Algebra.Com's Answer #626554 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! The distance between the bases is the distance between the roots of the parabolic equation... \n" ); document.write( "Solving \n" ); document.write( "h=-0.00635x^2+4.0005x-0.07875 = 0 gives us \n" ); document.write( "x = 630 and x = .02 \n" ); document.write( "the distance is about 630 feet... \n" ); document.write( " |
