Question

Please help -
In Panama City in January, high tide was at midnight. The water level at high tide was 9 feet and 1 foot at low tide. Assuming the next high tide is exactly 12 hours later and that the height of the water can be modeled by a cosine curve, find an equation for water level in January for Panama City as a function of time (t).

I don't know what the formula for a cosine curve is, nor am I aware of the meanings of each part. Multiple choice answers are below:

That is a huge hint. Answer this and we'll go forward.
