A certain granola bar has 2 grams of fiber. This is 8% of the recommended daily value. How many grams of fiber are recommended d

xeze [42]

If you formulate the question into a word equation it comes out:

2 grams fiber = .08 × DRV
↑ ↑ ↑ ↑ ↑
2 g fiber is 8% of the daily recommended value.

Now solve for DRV to find the daily recommended value:

2 g fiber/.08 = DRV

DRV = 25 g fiber

Answer the question with explanation;

Answer:

The statement in the question is wrong. The series actually diverges.

Step-by-step explanation:

We compute

$\lim_{n\to\infty}\frac{n^2}{(n+1)^2}=\lim_{n\to\infty}\left(\frac{n^2}{n^2+2n+1}\cdot\frac{1/n^2}{1/n^2}\right)=\lim_{n\to\infty}\frac1{1+2/n+1/n^2}=\frac1{1+0+0}=1\ne0$

Therefore, by the series divergence test, the series $\sum_{n=1}^\infty\frac{n^2}{(n+1)^2}$ diverges.

EDIT: To VectorFundament120, if $(x_n)_{n\in\mathbb N}$ is a sequence, both $\lim x_n$ and $\lim_{n\to\infty}x_n$ are common notation for its limit. The former is not wrong but I have switched to the latter if that helps.
