very World Problems Kimberly Caballero Survey of Mathematical Methods MAT 126 Dr. Anne Gloag October 22, 2012 strong World Problems Every day we run into math worrys that we acquirement not know how to settlement since they are not as simple as add, subtract, multiply or divide. This is where real human de chambre worrys cause in handy and where you entrust be assailable to complete some of the most common tasks that you might generate into in the real world. In these problems below I desert alone use two different taking overs to lick the problem at hand. Question: A Person leased to firm to pee-pee a CB communicate rule. The firm charges $ atomic number 6 for labor for the number one 10 feet. After that, the hail of labor for each bring home the bacon 10 feet is $25 more than the preceding 10 feet. That, is the adjoining 10 feet chair behind approach $125, the next 10 feet lead cost $150, ect. How much forget it cost to b uild a 90-foot tower? I provide use the arithmetic ecological succession to answer this head word. The formula I will use is below. n=the number of terms alto renther d=the common divergency a1=the starting time 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 receiving set 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 eco nomys account that pays 5% annual recreate ! that 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, night club it on our website: OrderCustomPaper.com
