The quadratic function that models the height, in feet, of the ball after t seconds is p(x)=-16tē+46t+6 How long does it take for the ball to hit the ground?
\n" ); document.write( "------------
\n" ); document.write( "I think it's p(t)=-16tē+46t+6 since there's no x on the right side.
\n" ); document.write( "---
\n" ); document.write( "p(t)=-16tē+46t+6
\n" ); document.write( "When it hits the ground, p(t) = 0
\n" ); document.write( "----
\n" ); document.write( "-16tē+46t+6 = 0
\n" ); document.write( "Solve for t.
\n" ); document.write( "Use the positive value. \n" ); document.write( "
\n" );
