Write an equation in standard form for the circle that statisfies these conditions
\n" ); document.write( "center(0,7) tangent to x-axis
\n" ); document.write( "**
\n" ); document.write( "If you make a rough sketch of given points, you will see that the radius=7
\n" ); document.write( "Standard form of equation for a circle: (x-h)^2+(y-k)^2=r^2, (h,k)=(x,y) coordinates of center, r=radius.
\n" ); document.write( "Equation of given circle
\n" ); document.write( "x^2+(y-7)^2=7^2
\n" ); document.write( "x^2+(y-7)^2=49
\n" ); document.write( "
\n" );
