Earches related to n crescent moon bay in july, high tide is at 3: 00 pm. the water level is 6 feet at high tide and 2 feet at low tide. assuming the next high tide is exactly 12 hours later and the height of the water can be modeled by a cosine curve, find an equation for crescent moon bay's water level in july as a function of time (t).

i got f(t) = 4 cos pi over 6 t + 2 for my answer

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.

The distance between the first bird and the bird watcher is 30 feet, hope this . : )
