The equation obtained by transforming x^2+y^2-6 x+10 y-2=0 to the parallel axis through (3,-5) is
Options
- Ax^2+y^2=16
- Bx^2+y^2=9
- Cx^2+y^2=25
- Dx^2+y^2=36
Correct answer
D. x^2+y^2=36
Step-by-step solution
Given equation is aligned x^2+y^2-6 x+10 y-2 & =0 (x-3)^2+(y+5)^2 & =36 aligned The equation obtained by transforming (x-3)^2+(y+5)^2=36 to parallel axis through (3,-5) is Put x-3=h and y+5=k h^2+k^2=36 i.e. x^2+y^2=36
