Find the value of p for which curves `x^2=9p(9-y)` and `x^2=p(y+1)` cut each other at right angles.

Find the value of p for which the curves x^(2) = 9 p(9 - y) and x^(2) = p(y + 1) cuts each other at right angles.

If the curves y^2=6x,9x^2+by^2=16 , cut each other at right angles then the value of b is

If the two curves x=y^2 and xy=k cut each other at right angles than a possible value of "K" is

Find the value of p if lines 3y - 2x = 4 and 4y - px = 2 are perpendicular to each other .

If the curves y^(2) = 16x and 9x^(2)+by^(2) =16 cut each other at right angles, then the value of b is

Show that the curves x=y^2 and x y=k cut at right angles, if 8k^2=1 .
