
4 = r
Sorry. I didn't know the meaning of perimeter. Mathmate is perfectly correct.
The answer would be c hope that helped
