Algebra.Com's Answer #462950 by KMST(5328)![]() ![]() You can put this solution on YOUR website! The only constraint given is that the area fenced should be 2000 square feet. \n" ); document.write( "If this is not supposed to be realistic, x could be any positive real number. \n" ); document.write( "So the domain would be all the positive real numbers. \n" ); document.write( "It could be x=2000 feet, and then you would be fencing an area 1 foot by 2000 feet. \n" ); document.write( " \n" ); document.write( "We could make x=20,000 feet long and the fenced area width would be 0.1 foot=1.2 inches. \n" ); document.write( " \n" ); document.write( "As the width gets more ridiculously small, x could get as large as we want. \n" ); document.write( " |
