3. anika is on the crew to set up rides for the state fair. the crew does most of the setup on the day that the fair arrives at the fairground and then continues to work on finishing the setup for about a week to have the rides ready to go in time for the opening of the fair. the scatter plot shows anika's setup time on different days and the linear model for the data.

(a) what is the equation of the line, written in slope-intercept form? show how you determined the equation.
(b) based on the linear model, predict how long anika worked on the setup crew on the day the fair arrived at the fairgrounds, day 0. approximately how much did her setup time decrease per day?

The school track has eight lanes. each lane is 1.25 meters wide. the arc at each end of the track is 180. the distance of the home straight and the radii for the arcs in the 1st 4 lanes are given. s=85m r1=36.5m r2=37.75m r3=39m r4=40.25m part one: find the radii of lanes 5 through 8 of the track. show your work. part two: if max ran around lane one, how far did he run? show your work and explain your solution. part three: max wants to run a total of three laps around the track, choose two additional lanes (2-8) for him to run and find the distance around those two lanes. show your work and round to the hundredths. part 4: based on your lane choices in part three, what was the total distance max ran in the three laps around the track?
