Monica measures the number of bacteria that are living on her petri dish. Each day, she measures the amount of change in the number of bacteria. These amounts create a geometric sequence. Use the data in the table to determine the sum of the amounts of change in the bacteria after the seventh day. Day Amount of Change in Bacteria 1 12 2 โ36 3 108 4 โ324 6,564 2,184 60 โ2,184 Question 4(Multiple Choice Worth 3 points) (03.07 LC) Solve the summation from n equals 2 to 8 of negative 2 plus 5 times n. 92 146 161 164 Question 5(Multiple Choice Worth 3 points) (03.07 MC) Given the formula for an arithmetic sequence f(7) = f(6) + 4 written using a recursive formula, write the sequence using an arithmetic formula. f(7) = f(1) + 24 f(7) = f(1) + 20 f(7) = f(1) + 12 f(7) = f(1) + 4 Question 6(Multiple Choice Worth 3 points) (03.07 MC) Max is stacking logs at his campground for firewood. After his first load of logs, he has 9 logs on the stack. After his seventh load of logs, he has 51 logs on the stack. Use sequence notation to represent the arithmetic function. an = 51 + 6(n โ 1) an = 9 + 6(n โ 1) an = 51 + 7(n โ 1) an = 9 + 7(nโ 1) Question 7(Multiple Choice Worth 3 points) (03.07 LC) Represent the arithmetic series using the recursive formula. 94, 87, 80, 73, โฆ f(n) = f(1) + (7) f(n) = f(1) + (โ7) f(n) = f(n โ 1) + (7) f(n) = f(n โ 1) + (โ7) Question 8(Multiple Choice Worth 3 points) (03.07 LC) Represent the geometric series using the explicit formula. 2, โ8, 32, โ128, โฆ f(n) = 2 โ (โ4)(nโ1) f(n) = 2 โ (4)(nโ1) f(n) = f(n โ 1) โ (โ4) f(n) = f(n โ 1) โ (4) Question 9(Multiple Choice Worth 3 points) (03.07 LC) Find the sum of the first five terms of the geometric series 8, โ24, 72, โฆ 484 488 648 684 Question 10(Multiple Choice Worth 3 points) (03.07 MC) Monique deposited her money in the bank to collect interest. The first month, she had $225 in her account. After the sixth month, she had $273.75 in her account. Use sequence notation to represent the geometric function. an = 273.75 โ (1.04)nโ1 an = 273.75 โ (1.22)nโ1 an = 225 โ (0.22)nโ1 an = 225 โ (1.04)nโ1 You must check the box below prior to submitting your exam!
