Population growth Using discrete time steps, which is easier to describe that continuous change, the model for population growth is this: Nt = N0 x rate^t. r: 10 Time step (t) (Nt) Population at end of time step (Nt) N0: 2 0 N0 2 1 N1 20 2 N2 200 3 N3 2000 4 N4 20000 5 N5 200000 6 N6 2000000 7 N7 20000000 8 N8 200000000 9 N9 2000000000 10 N10 20000000000 Try these hypothetical "r" values to begin, then try new numbers of your own: Moose: 1.5 Wolf: 1.2 Rabbit: 5 House fly: 80 Cockroach: 40 Endangered tiger: 0.8 What do N0 and N1 means? what does an r of ''10'' represent what value of r makes the graph extremely steep

A particular region has a rabbit population of 1600. Two foxes are introduced to control the population of rabbits. Following this, the number of rabbits decreases according to the formula R(t) = 1700 - Ae^{kt}, where A and k are constants, and R(t) is the number of rabbits in the region t years after the introduction of the foxes. (a) Given that the population of rabbits drops by one quarter after 5 years, find the values of A and k. (b) Following this model, how long will it take for the rabbits to become extinct? Give your answer to two decimal places. (c) Let F(t) be the number of foxes in the region t years after their introduction. If dF/dt = 0.7F(t), find the time at which the rate of decrease of the rabbit population is equal to the rate of increase of the fox population, correct to two decimal places. Hint. Note that dR/dt and dF/dt represent the rates of change of the rabbit and fox populations respectively. (d) Identify any problems with this model.

Population Growth Many biological populations, both plant and animal, experience seasonal growth. For example, an animal population might flourish during the spring and summer and die back in the fall. The population, $f(t),$ at time $t,$ is often modeled by $$f(t)=f(0) e^{c \sin (t)}$$ where $f(0)$ is the size of the population when $t=0$ . Suppose that $f(0)=1000$ and $c=2 .$ Find the functional values in parts (a) $-(\mathrm{d})$ . $$\begin{array}{l}{\text { (a) } f(0.2) \quad \text { (b) } f(1) \text { (c) } f^{\prime}(0) \quad \text { (d) } f^{\prime}(0.2)} \\ {\text { (e) Use a graphing calculator to graph } f(t) \text { on }[0,11] \text { . }} \\ {\text { (f) Find the maximum and minimum values of } f(t) \text { and the }} \\ {\text { values of } t \text { where they occur. }}\end{array}$$
