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.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
