Answer:
Step-by-step explanation:
(x + 2)^2 + (y -1 )^2 = 3^2
(x + 2)^2 + (y -1)^2 = 9
I have used Desmos to draw this for you. Notice that the center is not (2, -1) but is at -2,1 just as the question requested. The signs are always reversed when the center of a circle must be obtained by squaring the numbers in parenthesis.
Further two points are shown. The one you should pay attention to is (-2,4) which is 3 units away from the center. The other point is also 3 units away, but you have to use the distance formula which you may not be familiar with. If you measure it with a ruler, you will find it is the same distance away from the center as (-2,4) is Since they are equal, they both must represent the length of the radius.
Answer:
width = area/Length
= 26mn^3p^4p^8 / 13mn^3p^6
Use long division to divide 13/15.
This will give you 0.8666... (repeating)
Multiply by 100 to get your percent.
The answer should be c- 52
The answer is eight and one.
Sum: 8 + 1=9
Product:8*1=8
