Distance of a Dropped Ball from the Ground
The graph shows the distance from the ground, y, of a ball that is dropped from a 20-
meter height at different times, x, after the ball is dropped. Which statement about the
graph is true?

The height of the dropped ball decreases at an increasing
rate.
The height of the dropped ball decreases at a decreasing
rate.
The time the ball is in the air decreases at an increasing
rate.
The time the ball is in the air decreases at a decreasing
rate.

The length of triangle base is 26. a line, which is parallel to the base divides the triangle into two equal area parts. find the length of the segment between triangle legs.

What is the slope of the equation y =

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?
