7.22. Let $R$ be a ring, let $P \subset R$ be a prime ideal, let $S = R \setminus P$ be the complement of $P$, let $R_S$ be the localization ring as described in Exercise 7.21, and let $Q = \{(a, b) \in R_S : a \in P\}$. Prove that $Q$ is the unique maximal ideal of $R_S$. (A ring with a unique maximal ideal is called a local ring; see Exercise 3.53.)

5. (12 points) The activity of a certain sample of radioactive material is measured to be 3.68x10$^8$ decays/sec at 11:30 am. The activity is measured again an hour and a half later (1:00 pm) to be 2.21x10$^8$ decays/sec. a. What is the decay constant for this material? b. What is the half life of this material? c. How many radioactive atoms were in the initial sample? d. What will the activity be at 10:00 pm that same day? a) 2.21x10$^8$ = 3.68x10$^8$ e$^{-2(5400)}$ $\ln(\frac{2.21x10^8}{3.68x10^8}) = -\lambda(\frac{5400}{5400})$ 5400 $\lambda = 9.44298x10^{-5}$ units?
