Convergent

Step-by-step explanation:

aₙ = n² 5ⁿ⁻¹ / (-6)ⁿ

aₙ = (-1)ⁿ n² 5ⁿ⁻¹ / 6ⁿ

aₙ = (-1)ⁿ n² 5ⁿ / (5 (6ⁿ))

aₙ = ⅕ (-1)ⁿ n² (5/6)ⁿ

bₙ = ⅕ n² (5/6)ⁿ

bₙ = ⅕ n² / (6/5)ⁿ

lim(n→∞) bₙ

lim(n→∞) [⅕ n² / (6/5)ⁿ]

Use L'Hopitals' rule:

lim(n→∞) [⅖ n / ((6/5)ⁿ ln(6/5))]

Use L'Hopitals' rule again:

lim(n→∞) [⅖ / ((6/5)ⁿ ln(6/5)²)]

0

The limit is 0, so the series converges.

point a is the center of this circle.

the ratio of the lengths of (ef/bc) and (ad/ih) is 2: 1.

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400
