First we have to assume that each quarter touched each other. Hence the area of the table not covered by the coins (A) is equal to the total area of the table (At) minus the total area of the coins (Ac). Coins are circle, so 
and r =24.26mm. The area of one coin is then 1848.98mm^2. Hence the equation is A = At - xAc where x is the number of coins.
The complete question is:
A geometric sequence is defined recursively by
(a) Write out the first four terms of this sequence.
(b) Is the 9th term of this sequence larger or smaller than 1/10? Show the calculation that you use to determine your answer.
Answer:
- <u>The 9th term is larger than 1/10.</u>
Explanation:
You are given the first term, , and the recursive formula
Thus, you can find the sequence of terms by multiplying each term by the constant ratio, (-1/2).
<u>(a) First four terms of the sequence</u>
Those are the first four terms.
<u>(b) 9th term</u>
You can write the explicit formula of the sequence as:
Thus, for the 9th term, n = 9, and the term is:
Since 1/10 = 0.1, and 0.1 < 0.1526, the 9th term is larger than 1/10.
