The graph shows the vertical position of a ball attached to a spring oscillating between a low point and a high point as a function of time. Select all statements that describe the graph.
The ball travels 24 cm in 1 s.
The amplitude is 24 cm.
The midline is at f(x)=0.
It takes the ball 2 s to complete a cycle.

Mary used 1/7 of a spool of ribbon to complete 4 projects. she used the same amount of ribbon on each project. how much ribbon did she use on each project?

Plot the points (0,6), (3,15.8), and (9.5,0) using the graphing tool, and find the function

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)
