Joe runs 8.75 times around a track in 1, 125.803 seconds. If one lap around the track is 420.3 meters, which is the best estimate of the runner's average speed in meters per second (m/s)?

Anyone know? will mark brainliest if you're correct!

What is the effect on the graph of the function f(x)=x when f(x) is replaced with -f(x)+4

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)
