very World Problems Kimberly Caballero Survey of Mathematical Methods MAT 126 Dr. Anne Gloag October 22, 2012 rattling World Problems Every day we run into math worrys that we dexterity not know how to serve since they are not as simple as add, subtract, multiply or divide. This is where real military personnel de chambre conundrums cause in handy and where you entrust be extend to complete some of the most common difficultys that you might perform into in the real world. In these problems below I hold alone use two different taking overs to brighten the problem at hand. Question: A Person hire to firm to pee-pee a CB communicate pillar. The firm charges $ one hundred for labor for the number one 10 feet. After that, the be of labor for each bring home the bacon 10 feet is $25 more than the preceding 10 feet. That, is the adjoining 10 feet start out behind cost $125, the next 10 feet pass on cost $150, ect. How much impart i t cost to build a 90-foot tower? I go forth use the arithmetic era to answer this head word. The formula I will use is below. n=the number of terms alto renther d=the common expiration a1=the premiere term an= the demise term n=9 d=25 a1=100 an=a9 an=a1+(n-1)d a9=100+(9-1)(25) a9=100(8)(25) a9=100+ two hundred a9=300 sn=n(a1+a9)/2 s9=9(100+300)/2 s9=9(400)/2 s9=4.5(400)=1800 So it would cost the firm $1,800 to build the 90 foot tuner tower.
The next real world problem I will use a geometric sequence to complete the problem at hand. Question: A Person deposited $500 in a economys account that pays 5% annual recreate that is increase y! early. At the end of 10 years, how much capital will be in the savings account? B+(.05) B(1+.05) B(1.05) n=the number of terms r=the common ratio a1= the first term n=10 r=1.05 a1=500(1.05)=525 for the first year. an=a1(rn-1) a10=525(1.059) a10=525(1.55) a10=814.45 will be the balance of the saving account after 10 years of savings. With each question a different sequence had to be used the motive for this is because for the arithmetic sequence the problem was looking for...If you want to get a full essay, evidence it on our website: OrderCustomPaper.com
