You have just won the grand prize in a lottery. The lottery commission tells you that you may choose from one of two cash prizes: Either Option 1: $1,000 per day for 30 days Option 2: $0.01 (one penny) the first day, $0.02 the next day, $0.04 the next day....for 30 days. Each day's pay is double the pay from the previous day. Which would you choose? Answer by entering the expressions in Maple below to represent amount of money for each at the end of 30 days. Option 1: Income would be: JSFH Option 2: Income in pennies would be: JSFH Therefore you choose: Answer:

Linear growth occurs over time has a constant amount each unit of time. Therefore when we graph the growth as a functuon of time, we have a straight line graph. The first option for the lottery represents linear growth. The slope of linear graph represents this change per unit of time (in the above example the slope is $1000). With linear growth, the formula for quantity Q at time t is given by: 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 where Q0 is the initial quantity, and r constant amount of increase per unit of t.

The boom in population growth today began with the Industrial Revolution (See Section 8C of your text for more information). http://opr.princeton.edu//popclock/ The following link takes us to the United States Census Bureau's data about world population growth. http://www.census.gov/ipc/www/idb/ We can see from the charts that the growth rate r is in fact not a constant value and has in fact been declining. Using the chart on World Population Growth Rates, estimate the population growth rate (as a decimal) for the year 2009. Then use that in the population formula to estimate the population in 2050.

Exercises: 1. When I went to the local movie theater as a child, I took 25 cents -- 15 cents to get in the movie, 5 cents for popcorn, 5 cents for coke or candy bar.

If r is negative the we have exponential decay (declining values for Q). Example: China's Goal for Declining Population. China has a goal of reducing its population to 700 million by 2050. In the year 2000 (treating this as our starting year), the population was 1.2 billion. Will a rate of decline of -0.5% allow them to reach their goal? When will they reach their goal of 1.2 billion with this rate of decline?
