8. find the period and amplitude of the function. y=5cos2theta period: pi, radians; amplitude: 2.5 period pi, radians; amplitude: 5 period 2pi, radians; amplitude 2.5 period 2pi, radians; amplitude 5 if anyone knows the rest of the test that would be amazing for this 18 question test.

The graph below represents the number of dolphins in a dolphin sanctuary. select all the key features of this function.

Find the difference (8ab+a+2) - (3ab+6)

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)
