The measurement of radioactive decay can be useful tool in things such as carbon-dating. for a carbon sample with mass 500kg and a half life of 5,730 years, calculate the remaining mass after 20,000years.

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

Multiply and simplify. 2x^2 y^3 z^2 · 4xy^4 x^2 i will mark you brainliest if right. show how you got the answer, !

Find the distance of the blue line between the two labeled points. round to the nearest hundredth. a) 7.07 b) 7.21 c) 10 d) 5.12
