Mat 126 Week 1 Assignment

difficulty #35 This date is arithmetic The cost to word form the crusade is $1800. STEPS/CALCULTATIONS YOU PERFORMED TO gain THE reply: The common difference in this time is $25, thus devising it an arithmetic sequence. The commandment for final examinationity the net marge is an = a1 + (n-1)d. In this problem, n=9 for the 9 sections of 10 foot sections, a1= light speed since that is the starting term of the sequence, and d=25 for the common difference. An = a1 + (n-1)d A9 = c + (9-1)25 A9 = 100 + (8)25 A9 = 100 + 200 A9 = 300 So the final term of the sequence is 300. Now that we know this, we de aime up find the coupling of the equipment casualty to calculate the final cost. The regulation for finding the trades union is Sn = n(a1 + an) 2 S9 = 9(100 + 300) 2 S9= 9(400) 2 S9= 3600 = 1800 2 So the final cost to build the 90-foot tower is $1800. Both of these formulas were put up on page 225 in Mathematics in Our World (Bluman, 2005). Problem #37 This sequence is geometric Ending remainder is $814.

45 STEPS/CALCULTATIONS YOU PERFORMED TO REACH THE event: To find the oddment offset, the formula of An = a1(rn-1) will be used. The sign balance is $500, the matter to is 5%, and the time continue is 10 years. 5% will be listed as 1.05 as the sign balance is 100% electropositive 5% interest, so one hundred five% is written 1.05. The number of terms is n=10, the scratch term is a1=525, the common ratio is r = 1.05. Although the initial balance is $500, a1 = $525 because the start-off term of the sequence is at the end of the first year, so it must include the interest on the $500. The final stage balance can now be found An = a1(rn-1) A10 = 525(1.05)9 A10 = 525(1.55132822) A10 = 814.447316 814.447316 can be travel to 814.45, thus showing that the ending balance after 10 years is $814.45. The formula to realize this problem was found on page 229 in in Mathematics in Our...If you desire to get a wax essay, order it on our website: Ordercustompaper.com
