Assuming the series is

The series will converge if

We have

So the series will certainly converge if

, but we also need to check the endpoints of the interval.
If

, then the series is a scaled harmonic series, which we know diverges.
On the other hand, if

, by the alternating series test we can show that the series converges, since

and is strictly decreasing.
So, the interval of convergence for the series is

.
Answer:
C = 56.5 cm
Step-by-step explanation:
<h3>
The circumference formula is C = πd. If the diameter, d, is 18 cm, then the circumference of this circle is </h3><h3>
</h3><h3>
C = π(18 cm) ≈ 18π cm ≈ 56.5 cm</h3>
Answer:
Non-zero digits are always significant. Any zeros between two significant digits are significant. A final zero or trailing zeros in the decimal portion ONLY are significant.
Step-by-step explanation:
- Non-zero digits are always significant.
- Any zeros between two significant digits are significant.
- A final zero or trailing zeros in the decimal portion ONLY are significant.
