The path of a shell could be modeled by y=-0.0196x(squared) plus 1.137x where x was the horizontal distance traveled(in miles) and why was the height(in miles).How far could Big Bertha fire a shell? what was the shells maximum height?

Algebra.Com's Answer #171775 by Stitch(470)![]() ![]() ![]() You can put this solution on YOUR website! Given: \n" ); document.write( "Y is the height in miles. When Y = 0, the shell is on the ground. \n" ); document.write( "Solve for Y = 0 and that will give you the distance of the shot.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "Subtract .00196*X^2 from both sides \n" ); document.write( " \n" ); document.write( "Divide both sides by X \n" ); document.write( " \n" ); document.write( "Divide both sides by .00196 \n" ); document.write( " \n" ); document.write( "So the shell traveled 580 miles\r \n" ); document.write( "\n" ); document.write( "To find the max height of the shell, you need to see where the slope of the line equals 0. \n" ); document.write( "The derivative of the lines equation will give you the slope of the line.\r \n" ); document.write( "\n" ); document.write( "The equation for the line: \n" ); document.write( "Now take the derivative \n" ); document.write( " \n" ); document.write( "Set the equation equal to 0 to find the max height. \n" ); document.write( " \n" ); document.write( "Subtract -.00392 from both sides \n" ); document.write( " \n" ); document.write( "Divide both sides by .00392 \n" ); document.write( " \n" ); document.write( "Now we know that the maximum height occurs when X = 290 miles. \n" ); document.write( "Plug X 290 into the original equation \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
