Solution. Determine the common ratio, Since the common ratio r = 1 3 is a fraction between − 1 and 1, this is a convergent geometric series. Use the first term a1 = 3 2 and the common ratio to calculate its sum. S∞ = a1 1 − r = 3 2 1 − (1 3) = 3 3 2 3 = 3 2 ⋅ 3 2 = 9 4. Answer: S∞ = 9 4. Start today. $9.95 per month (cancel anytime).

Study with Quizlet and memorize flashcards containing terms like Functions of the skin include Select one: a. synthesizing antibodies. b. regulating body temperature. Correct c. synthesizing digestive enzymes. d. release of large amounts of hormones. e. producing adipose tissue., As cells are pushed from the deeper portion of the epidermis toward the surface, Select one: a. they divide. b But there is a faster way once you see the pattern. Make your chart for up to i^4. Then find the multiple of 4 closest, but less than the power. In this case 16 is the largest multiple of 4 less than 18. So i^16 = i^4 = 1. The count two more in the sequence. i^17 would be like i^1 = i. i^18 would be like i^2, or -1. .
