Units of Capacity
marysya [2.9K]

Answer:

            \large\boxed{\large\boxed{0.2deciliter}}

Explanation:

Build your conversion factors using the conversion table:

  • 1 cup = 0.237 liters\implies 1=0.237liters/1cup

From the prefixes used in the metric system, you know that 1 deciliter = 0.100 liters. Then:

  • 1 deciliter = 0.100 liters\implies 1=1deciliter/0.100liters

Arrange the expression to simplify the units and convert from cups to deciliters:

  • 9cups\times 0.237liters/cup\times 1deciliter/0.100liters=0.2133deciliter

Round to the nearest tenth: 0.2 deciliter.

Determine whether the following series converge or diverge
Mars2501 [29]
An alternating series \sum\limits_n(-1)^na_n converges if |(-1)^na_n|=|a_n| is monotonic and a_n\to0 as n\to\infty. Here a_n=\dfrac1{\ln(n+1)}.

Let f(x)=\ln(x+1). Then f'(x)=\dfrac1{x+1}, which is positive for all x>-1, so \ln(x+1) is monotonically increasing for x>-1. This would mean \dfrac1{\ln(x+1)} must be a monotonically decreasing sequence over the same interval, and so must a_n.

Because a_n is monotonically increasing, but will still always be positive, it follows that a_n\to0 as n\to\infty.

So, \sum\limits_n(-1)^na_n converges.
