- Buffalo: Waterton Lakes National Park of Canada, where the Great Plains dramatically meet the Rocky Mountains in Alberta, has a migratory buffalo bison herd that spends falls and winters in the park. The herd is currently managed and so kept small; however, if it were unmanaged and allowed to grow, then the number N of buffalo in the herd could be estimated by the logistic formula N=3151+14e0.23t Here t is the number of years since the beginning of 2002, the first year the herd is unmanaged. a. Make a graph of N versus t covering the next 30 years of the herds existance corresponding to dates up to 2032. b. How many buffalo are in the herd at the beginning of 2002? c. When will the number of buffalo first exceed 300?. d. How many buffalo will there eventually be in the herd? e. When is the graph of N, as a function of t, concave up? When is it concave down? What does this mean in terms of the growth of the buffalo herd?.arrow_forwardWeight Gain Zoologists have studied the daily rate of gain in weight G as a function of daily milk energy intake M during the first month of life in several ungulate that is, hoofed mammal species. Both M and G are measured per unit of mean body weight. They developed the model G=0.067+0.052logM With appropriate units for M and G. a.Draw a graph of G versus M. Include values of M up to 0.4unit. b.If the daily milk-energy intake M is 0.3unit, what is the daily rate of gain in weight? c.A zookeeper wants to bottle-feed an elk calf so as to maintain a daily rate of gain in weight G of 0.3unit. What must the daily milk-energy intake be? d.The study cited above noted that the higher levels of milk ingested per unit of body weight are used with reduced efficiency. Explain how the shape of the graph supports this statement.arrow_forward
