Algebra.Com's Answer #597020 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! The vertex is 4 units from the center and the minor axis is 2 units long, so the semi-minor axis is 1 unit.\r \n" ); document.write( "\n" ); document.write( "a^2 will be 16 and b^2=1\r \n" ); document.write( "\n" ); document.write( "{(x+1)^2/16} + {(b-3)^2)/1}=1\r \n" ); document.write( "\n" ); document.write( "a^2-c^2=b^2 \n" ); document.write( "16-c^2=1 \n" ); document.write( "c^2=15 \n" ); document.write( "c= +/- sqrt (15).
