2. At the end of a dock, the high tide of 14 m is recorded at 9:00 am.
The low tide of 6 m is recorded at 3:00 pm. A sinusoidal function can model the water depth versus time.

b) Construct a model for the water depth using a sine function, where time is measured in hours past high tide.

what is the phase shift?

How about, rather than spamming the chat with requests commanding people to help you with this question, you instead write out what work you've done on the question so far, so that we can actually help you? That would be far more helpful than just asking people to solve this question for you.

ok fine 
alright so i got amplitude = 4 
The period = 30
and the vertical displacement = 10 
now using all this how do you expect to find phase shift
