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
The equation of the tangents drawn from (3,2) to the parabola x2 = 4y are
The line y =2x + k is a normal to the parabola y2= 4x,then=
The locus of the point of intersection of perpendicular tangents to the parabola y2=4ax is
If a circle cuts the parabola y2 = 4ax in four points, then the algebraic sum of oridinates of the four points is
The equation of the tangent to the parabola y2 = 8x and which is parallel to the line x – y + 3 = 0
AB is a chord of the parabola y2 = 4ax with vertex at A. BC is drawn perpendicular to AB meeting the axis at C.The projection of BC on the axis of the parabola is
If the vertex of the parabola y = x2 – 8x + c lies on x – axis, then the value of c is
