Solving Problems in APA Style Format

Satisfactory Essays

This week assignment required to solve three problems derived from our text book in a mathematical essay APA style format. First am going to start by solving all three problems and later putting in words explaining the steps used in solving the problems including all mathematical and describe how and why this is applicable to my everyday life. The first part of the problem request to rewrite the expression (P dollars is invested at annual interest rate r for 1 year. If the interest is compounded Semiannually, then the polynomial P (1+r/2)2 represents the value of the investment after1 year. And to also Evaluate the polynomial resulting from step 1 using P = $200 and r = 10%, and P = $5670 and r = 3.5% 1. First let me start with the first part of the question, which is rewriting the expression without parentheses. I am using the FOIL method by multiply the pairs: front, outside, inside, etc. P(1+r/2) ^2 The original expression P(1+r/2)*(1+r/2) A squared quantity multiplies itself P(1+r/2+r/2+r^2/2 The expression after FOIL was carried out P(1+r+r^2/4) Like terms are combined with r/2 + r/2 = r P+Pr+Pr^2/4 The P is distributed across the trinomial Usually traditional polynomials are in descending order of the variable r, but I notice that this one is in ascending order with the highest exponent in the last term instead of the first term. Now I can evaluate the first expression by plugging in P = $200 and r 10% = 0.1 interest rate as in decimal P+Pr+Pr2/4 the
