If `x+y = 2` does not intersect any member offamily ofcircles `x^2 +y^2-ax=0` at two distinct points(a is a parameter). Then maximum value of `|a+4|` is

If the line y=x+2 does not intersect any member of the family of parabola y^(2)=ax,(a in R^(+)) at two distinct point,then maximum value of latus rectum of parabola is:

The two circles x^2+ y^2=r^2 and x^2+y^2-10x +16=0 intersect at two distinct points. Then

The two circles x^2+ y^2=r^2 and x^2+y^2-10x +16=0 intersect at two distinct points. Then

If x^2-4x+log_(1/2)a=0 does not have two distinct real roots, then maximum value of a is

The line y=mx+c intersects the circle x^(2)+y^(2)=r^(2) in two distinct points if

The line y=mx+c intersects the circle x^(2)+y^(2)=r^(2) in two distinct points if

If x^(2)-4x+log_((1)/(2))a=0 does not have two distinct real roots,then maximum value of a is

The line x+2y+a=0 intersects the circle x^2+y^2-4=0 at two distinct points A and B. Another line 12x-6y-41=0 intersects the circle x^2+y^2-4x-2y+1=0 at two distincts points C and D. The value of 'a' so that the line x+2y+a=0 intersects the circle x^2+y^2-4=0 at two distinct points A and B is

If the circle x^2+y^2-4x-8y-5=0 intersects the line 3x-4y=m at two distinct points, then find the values of m .
