The height h (in feet) of a water balloon can be modeled by h(x) = -3x^2 + 24x + 11, where x is the horizontal distance (in feet) from the launch pad.
\n" ); document.write( "The launchpad is adjusted so that the water balloon lands exactly 9 feet away from the launchpad.
\n" ); document.write( " Write a function that models the new path of the water balloon.
\n" ); document.write( ":
\n" ); document.write( "We should be able to do this by changing the coefficient of x^2 of the given equation:
\n" ); document.write( "x=9, y=0
\n" ); document.write( "a*(9^2) + 24(9) + 11 = 0
\n" ); document.write( "81a + 216 + 11 = 0
\n" ); document.write( "81a = -227
\n" ); document.write( "a = -227/81
\n" ); document.write( "a = -2.802
\n" ); document.write( "new equation
\n" ); document.write( "h(x) = -2.802x^2 + 24x + 11
\n" ); document.write( "
\n" );
