The water depth "d" for the Bay of Fundy can be modeled by,
d=35-28cos(π)/(6.2)t
where "d" is measured in feet and "t" is the time in hours. If t=0 represents midnight, at what time(s) is the water depth 7 feet?
***
d=35-28cos(π)/(6.2)t
cos(π)=-1
t=35-28cos(π)/(6.2)d
t=35-28cos(π)/(6.2)*7
t=(35+28)/43.4=1.45
what time is the water depth 7 feet? 1.45 hrs after midnight or 1:27 AM
