POPULATIONS: Population growth is a ____________________________________ because it represents change over time. CONTINUOUS GROWTH: the dynamics of change are in effect_______________________ DISCRETE GROWTH: ____________________________ (stop and go) where there is a ____________ change in the population after a certain amount of time with no change to population TRANSITION: _____________________________of time between changes to population. Example: Basic Questions of population growth: What will happen to a given population over time? What are the long-term patterns of growth (if any)? TRANSITION RULES: rules that govern the transition WHEN does change happen HOW is the population changed POPULATION SEQUENCE: a list of numbers that represents the changes to population over multiple transitions or generations. Generic Population Sequence = P0, P1, P2, P3, , PN, P = N (subscript) = Example: The number of cars produced is expected to increase by 25 every 2 months. If the company started with 100 cars find the population sequence. Transition = Transition Rule = Generation/ Transitions (N)N = 0N = 1N = 2N = 3POPULATION (PN)P0 = Initial Population (SEED) P1 = population of 1st generation P2 = population of 2nd generation P3 = population of 3rd generation  The transition rule is not sustainable over the long hall. Our goal is to best model the growth of population, but no model is exact to nature or the real-life. Section 10.2: Linear Growth Arithmetic Sequences Part 1 Linear Growth Model: population changes (increases or decreases) by a constant amount each transition. Example Problem: A city is considering a new law to restrict the monthly amount of garbage allowed into the local landfill to a maximum of 120 tons a month. Although there is currently only 8000 tons of garbage in the landfill, there is a concern that the landfill will reach its maximum capacity of 20,000 tons. Determine the transition and transition rule of this growth problem.  Transitions: Transition Rule: Write the population sequence: Plot and connect the points of the sequence. What type of graph is created? How much garbage will there be in the landfill five years from now? (Hint: How many transitions represent 5 years) How long before the landfill reaches its 20,000-ton capacity? Linear growth model produces an _____________________________ SEQUENCE. Definition: the DIFFERENCE between consecutive terms is constant (add or subtract constant) The constant amount of change is called the ______________________________________, d.

Assume the money remains untouched in the account. The seed is given by the original investment or principal and the common ratio r is derived from the interest rate, r = 1 + interest rate. Annual Interest Formula: P0 = principal or initial investment/ population N = number of years i = annual interest rate (decimal) Example #1: Suppose you invest $367.51 in account that pays an annual interest rate of 4.5% a year and you let the money grow. How much money will there be in the account at the end of 7 years? What if you leave the money in the account for 7.5 years?

How much additional money would you gain by leaving it in the account for one more year? Example #3: Suppose you invest $3420 in an account paying 7.5% annual interest. Suppose in 5 years the annual interest rate will drop to 5.5 and you keep the money in the account for an additional 3 years. How much money do you have in the account at the end of the 8-year period? How much money did you lose out on in the last 3 years of your account? Example #4: Suppose you invest $4000 in an account paying 6% annual interest. Suppose in 6 years the annual interest rate will drop to take out $1500 and leave the leftover money untouched for another 4 years. a) How much money do you have in the account at the end of the 10-year period? b) How money would you have had if you didnt need that $1500 after 6 years but after 10 years?

If we dont touch the money how much money will there be in the account at the end of 1 Year 4 years 4.5 years 20 years DAILY COMPOUNDED INTEREST: A principal of $1500 in an account that pays 8% annual interest compounded daily. If we dont touch the money how much money will there be in the account at the end of 1 Year 2 years 8 years 16 years ANNUAL YIELD: TOTAL AVERAGE PERCENT INCREASE of an investment over a one-year period. Annual Yield and Annual Interest Rate are not always the same percentage. Example: Determine the annual yield if you began the year with $2400 and ended 1 year later with $2784. For example, you invest $1000 at an annual interest rate of 5%.
