document.write( "Question 1122767: The height of waves in a storm, measured from the base of the trough, depends on the speed of the wind. Assuming that the wind has no obstructions for a long distance, the maximum wave height H for a wind speed x can be approximated by H=0.02x2+0.2x−37, where H is in feet and x is in knots (nautical miles per hour). For what wind speed would the maximum wave height be 3 ft? \n" ); document.write( "
