Question
The depth (in feet) of water at a dock changes with the rise and fall of tides. It is modeled by the function D(t)=5sin(6t76)+8,D(t)=5sin(6t76)+8, where
The depth (in feet) of water at a dock changes with the rise and fall of tides. It is modeled by the function
D(t)=5sin(6t76)+8,D(t)=5sin(6t76)+8, where tt is the number of hours after midnight. Determine the first time after midnight when the depth is 11.75 ft.
*** I think the answer is 7am but I'm not sure.
