city begins with population of P_0 = 50,000 and has a growth rate of r = 15%

a) Find R and give the recursive formula. Use this to find P_1 and P_2

b) Give the explicit formula for P_N. What is P_11?

c) (bonus) find the time until the population reaches 950,000 (or more)

Exponential sequence explicit formula

, R = common ratio, r = growth rate

{ P_N = P_0 R^N, where R = 1+r is the common ratio, r = growth rate }

The per capita growth rate of many species varies temporally for a variety of reasons, including seasonality and habitat destruction. Suppose n(t) represents the population size at time t, where n is measured in individuals and t is measured in years. Solve the following differential equation. Habitat destruction is modeled as n' = (r − at)n      n(0) = n0. Here the per capita growth rate declines over time, going from positive to negative. It is modeled by the function r −...

A population of arctic birds has migrated farther north than previous years. The new location is good for the birds, and the population exhibits exponential growth. As time passes, the population begins to level out and maintain a steady population size. (10 points) Suppose that researchers say ? > 1. What does this mean? (1 point) In the first year, there are 200 births from an original population size of 2000. There are also 100 deaths, 10 emmigrants, and 20...

Carbon 14 is a radioactive isotope of carbon, the most common isotope of carbon being carbon 12. Carbon 14 is created when cosmic ray bombardment changes nitrogen 14 to carbon 14 in the upper atmosphere. The resulting carbon 14 combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis. Animals acquire carbon 14 by eating plants. When an animal or plant dies, it ceases to take on carbon 14, and the amount of isotope...
