Question #9b22f

Answer 1

C

Explanation:

The standard form of the `color(blue)"equation of a circle"` is.

`color(red)(bar(ul(|color(white)(2/2)color(black)((x-a)^2+(y-b)^2=r^2)color(white)(2/2)|)))`
where (a ,b) are the coordinates of the centre and r, the radius.

`"the centre "=(2,-5)" and radius "=12`

`rArra=2,b=-5" and "r=12`

substituting into the equation gives.

`(x-2)^2+(y-(-5))^2=12^2`

`rArr(x-2)^2+(y+5)^2=144toC`
