9) The following rainfall amounts were recorded: June 2 1/2 inches, July 3 1/4 inches, August 4 1/5
castortr0y [4]

The average rainfall for the four months is 3 27/40 inches

<h3>How to find the average rainfall for the four months?</h3>

The rainfall amounts are given as:

June 2 1/2 inches, July 3 1/4 inches, August 4 1/5 and September 4 3/4 inches.

The average rainfall for the four months is calculated as:

Average = Sum of rainfall/Number of months

So, we have

Average = (2 1/2 + 3 1/4 + 4 1/5 + 4 3/4)/4

Evaluate the sum

Average = (14 7/10)/4

Evaluate the quotient

Average = 3 27/40

Hence, the average rainfall for the four months is 3 27/40 inches

How do I evaluate this integral?<img src="https://tex.z-dn.net/?f=%20%5Cint%5Climits%20%7B%20%5Cfrac%7Bx%7D%7Bx%5E4%2B1%7D%20%7D

One thing you could try is to set x=\sqrt y. This makes y=x^2, so that \mathrm dy=2x\,\mathrm dx, and y^2=x^4. So the integral is

\displaystyle\int\frac x{x^4+1}\,\mathrm dx=\frac12\int\frac{\mathrm dy}{y^2+1}=\frac12\arctan y+C=\frac12\arctan(x^2)+C

A "trickier" way to do it is to write

x^4+1=(x^2+\sqrt2x+1)(x^2-\sqrt2x+1)

so you could decompose the integrand into partial fractions. But that's more work than needed.
