Use the result of Exercise 9 to make a conjecture about the change in the center of mass when a lamina of constant density is translated c units horizontally or d units vertically. Is the conjecture true when the density is not constant? Explain.

Data from in Exercise 9

Find the mass and center of mass of the lamina for each density.

R: square with vertices (0, 0), (a, 0), (0, a),(a, a)
