Answer 1

Answer:

  M(t) = 741·(1/2)^(t/5730)

Step-by-step explanation:

One way to write an exponential function is this:

  value at time t = (initial value) · (multiplier over period)^(t/period)

Here, the initial value is given as 741 grams, and the time period is 5730 years. The multiplier over that period is 1/2, since half of the quantity remains after that time. The problem statement tells us that "value at time t" is M(t), so we have ...

  M(t) = 741·(1/2)^(t/5730) . . . . . t in years; M(t) in grams
