The high tides occur when , the height H(t) attains maximum value , that is the time when sine function become maximum .
Sine function attains maximum value at 
So high tides occur after 3.415 hours from midnight , that is at time of about 3 hour , 0.415×60 minutes , we get time as approximately ,
3:24:54 AM or 3:25 AM

A certain bay with very high tides displays the following behavior. In one 12-h period the water starts at mean sea level, rises to 19 ft above, drops to 19 ft below, then returns to mean sea level. Assuming that the motion of the tides is simple harmonic, find an equation that describes the height of the tide in this bay above mean sea level. (Let y be the height above sea level in...

4) A cylindrical can (radius 10 millimeters) is used to measure rainfall in Stormville. The can is initially empty and rain enters the can during a 60-day period. The height of water in the can is modeled by the function S, where S(t) is measured in millimeters and t is measured in days for 0sts 60. The rate at which the height of water is rising in the can is given by S'(t) = 2 sin(0.03t) of the 60-day period?...

What an Executive Summary Is
An executive summary is a specific type of document that does
two things: it summarizes a research article, and it offers
recommendations as to how information from the article can be
used.
Some long reports can contain an executive summary section, as
indicated in the Pearson handbook.
