Its pretty simple, its x then y, if u have any questions message me
. 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>
(a) y = -7/5x + 17.8
(b) it decreased by 7/5 per day.
Hope this helps!!! :)
Answer:
Expose both of left side and right side.
For example: on the left side: 2(x+6) = 2x + 6.
