Answer:
Convergent
Step-by-step explanation:
This is an alternating series where bn = 2n / eⁿ. Apply the alternating series test:
lim(n→∞) bn
= lim(n→∞) (2n / eⁿ)
Use L'hopital's rule:
= lim(n→∞) (2 / eⁿ)
= 0
For n ≥ 1, the series is decreasing. 2(n+1) / eⁿ⁺¹ < 2n / eⁿ.
Therefore, the series converges.
Answer:
$72
Step-by-step explanation:
Divide the current bill by what it increased by to find the bill from last year.
79.20/1.10 = 72
2000 pounds in a ton + 200 pounds = 2200 pounds. (for C)
16 ounces in a pound, so (for E)
(2100)+(1600/16) = 2200 pounds
