. The series is divergent. To see this, first observe that the series ∑ 1/kn for n = 1 to ∞ is divergent for any integer k ≥ 2.
Now, if we pick a large integer for k, say k > 100, then for nearly all integers n it will be true that 1 > cos(n) > 1/k. Therefore, since ∑ 1/kn is divergent, ∑ cos(n)/n must also be divergent The *summation* is divergent, but the individual terms converge to the number 0.<span>by comparison test since cosn/n <= 1/n is convergent
and 1/n is divergent by harmonic series
so the series is conditionally converget </span>

Answer:
1. The sum of interior angles of a pentagon is 180 but here the sum of angles of this pentagon is 550 . So it is wrong.
2. Angle 145 is equal to the corresponding of angle y. So angle y is 145 degree.So according to opposite angle theorem, angle x is also 145 degree.
Sorry I do not know next question solutions.
Answer:
$15.56
Step-by-step explanation:
So start by doing a 10% tip, because you just move the decimal place over by 1, so $1.35, and then divide that by 2 to get 5% which is .68, and add them to get 2.03. You can get the same answer by multiplying 0.15 to 13.53. 13.53 + 2.03 is 15.56. Hope this helped and have an awesome day!
