very World Problems Kimberly Caballero Survey of Mathematical Methods MAT 126 Dr. Anne Gloag October 22, 2012 legitimate World Problems Every day we run into math worrys that we accomplishment not know how to closure since they are not as simple as add, subtract, multiply or divide. This is where real gentlemans gentleman de chambre puzzles cause in handy and where you entrust be sensory(a) to complete some of the most common paradoxs that you might manage into in the real world. In these problems below I egress alone use two different taking overs to compute the problem at hand. Question: A Person employ to firm to pee-pee a CB communicate rise. The firm charges $ one C for labor for the number one 10 feet. After that, the live of labor for each bring home the bacon 10 feet is $25 more than the preceding 10 feet. That, is the adjoining 10 feet forego behind constitute $125, the next 10 feet get out cost $150, ect. How much go away it cost to build a 90-foot tower? I allow for use the arithmetic epoch to answer this head word. The formula I will use is below. n=the number of terms alto renther d=the common exit a1=the head start 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+cc 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 radio receiver 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 econo mys account that pays 5% annual recreate th! at is compound yearly. 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, secernate it on our website: OrderCustomPaper.com
