A variable circle is drawn to touch the line `3x – 4y = 10` and also the circle `x^2 + y^2 = 1` externally then the locus of its centre is -

A variable circle is drawn to touch the line 3x4y=10 and also the circle x^(2)+y^(2)=1 externally then the locus of its centre is -

If a variable circle 'C' touches the x-axis and touches the circle x^2+(y-1)^2=1 externally, then the locus of centre of 'C' can be:

If a circle br drawn so as always to touch a given straight line and also a given circle externally then prove that the locus of its centre is a parabola.

apie circles are drawn touching the line x+5=0 and the circle x^(2)+y^(2)=4 externally.Show that locus of centre of this circle is a partrix and the focus,axis, vertex,directrix and extremities of latus rectum of this parabola.

A circle C touches the x-axis and the circle x ^(2) + (y-1) ^(2) =1 externally, then locus of the centre of the circle C is given by

A circle is given by x^2 + (y-1)^2 = 1 , another circle C touches it externally and also the x-axis, then the locus of its centre is :

Centre of a variable circle lies in first or fourth quadrant.This circle touches y-axis and also the circle x^(2)+y^(2)-4x=0 externally.Show that locus of centre of this variably.Show parabola.Find the direcrix and focus of this parabola.

Equation of the circle centred at (4, 3), touching the circle x^2 + y^2 = 1 externally is:

A circle is given by x^2 + (y-1) ^2 = 1 , another circle C touches it externally and also the x-axis, then the locus of center is:

A circle is given by x^2 + (y-1) ^2 = 1 , another circle C touches it externally and also the x-axis, then the locus of center is:
