The number of common tangents to y^(2)=2012x and xy=(2013)^(2) is

The common tangent of x^(2)+y^(2)=4 and 2x^(2)+y^(2)=2 is

A common tangent to the circles x^(2)+y^(2)=4 and (x-3)^(2)+y^(2)=1 , is

A common tangent to x^(2)-2y^(2)=18 and x^(2)+y^(2)=9 is

A common tangent to x^(2) - 2y^(2) =18 and x^(2) + y^(2) = 9 is

The number of common tangents to the circles x^(2)+y^(2)-y=0and x^(2)+y^(2)+y=0 is

The number of common tangents of the circles x^(2) +y^(2) =16 and x^(2) +y^(2) -2y = 0 is :

Statement 1 : The number of common tangents to the circles x^(2) + y^(2) =4 and x^(2) + y^(2) -6x - 6y = 24 is 3. Statement 2 : If two circles touch each other externally thenit has two direct common tangents and one indirect common tangent.
