Calculus Lab Write-up Week 10 Population Curves Include your name and the names of the people in your group on your lab write-up. Each person will submit their own lab write-up, saved as a PDF to the online system. 1. (80 points) Demonstrate and Explain: Clearly and thoroughly explain your answers to these questions based on the work you did with your group on labs this week. These questions refer to Lab 10A: Population Curves. Recall, the world population in 1999 was approximately Po = 6.067 billion people. In 2000, it was approximately Pi = 6.145 billion people. (a) (Parts la 8 2a) Show how to model the world population with an exponential curve, P(t) (including how you find the value of To), and with a logistic growth curve, L(t) (where K = 15 and ro = 0.022.) (b) (Parts 1b & 2b) Create an accurate, well-labeled graph that shows the world populations predicted by both P(t) and L(t) from 1999 to 2049. (c) (Parts 1d 8 2d) According to each of these models, how fast (in billions of people per year) is the world population growing in 2019? In 2049? Show very clearly how you are finding these solutions. (d) (Part 3) Compare the two models P(t) and L(t). As t gets large (e.g. the year 2099), what do P'(t) and L'(t) tell you about how each of the models is growing? Which of these models do you find more realistic? Explain your reasoning. 2. (10 points) Summarize: What do you think are the big ideas for calculus in the week 10 lab? What you want to remember from your work on this lab? Be sure to include definitions or examples of important vocabulary related to population growth and the use of the derivative function in this context. 3. (10 points) Reflect: Write a short reflection (4-5 sentences or more) on how working on the week 10 labs went for you. . What questions do you still have about modeling exponential growth that you would like to discuss more? . What worked well in collaborating with the members of your group? What could have gone better? . What could you try doing for the next lab to improve your learning?Week 10A Population Curves The world population in 1999 was approximately Po = 6.067 billion people, and in 2000, it was approximately P1 = 6.145 billion people.! In this activity, we'll compare different mathematical ways of modeling the world population (and, along the way, we'll practice the chain rule). 1. Exponential Growth Model. Let's assume that the world population is growing exponen- tially. To do this, we will let P(t) denote the world population (in billions of people) in year t, where t = 0 represents the year 1999. An exponential growth model would say P(t) = Poerot, where Po is the number defined above and ro is some number yet to be determined. (a) Use the information given above to determine To, and use that to write P(t) explicitly. (b) Using a computer graphing program (or graphing calculator), graph P(t) for 0
