Answer:
1. n + 8 = 10
2. = 10
3. 8n - 6 = 34
4. 3(n + 12) = 45
5. No
6. Yes
Step-by-step explanation:
(only for questions 5 and 6)
5. If you substitute in y = 1, you get 1 * 49 = 0 or 49 = 0 which is not true.
6. If you substitute in b = 8, you get:
this is true.
B and C are absurd; if a series converges, it must have a sum, but if a series diverges, it cannot have a sum.
Now, notice that
That is, we can write the sum more compactly as
The series is geometric with common ratio
, so the series converges (and thereby has a sum), so the answer is D.
