A skier starts at an altitude of 2,500 feet. She descends going 4.5 feet per second. She stops to take a rest at an altitude of 2,430.25 feet. Which equations could be used to solve for how many seconds have passed before she stops to take a break? Select all that apply. A: 2,500 + 4.5s =2,430.25
B:2,500 - 4.5s =2,430.25
C:2,430 +4.5s =2,500
D:2,430 - 4.5s = 2,500

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)
