Find the standard form of the equation of the ellipse with the given characteristics and center at the origin.\r
\n" ); document.write( "\n" ); document.write( "\"x%5E2%2Fa%5E2%2By%5E2%2Fb%5E2=1\"\r
\n" ); document.write( "\n" ); document.write( "center is at (\"0\",\"0\")\r
\n" ); document.write( "\n" ); document.write( "Foci: (\"5\",\"+0\"), (\"-5\", \"0\")\r
\n" ); document.write( "\n" ); document.write( "focus is \"5\" units from the center, so \"c+=+5\" and \r
\n" ); document.write( "\n" ); document.write( "major axis of length \"2a=14\"->\"a=7\"\r
\n" ); document.write( "\n" ); document.write( "use the equation \"b%5E2+%2B+c%5E2+=+a%5E2\" to find \"b%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"b%5E2++=+a%5E2-c%5E2\"
\n" ); document.write( "\"b%5E2++=+7%5E2-5%5E2\"
\n" ); document.write( "\"b%5E2++=+49-25\"
\n" ); document.write( "\"b%5E2++=+24\"\r
\n" ); document.write( "\n" ); document.write( "your equation is:\r
\n" ); document.write( "\n" ); document.write( "\"x%5E2%2F49%2By%5E2%2F24=1\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \r
