Let `A (0,2),B` and C be points on parabola `y^(2)+x +4` such that `/_CBA (pi)/(2)`. Then the range of ordinate of C is

A(0,2),B and C are points on parabola y^(2)=x+4 such that /_CBA=(pi)/(2), then find the least positive value of ordinate of C.

Given A(0,2) and two points B and C on parabola y^(2)=x+4 ,such that AB prependicular BC ,then the range of y coordinate of point C is

Let A(4,-4) and B(9,6) be points on the parabola y^(2)=4x. Let C be chosen on the on the arc AOB of the parabola where O is the origin such that the area of DeltaACB is maximum. Then the area (in sq. units) of DeltaACB is :

Let p be a point on the parabola y^(2)=4ax then the abscissa of p ,the ordinates of p and the latus rectum are in

Let C be the locus of the mirror image of a point on the parabola y^(2)=4x with respect to the line y=x. Then the equation of tangent to C at P(2, 1) is :

Let A(3, 2) and B(6, 5) be two points and a point C (x,y) is chosen on the line y=x such that AC+BC is minimum, then the co-ordinates of C are:

If three distinct normals can be drawn to the parabola y^(2)-2y=4x-9 from the point (2a, 0) then range of values of a is
