Answer:

A) -128x^8 - 384x^7

Step-by-step explanation:

The pattern is each term is multiplied by -2x which means by the eighth term youll have 8 x's in the first and 7 in the second. As you started off with a positive and multiplied it an even amount of time you'd end up with a negative answer. Think of it like this, it switches with each multiple so it would go: Positive, negative, positive, negative, this will get you a negative in the eighth term.

I know my explanation is a bit bad! I apologize!

Alecia deposited $500 in a savings account at 5% compounded semiannually. What is her balance after 6 years?
arlik [135]
Hello! The formula for compound interest is P ( 1 + r/n)^nt, where P = principal, r = percentage rate, n = times compounded per year, t = amount of time in years. This can be confusing, so let's take it step-by-step. 5% is the rate. 5% in decimal form is 0.05. Semi-annually means every 6 months. In other words, this is compounded 2 times a year. 0.05/2 is 0.025. 1 + 0.025 is 1.025. We're looking for the amount over 6 years. Now, we multiply n and t together. 2 * 6 = 12. The amount will be compounded 12 times over 6 years, so we raise the decimal to the 12th power. 1.025^12 is 1.34488882425, but don't delete that decimal from your calculator. Now, multiply that decimal by 500. When you do, you get 672.444412123 or 672.44 when rounded to the nearest hundredth. There. Alecia's balance after 6 years is $672.44.
