Use the ratio test to show that the series is convergent.<br><br> Thank you!

igor_vitrenko [27]

Step-by-step explanation:

lim(n→∞) |aₙ₊₁ / aₙ|

lim(n→∞) | (4ⁿ⁺¹ / (n+1)!) / (4ⁿ / n!) |

lim(n→∞) | (4ⁿ⁺¹ / (n+1)!) × (n! / 4ⁿ) |

lim(n→∞) | 4 / (n+1) |

Since the limit is less than 1, the series converges.

Keats Library purchases a number of new books, all in the category of biography; the library does not acquire any other books. W

PtichkaEL [24]

Answer:

$\large \boxed{87.5 \, \%}$

Step-by-step explanation:

Let x = the original number of books

Then 0.375x = the total number of biographies

and 0.20 x = the original number of biographies

$\text{Percent increase} = \dfrac{\text{ New number - Old number }}{\text{Old number }} \times 100\, \%\\\\= \dfrac{0.375x - 0.20x}{0.20x} \times 100\, \% = \dfrac{0.175x}{0.20x} \times 100\, \% = 0.875 \times 100\, \% = \mathbf{87.5 \, \%}\\\\\text{The number of biographies has increased by $\large \boxed{\mathbf{87.5 \, \%}}$}$
