The parametric equations of the circle x^2+y^2+2 x-4 y-4=0 are

Options

  1. Ax=-1+3 , y=2+3
  2. Bx=1+3 , y=-2+3
  3. Cx=-1+3 , y=-2+3
  4. Dx=1+3 , y=-2+3

Correct answer

A. x=-1+3 , y=2+3

Step-by-step solution

Given equation of circle is aligned & x^2+y^2+2 x-4 y-4=0 & (x^2+2 x+1 )+ (y^2-4 y+4 )-4-5=0 & (x+1)^2+(y-2)^2=3^2 aligned Parametric equation of circle is x=-1+3 , y=2+3

A circle touches both the coordinate axes and the straight line L 4 x +3 y -6=0 in the first quadrant. If this circle lies below the line L =0 , then the equation of that circle is 2025If the smallest circle through the points of intersection of x^2+y^2=a^2 and x +y =p, 0 < p < a is x^2+y^2-a^2+ (x +y -p)=0 then = 2025If the lines 3 x-4 y+4=0 and 6 x-8 y-7=0 are the tangents to the same circle, then the area of that circle (in sq.units) is 2025Circles are drawn through the point (2,0) to cut intercepts of length 5 units on the X -axis.
