Question

One of the byproducts of nuclear power generation is Uranium-233. Uranium is decaying at a constant 57% rate per day. If 3,820 pounds are produced from a power plant, what will the amount be in 15 days? 0.0739 19,737,001.91 19,737,001 0.739

Answer 1

Answer:

is 0.739

Step-by-step explanation:

Answer 2

Given that the decay rate of the uranium is given to be 57%, this means that on the second day only 43% of the Uranium-233 will be left. The equation therefore, that will allow us to answer the question is that,
                                   A(t) = A(0)(1 - r)^n
where A(t) is the amount after n days, A(0) is the original amount, r is the decimal equivalent of the rate and n is the number of days. Substituting the known values,
                                  A(t) = (3,820 pounds)*(1-0.57)^15
                                   A(t) = 0.0121 pounds
This is unfortunately not found in the choices.
