How do you do this question?

6/5

Divergent

Step-by-step explanation:

aₙ = (-6)ⁿ / (n 5ⁿ⁺²)

aₙ₊₁ = (-6)ⁿ⁺¹ / ((n+1) 5ⁿ⁺³)

lim(n→∞)│aₙ₊₁ / aₙ│

lim(n→∞)│[(-6)ⁿ⁺¹ / ((n+1) 5ⁿ⁺³)] / [(-6)ⁿ / (n 5ⁿ⁺²)]│

lim(n→∞)│[(-6)ⁿ⁺¹ / ((n+1) 5ⁿ⁺³)] × [(n 5ⁿ⁺²) / (-6)ⁿ]│

lim(n→∞)│[(-6)ⁿ⁺¹ / (-6)ⁿ] × [(n 5ⁿ⁺²) / ((n+1) 5ⁿ⁺³)]│

lim(n→∞)│-6 × n / (5 (n+1))│

lim(n→∞) (6n / (5n + 5))

6/5

The limit is greater than 1, so the series diverges.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

answer: i think one of the answer is $150 and $300?
