Real World Applications

Week 1 Assignment Real World Applications plane 126 January XX, 20XX Real World Applications In lieu of not having a hold back on time to complete this assignment, I took the proactive approach to researching and solving the questions we readed to respond to. Upon my becomeings, because the question had recurrent additions, that tells us that in gild to solve the question, we must book an arithmetical sequence. There is a value in instinct how to comprehend and pay arithmetic sequence (otherwise known as arithmetic progression) in the real world, especially when hard to apply it to things such as Microsoft leap unwrap. Ive provided an example of doing it in Excel in the long fashion along with doing it by the equation. The Problem A person hired a degraded to fig a CB radio tower. The firm charges $ snow for restriction for the beginning(a) 10 feet. After that, the comprise of the labor for each deliver the goods 10 feet is $25 more than the preceding 10 feet. That is, the following(a) 10 feet give follow $125, the next 10 feet will cost $150, etc. How much will it cost to build a 90-foot tower? The Thought Process The upfront cost the firm charges for the prime(prenominal) 10 feet is $100. For each succeeding 10 feet, the cost is $25 more than the preceding 10 feet. The sum up number of measure (or terms as used in the example) is n=9 (90/10=9). The common cost digression is d=$25.

In this case, the first term, which means the first 10 feet be a1=$100. The last term is what we are trying to get. That is an=a9. Our goal is to find out what n equals here. By utilise t! he formula provided at bottom the text and found online when researching arithmetic sequence, we can find out the nth term of the sequence. an=a1+(n-1)d a9=100+(9-1)(25) a9=100+(8)(25) a9=100+200 a9=300 outright we need to figure out the sum of the sequence from a1 to a9. at a lower place is the work to get the solution. Sn=n(a1+a9) 2 Sn=9(100+300) 2 Sn=9(400) 2 Sn=$3600/2 Sn=$1800...If you want to get a full essay, govern it on our website: OrderCustomPaper.com
