Given:
The sequence is 2, 4, 8, 16,... .
To find:
The explicit formula for the sequence and use it to find the eleventh teen in the sequence.
Solution:
We have,
2, 4, 8, 16,...
It is a GP because the ratio between two consecutive terms are same..
Here,
First term:
Common ratio:
The explicit formula of GP is:
Putting , we get
Put n=11 to find the 11th term of the given sequence.
Therefore, the correct option is D.
Answer:
19.8 or 19 4/5
Step-by-step explanation:
Step 1: Set up the expression.
Step 2: Simplify.
Therefore, the answer is 19.8 or 19 4/5.
A)
well, you started with 38 miles and are going 62mph, so every passing hour you're 62 miles farther, so say after "h" hours, you have gone
38 + 62h miles eastward.
your friend is going southward starting with 20 and going 65mph, so after "h" hours she's gone
20 + 65h miles then.
now in 2 hours, that's h = 2, so you've gone
38 + 62(2) and she's gone
20 + 65(2), so check which is larger.
b)
well, when your and her are the same distance from Seattle, is when the miles covered by both are
equal, when is that? well
