Algebra.Com's Answer #594886 by lwsshak3(11628)![]() ![]() ![]() You can put this solution on YOUR website! 1.write an equation in standard form for the ellipse shown with center (0,0) , focus (0,6) co-vertex(0,-10).Given ellipse has a vertical major axis. (Note: focus and co-vertices cannot both be on the vertical major axis. I will assume you meant the co-vertex coordinates given are instead those of the vertex.)\r \n" ); document.write( "\n" ); document.write( "Its standard form of equation: \n" ); document.write( "center:(0,0) \n" ); document.write( "a=10 \n" ); document.write( "a^2=100 \n" ); document.write( "c=6 \n" ); document.write( "c^2=36 \n" ); document.write( "c^2=a^2-b^2 \n" ); document.write( "b^2=a^2-c^2=100-36=64 \n" ); document.write( "equation: \n" ); document.write( "\n" ); document.write( "2. The area of a rectangle is equal to x^2 +7x +10 square units. if the length of the rectangle is equal to x+5 units, what expression represents its width? \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "What expression represents its width? (x+2) \n" ); document.write( " |
