Find the volume of the solid s whose base is the triangular region in the x y-plane with vertices (0,0), (1,0), and (0,1) and such that cross-sections perpendicular to the x-axis are squares.

Suppose a laboratory has a 30 g sample of polonium-210. the half-life of polonium-210 is about 138 days how many half-lives of polonium-210 occur in 1104 days? how much polonium is in the sample 1104 days later? 9; 0.06 g 8; 0.12 g 8; 2,070 g
