document.write( "Question 1052592: henry jumps from a platform 10 meters above the surface of the water. the height of henry's jump can be modeled by the function h(t) = -5.3t^2 + 4.8t +10, where t is time in seconds after the jump. At what time t is henry 3 meters above the water? \n" ); document.write( "

h(t) = -5.3t^2 + 4.8t +10
\n" ); document.write( "-----
\n" ); document.write( "h(t) = -5.3t^2 + 4.8t +10 = 3
\n" ); document.write( "Solve for t
