Hi I need help with the following- I am stressed.

All i ask if you are able to help, is it possible you type each FINAL answer and then the explanation. Thank you so so much.

1)

Determine the sum of the first four terms of the geometric sequence where a = 1 and r = 2. The sum isLet a1, a2, a3,..., am... he a geometric sequence. Find S10 and 800. (Type an integer or decimal rounded to two decimal places as needed.) Find the sum of the innite geometric sequence (if it exists). (A) 5, 1o, 20, 4o, 80, 1 1 1 (B) 4, 1, 1' E, a, (A) What is the sum of the sequence 5, 10, 20, 40, 80, ...? Select the correct choice below and, if necessary, ll in the answer box within your choice. 0 A. The sum is Se,o = D. (Simplify your answer.) Q B. The sum does not exist. If a person borrows $7,200 and repays the loan by paying $300 per month to reduce the loan and 1% of the unpaid balance each month for the use of the money, what is the total cost of the loan over 24 months? The total cost of the loan is $D. (Type a whole number.) Let a1, a2, a3,..., am... be an arithmetic sequence. Find a24 and 834. (Simplify your answer.) The government, through a subsidy program, distributes $30,000,000. If each person or agency spends 80% of what is received, and 80% of this is spent, and so on, how much total increase in spending results from this goverment action? (Let a1 = 24,000,000.) The total increase in spending will be approximately $|:|. (Round to the nearest dollar as needed.) Cathy borrowed $6, 106.00 from her parents to finance a vacation. If simple interest was charged on the loan at 8.21% p.a., how much interest would she have to pay in 45 days? The interest charged would be $ (Round the final answer to the nearest cent as needed. Round all intermediate values to six decimal places as needed.)
