Use the image below to answer the following question: A right triangle is shown. The two angles that are not 90 degrees are marked x and y. The leg across from angle y measuring 9, another leg across from angle x measuring 12, and the hypotenuse measuring 15. What relationship do the ratios of sin y° and cos x° share? The ratios are both identical. (9 over 15 and 9 over 15) The ratios are opposites. (negative 9 over 15 and 9 over 15) The ratios are reciprocals. (9 over 15 and 15 over 9) The ratios are both negative. (negative 15 over 9 and negative 9 over 15)

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)
