Question 1131110: Question:
The half-life of radium-223 is approximately 1143 years. Use the formula A(t)=A_0 a^t to determine a and write a general formula, in the form A(t)=A_0 a^t, that describes the amount of radium-223 left after t years, where A_0 is the amount of radium-223 at time t=0. Round a to six decimal places.
