The length of the chord intercepted bt the parabola y = x2 + 3x on the line x + y = 5 is
The equation of the axis of the parabola (y + 3)2 = 4(x – 2) is
Two straight lines are perpendicular to each other. One of them touches the parabola y2 = 4a (x + a) and the other touches y2 = 4b (x + b). the locus of the point of intersectionof the two lines is
The locus of the point of intersection of two tangents to the parabola y2 = 4ax which make the angle θ1 and θ2 with the axis so that cot θ1 + cos θ2 = k is
The equation of the tangent to the parabola y2 = 12x at (3, -6) is
The straight line x + y = k touches the parabola y = x-x2, if k =
The locus of the midpoint of chords of the parabola y2 = 4ax parallel to the line y = mx + c is
A straight line which makes equal intercepts on positive X and Y axes and which is at a distance 1 unit from the origin intersects the straight line y =2x+3+√2 at (x0, y0). Then 2x0+y0=
If the normals from any point to the parabola x2 = 4y cuts the line y = 2 in points whose abscissa are in A.P, then the slopes of the tangents at the 3 conormal points are in
