Wednesday Warm- ups: Date:______
1.  Approximate 5(31.8) to the nearest hundredth.
A. 27.42 B. 29.16 C. 36.12 D. 32.90
2. A guest on a talk show tends to receive many phone calls right after she is on the show, and then the calls become less frequent. This can be represented by the equation y = 30(0.92)d, where y is the number of phone calls after d days. How many phone calls should she expect after a week?
A. 23 B. 17 C. 28 D. 2
3. Given the coordinates (0, 3), (1, 11), (2, 19), (3, 27), would a graph of these points exhibit exponential behavior?
A. yes, exponential and linear behavior B. no, it would display linear behavior C. no, it would not display exponential or linear behavior D. yes, exponential behavior only
Thursday Warm- ups: Date:______
1.  If one person does good deeds for three new people, then the three new people each do good deeds for three more new people. Next, nine people each do good deeds for three more new people, and so on. Does this situation represent a linear or exponential model? Why or why not?
2.  Describe the similarities and differences of a linear and an exponential NOW- NEXT equation.
3.  Town A adds 10 people per year to its population, and town B grows by 10% each year. In 2006, each town has 145 residents. For each town, determine whether the population growth is linear or exponential. Explain. Report the constant rate per unit interval (linear) or the constant percent rate per unit interval (exponential).
Friday Warm- ups: Date:______
You just got a pair of baby rabbits for your birthday – one male and one female. You decide that you will breed the rabbits, but need to plan a budget for the upcoming year. To help prepare your budget, you need an estimate of how many rabbits you will have by the end of the year. In order to build a mathematical model of this situation, you make the following assumptions:
·  A rabbit will reach sexual maturity after one month.
·  The gestation period of a rabbit is one month.
·  Once a female rabbit reaches sexual maturity, she will give birth every month.
·  A female rabbit will always give birth to one male rabbit and one female rabbit.
·  Rabbits never die.
So how many male/female rabbit pairs are there after one year (12 months)?
