A= k· A1. The radioactive isotope lead, Pb-209, decays at a rate proportional tothe amount present at time t and has a half-life of 3.3 hours. If 1.5grams of this isotope is present initially, answer the following:a) Find the complete model. A(t) = A₁ektb) How long will it take for 30% of the lead to decay?(Round to the tenths place.)c) How much lead is present after 5 hours?(Round to the hundredths place.)d) At what rate is the lead decaying after 5 hours?(Round to the hundredths place.)

A tree farm starts with eight trees. Tree growth is expected to follow logistic growth with a first order growth rate constant of r = 0.15 yr–1 to a maximum of 6,000 trees. A. Write the equation that relates the number of trees (N) to time (t). What are the values of N0, r, and K? B. Plot the number of trees over time if no harvesting occurs. Go out to about 80 years. C. What is the maximum sustainable yield (MSY)? How long should you wait before harvesting at the MSY? D. What is the standing crop? (The standing crop is the number of trees at steady state when harvesting at the MSY.)
