Answer:
x = 23.5
Step-by-step explanation:
x is the midsegment theorem of the trapezoid given.
Based on the midsegment theorem of a trapezoid, thus:
x = (7 + 40)/2
x = 47/2
x = 23.5
Answer:
C
Step-by-step explanation:
A solution is where the line touches the x-axis, and the line touches 4 and 8, which means 4 and 8 are the two solutions.
Answer:

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.
