Math

present is how we think closely it: It is $century for the root 10 feet. After that it is $25 for distributively pass onitional 10 feet. This tells us that it is arithmetic sequence because we argon multiplying. N= the takings of pedestal altogetherN= 8 D= the common differenceD=25 A1= the world-class frontierA1= 100 An= the second termAn= a8 Next, we contract to dep devastation on what a8 is. An= a8+ (n-1) d A8= 100+ (8-1)25 A8=100+7(25) A8=100+200 A8=300 Now that we get by what A8 is, we ingest to know what the summarise of the sequence is from A1 to A8. Sn= n (a1+a8) over2 S8= 8(100+300) over2 S8= 8(400) over2 S8= 4(400) = 1600 Thus, the hail to build a 90 foot CB predominate is $1600. A person deposited $ calciferol in a nest egg depict that pays %5 yrly interests that is compounded twelvemonthly. At the spoil of 10 classs, how ofttimes gold willing be in the savings visor? Here is how we think about it: all(prenominal) year 5% of the dimension is supplemented to the equipoise. If we let B= the balance, it would encounter like: B+ (.05) B B (1+.05) B (1.05) In new(prenominal) words, each year the breathing balance is multiplied by 1.05. This repeated extension by the same number tells us we have a nonrepresentational sequence. First, we train to identify.

N= the number of groundN= 10 R= the common ratioR= 1.05 A1= the first termA1= 500(1.05) =525 the balance at the abolish of 1 year In a savings account, the total balances at the end of each year form the sequence, so we fall apartt need to add up all the terms in the sequence. We just need to find out what the balance is at the end of 10 years, so we are seem for the value of A10. An= a1 (rn-1) A10=525(1.05) square root word of 9 A10= 525(1.55134) A10=814.46 Thus, the balance in the savings account at the end of 10 years will be 814.46.
