A circle of radius 2 has its centre at (2, 0) and another circle of radius 1 has its centre at (5, 0). A line is tangent to the two circles at point in the first quadrant. The y-intercept of the tangent line is

A circle with centre at (15,-3) is tangent to y=(x^(2))/(3) at a point in the first quadrant.The radius of the circle is equal to

One circle has a radius of 5 and its centre at (0,5). A second circle has a radius of 12 and its centre at (12,0). What is the length of a radius of a third circle which passes through the centre of the second circle and both the points of intersection of the first two circles.

If the line x+3y=0 is tangent at (0,0) to the circle of radius 1, then the centre of one such circle is

If the line x+3y=0 is the tangent at (0,0) to the circle of radius 1, then the centre of one sum circle is

If the line x+3y=0 is tangent at (0,0) to the circle of radius 1, then the centre of one such circle is

A circle of radius 5 has its centre on the negative x-axis and passes through the point (2,3). The intercept made by the circle on the y -axis is
