The function f(t) = 3 cos(pi over 6t) + 5 represents the tide in blastic sea. it has a maximum of 8 feet when time (t) is 0 and a minimum of 2 feet. the sea repeats this cycle every 12 hours. after nine hours, how high is the tide?

Explain how you can use the associative property to evaluate (7x50)x4.

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
