Question

Select interior, exterior, or on the circle (x - 5) 2 + (y + 3) 2 = 25 for the following point.

(2, 3)

Answer 1

HI!

Answer 2

do you know the center and radius of this circle (hint, it is in the right form for you to eyeball it )

Answer 3

is it 25?

Answer 4

is what 25?

Answer 5

the radius.. i dont know im not so good with geometry :/

Answer 6

general form of a circle with center \((h,k)\) and radius \(r\) is
\[(x-h)^2+(y-k)^2=r^2\]

Answer 7

you have
\[(x-5)^2+(y+3)^2=25\] so you can read off the center and radius from the equation

Answer 8

so is it interior?

Answer 9

Or exterior?
