The length of a water wave close to land depends on
several factors, one of which is the depth of the water. However, the length, L (in
meters), of deep-water waves (those far away from land) can be approximated by 
where s is the speed of the wave in meters per second. Find the length of a deep-water
wave that has a speed of 9 meters per second. Round to the nearest tenth of a
meter.
a. | 51.9 meters | d. | 62.3
meters | b. | 57.7 meters | e. | 33.3
meters | c. | 26.0 meters |
