If a line along a chord of the circle 4x2 + 4y2 - Sarthaks

WebIf a line along a chord of the circle $4 x^ {2}+4 y^ {2}+120 x+675=0$, passes through the point $ (-30,0)$ and is tangent to the parabola $y^ {2}=30 x$, then the length of this … WebStep 1: Determine the points of intersections. The equation of the circle: x 2 + y 2 = r 2 _ 1. The equation of the straight line: y - 2 x = 3. ⇒ y = 2 x + 3 _ 2. Put y = 2 x + 3 in equation … WebWe know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. So add 21 to both sides to get the constant term to the righthand side of the equation. x^2 + y^2 -4y = 21. Then complete the square for the y terms. x^2 + y^2 - 4y + 4 = 21 + 4. can\u0027t say for certain
