write the equation in standard form. name the center, the length of the minor and major axis, and direction.
\n" ); document.write( " 5x^2+9y^2=720
\n" ); document.write( " x^2+9y^2-4x+54y+49=0\r
\n" ); document.write( "\n" ); document.write( "..\r
\n" ); document.write( "\n" ); document.write( "5x^2+9y^2=720
\n" ); document.write( "divide by 720
\n" ); document.write( "x^2/144+y^2/80=1(standard form)
\n" ); document.write( "This is an ellipse with:
\n" ); document.write( "center (0,0),major axis horizontal because a>b
\n" ); document.write( "a^2=144
\n" ); document.write( "a=12
\n" ); document.write( "b^2=80
\n" ); document.write( "b=sqrt(80)
\n" ); document.write( "length of major axis,=2a=24
\n" ); document.write( "length of minor axis, 2b =2Sqrt(80)
\n" ); document.write( "..
\n" ); document.write( "x^2+9y^2-4x+54y+49=0
\n" ); document.write( "complete the squares
\n" ); document.write( "(x^2-4x+4)+9(y^2+6y+9)=-49+4+81
\n" ); document.write( "(x-2)^2+9(y+3)^2=36
\n" ); document.write( "(x-2)^2/36+(y+3)^2/4=1 (standard form)
\n" ); document.write( "This is an ellipse with:
