A stunt diver jumps from the top of a 40-meter platform. The diver's height above the water can be modeled by the function h=-5t^2+10t+40, where h is height in meters and t is time in seconds. Find the time it takes the diver to reach the water.
\n" ); document.write( "----------
\n" ); document.write( "He reaches the water when h = 0
\n" ); document.write( "h=-5t^2+10t+40
\n" ); document.write( "-5t^2+10t+40 = 0
\n" ); document.write( "-----
\n" ); document.write( "Solve for t
\n" ); document.write( "Ignore the negative solution.
\n" ); document.write( "
