Answer:

Step-by-step explanation:
- A circle's equation consist on the following expression:
, where r is the magnitude of the radio, and (a,b) are the coordenates of the center of the circle. - In this case, a=2 and b= - 3, because the circle is centered in (x,y)=(2, - 3).
- The radio, which is the distance between the center of the radio to any point in its border, equals r=2 (because of the scale of the graphic, in this case two squares of the grid equal 2 units, then r=2).
- Finally, using the previous information to replace in the equation
, where the fact that r=2 and
was used.
Answer:
the first thing you learned is the base. then you can build off of it. just like math. you learn simple adding then you go onto multiplication and division.

Answer:
5
Step-by-step explanation:
18 = (240/100) x what;
what = 18 x (100/240);
what = 1800/240;
what = 7.5;
