Hello, this is for my calc3 exam review, i don't know how to do this. can someone me out plz?

a lamina occupies the region inside the cardioid r = 1 + cos θ and outside the circle x 2 + y 2 = 9/4. the density at each point is inversely proportional to the distance to the y-axis. find the center of mass of the lamina. you may use symmetry where appropriate.

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.

25/6 hope it : )

step-by-step explanation:

8*8*8*8*8*8*8*8*8*8*8*8=68719476736

10 - 8 = -2

  8 - 6 = -2

etc, so -2 is the common difference
