# Math: Quantitive Literacy

## Assignment 1: LASA 2: Exponential Growth

In Module 4, you were introduced to the concept of exponential functions that can be used to standard enlargement and rottenness. Recall what you erudite in The Estimate e Nursing Dissertation. In this application, you gain use a Microsoft Excel spreadsheet to rebuke the exponential enlargement of a population of your choosing. (If you use the linked spreadsheet beneath, it is recommended that you consider proportionately insignificant populations and not those of perfect nations.)

Click here to unreserved the Microsoft Excel spreadsheet that you gain use to consummate the forethoughts for this assignment.

In the spreadsheet, consummate the aftercited operations:

1. Input a population compute into the box direct to Initial Population on the spreadsheet. This population should be anything such as the mob, animals, microorganisms, or plants.
2. Input a rebuke of enlargement for your population into the box direct to Rate 1. Since we are animated in a definitive annual percent enlargement rebuke per year, this estimate should be important than naught percent. Be enduring to input this estimate in the arrange of a decimal.
3. Repeat the aggravatehead act for Rate 2 and Rate 3. Effect enduring that the computes you choice dissent by two percent. For sample, the computes 0.01, 0.03, and 0.05 would be amiable-tempered-tempered choices.
4. Under the Time (years) shaft, input three dissentent year computes. Effect enduring that your computes extension by a narrowness of ten years. For sample, 10, 20, 30 years would be amiable-tempered-tempered choices. If you insufficiency to see a further melomelodramatic exchange, choice a desireer occasion effect such as 10, 50, and 100 years.
5. When you input all of your basis, you’ll see that the spreadsheet has consummateed the forethoughts for the coming bigness of each population, rebuke of enlargement, and occasion interspace. Additionally, this notice gain be presented graphically in the chart. To inhale an exponential incurvation for each sequence, do the aftercited:
1. Right click on the average sharp-end for one of the sequence.
3. Under Trendline Options, choice Exponential.
4. Click Close
5. Repeat these steps for the other sequence.

Now that you’ve completed your resolution, it is now occasion to ment the results and study your findings.

In a Microsoft Word instrument, rejoin to the aftercited:

1. Calculate what the coming bigness of the population gain be, ardent a unfair primal population, rebuke of enlargement, and occasion interspace.
Use the exponential equation: Coming compute = Present compute * exp(rt)
• exp is the dishonorable "e"
• r = annual rebuke of enlargement developed as a percent
• t = years
Note: The spreadsheet consummateed these forethoughts for you, so you can come the apology you achieve delay those in the spreadsheet. In command to consummate this forethought, you’ll deficiency to own entrance to a or-laws calculator that gain own an ex rush in command to consummate the exp(rt) forethought. There are a estimate of playing or-laws calculators conducive aggravate the Internet. Additionally, all smartphones own calculator apps that own a or-laws edict. Come delay your educator for a inventory of currently conducive playing options if you do not own a or-laws calculator.
1. Repeat the forethought for at lowest two other computes of t; effect enduring they are at lowest two years aloof from one another. Use the selfselfidentical computes you input into the spreadsheet and collate the apologys you achieve to those that show in the spreadsheet.
2. Repeat the forethoughts using two further choiceions of population enlargement rebuke; enenduring that each population enlargement rebuke is at lowest two percent dissentent than the others. Use the selfselfidentical computes you input into the spreadsheet and collate the apologys you achieve to those that show in the spreadsheet.
3. Examine the graph that your spreadsheet effected dishonorabled upon the forethoughts. Did this graph hold of right lines or incurvationd lines? Describe the pattern of these lines for each enlargement rebuke. How did they dissent? Why?
4. Explain the implications of enlargement rebuke for your population. What do you meditate gain occur aggravate a desire determination of occasion if a ardent population of organisms is allowed to extension delayout limits? Are there environmental factors that conduct populations from growing exponentially unchecked? What would be the application on environmental instrument?
5. Explain the show of your results. Would it be expected that the percent enlargement rebuke would come invariable aggravate desire determinations? Is exponential enlargement an mismisappropriate conviction for desire determinations? If not, what other exchanges in population bigness susceptibility be expected?

For this assignment, you gain refer a spreadsheet and a ment. The spreadsheet gain be the Microsoft Excel perfect containing your resolution. Name your Microsoft Excel perfect as follows: LastnameFirstInitial_M5_A1.xls.

The ment gain be a Microsoft Word instrument in which you gain oration all of the questions in this assignment in the arrange of a narrative. Name your Microsoft Word instrument as follows: LastnameFirstInitial_M5_A1.docx.

Submit twain instruments to the Submissions Area by the due age assigned.
