Step 1
Step 1: The decay rate is constant, so after 5200 seconds, the decay rate will still be 10,000 decays per second. Show more…

If the half-life of a radioactive substance is 5,200 years, then at what rate is it decaying? (Hint: The amount goes from A0 to 1/2A0 in 5,200 years. The decay rate, k, is __ rounded to six decimal places as needed.

A certain radioactive substance decays exponentially over time. The amount of a sample of the substance that remains, P, after t years is given by P(t) = 10e^-4t, where P is expressed as a percentage. a. At what time has 50% of the substance decayed? (5 marks) b. Determine the rate of change of the function. (2 marks) c. What is the rate of decay when 50% of the original sample has decayed? (2 marks)
