1)Find the foci of an ellipse with the equation
\n" ); document.write( "7(x - 2)2 + 3(y - 2)2 = 21
\n" ); document.write( "(x - 2)^2/3 + (y - 2)^2/7 = 1
\n" ); document.write( "a = 7
\n" ); document.write( "b = 3
\n" ); document.write( "\"c%5E2+=+a%5E2+-+b%5E2\"
\n" ); document.write( "\"c%5E2+=+49+-+9\"
\n" ); document.write( "\"c+=+2%2Asqrt%2810%29\"
\n" ); document.write( "Vertical ellipse, so the increasement is due to 'y'
\n" ); document.write( "Center: (2,2)
\n" ); document.write( "Foci: (2,2+\"2%2Asqrt%2810%29\") and (2,2-\"2%2Asqrt%2810%29\")
\n" ); document.write( "2)Find the slopes of the asymptotes of a hyperbola with the equation
\n" ); document.write( "y^2 = 36 + 4x^2
\n" ); document.write( "y^2 - 4x^2 = 36
\n" ); document.write( "y^2/36 - x^2/9 = 1
\n" ); document.write( "Vertical hyperbola, so the slope of the asymptotes = +- a/b
\n" ); document.write( "a = 36 and b = 9
\n" ); document.write( "Slope = +- 36/9 = +- 4
\n" ); document.write( "3)What is the graph of the equation
