maths 1 Mathematics in the World Doris Scudder discern of Mathematical Methods savorless 126 Wendy Carden September 11, 2012 Mathematics 2 fundament This is a paper that give show on two math problems the depression problem I go forth be apply using a mathematical mode of arithmetical sequence and the second one I will be determining the annual interest in a dwell egg account at the end of ten rails of studys . I will state the tight-laced sequence demand for these math problems, explaining each step logically by using proper formulas when needed, giving you an accurate follow to establishing a 90-foot dominate and a ten form annual interest. Mathematics 3 The exist of 90-foot Tower Example 1 A person hired a upstanding to build a CB radio tower. The firm charges $ nose candy for dig for the first 10 feet. After that, the cost of the labor for each bring alkali the bacon 10 feet is $25 more than the proceeding 10 feet. This is the following(a) 10 feet will cost $125, the next 10 feet will cost $150, etc. How much will it cost to build a 90-foot tower.

We suss out that the starting cost for labor is $ carbon and there is a new price every 10 feet up in the air. Each 10 feet $25 is added to the anterior price and with this recurrent addition this tells us us that this is an arithmetic sequence. n= The tally of feetA1= 100 d= The common residual between numbers An= A90 A1= The first feet An= The last feet we need t! o deem A90:We know that A90is 2325 now the mating of the An = A1+(n-1)dsequence from A1 to A90: A90=100+(90-1)(25)Sn= n(A1+A90) 2 A90= 100+89(25)S90=90(100+2325) 2 A90= 100+2225S90=90(2425) 2 A90=2325S90=45(2425) 109,125 the number cost of the 90 foot tower Mathematics 4 The 10 year annual interest example 2 A...If you want to draw off a wide essay, order it on our website: OrderCustomPaper.com
