Sketch a graph of the following - at midnight the water at a particular beach is at high tide. at the same time a gauge at the end of a pier reads 10 feet. low tide is reached at 6 am when the gauge reads 4ft.

            In the attachment is a graph of the cosine function that represents changing of the tide.
            y max = 10 ft  at midnight
            y min = 5 ft at 6 AM

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
