It's probably gonna be neither

For an odd function, f(-x)=-f(x)
for an even function, f(-x)=f(x)
to determine which, just try out a few numbers or look at a graph
I believe its neither

Magazines are packed into cartons for distribution. Each hour one person can pack 45 cartons. How many people are needed to pack

kipiarov [429]

Answer:

Step-by-step explanation:

One person can pack 45 cartoons per hour

Therefore the number of people needed to pack 1200 cartons can be calculated as follows

= 1200/45

= 26.66

= hence 26 people are needed to pack 1200 cartoons

Evaluate using integration by parts

Rather than carrying out IBP several times, let's establish a more general result. Let

$I(n)=\displaystyle\int x^ne^x\,\mathrm dx$

One round of IBP, setting

$u=x^n\implies\mathrm du=nx^{n-1}\,\mathrm dx$

$\mathrm dv=e^x\,\mathrm dx\implies v=e^x$

gives

$\displaystyle I(n)=x^ne^x-n\int x^{n-1}e^x\,\mathrm dx$

$I(n)=x^ne^x-nI(n-1)$

This is called a power-reduction formula. We could try solving for $I(n)$ explicitly, but no need. $n=5$ is small enough to just expand $I(5)$ as much as we need to.
