Let r denote the region in the first quadrant that is bounded by the y-axis, y = 2x, and is between and x^2 + y^2 = 1 and x^2 + y^2 = 2. suppose that the mass density at each point in r is inversely proportional to its distance from the origin. a. sketch r b. set-up double integrals in polar coordinates that equal the area of r, the mass of r, and the y-coordinate of the center of mass of r.

When only separate discreet points are graphed it is called?

Miguel’s teacher asks him to color 4/8 of his grid. he must use 3 colors: red, blue, and green. there must be more green sections than red sections. how can miguel color all the sections of his grid to follow all the rules

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?
