Algebra.Com's Answer #14102 by venugopalramana(3286)![]() ![]() You can put this solution on YOUR website! Find the equations of the circles that are tangent to the x axis and have a radius of length five units. In each case, the abscissa of the center is -3.(There is more than one circle that satisfies these conditions) \n" ); document.write( "WHEN THE CIRCLE IS TANGENT TO X AXIS ,IT MEANS ITS CENTRE IS AT A DISTANCE EQUAL TO RADIUS OF THE CIRCLE FROM THE X AXIS .THAT IS Y COORDINATE OF CENTRE OF CIRCLE = 5 OR -5 \n" ); document.write( "ABSCISSA OF CENTRE IS GIVEN AS -3. \n" ); document.write( "HENCE CENTRE IS EITHER (-3,5).....OR (-3,-5)..ITS RADIUS =5 \n" ); document.write( "HENCE EQN OF 2 POSSIBLE CIRCLES ARE \n" ); document.write( "(X+3)^2+(Y-5)^2 = 5^2=25...................I \n" ); document.write( "OR \n" ); document.write( "(X+3)^2+(Y+5)^2=25........................II \n" ); document.write( " |
