Please help IM SO CONFUSED!

Mathematics
1 answer:
rodikova [14]3 years ago
4 0

Answer:

18

Step-by-step explanation:

You can see from the table that 2 bracelets are made every 30 minutes.

There are 9 intervals of 30 minutes each in 4.5 hours.

So, the number of bracelets that are made in 4.5 hours is

9x2=18

Another way to see this is to note from the table that 4 bracelets are made in 60 minute, which is 1 hour.  So, in 4 hours, 16 bracelets will be made. Also, from the table, 2 bracelets are made in 30 minutes, which is 1/2 hour.  So, adding up, 18 bracelets are made in 4.5 hours.

Not sure how to approach this one, any help would be appreciated!

The continuity of f' and its limiting behavior guarantees that f' is Riemann integrable, so you can write

\displaystyle\int_0^\infty f'(x)\,\mathrm dx=uv\bigg|_{x=0}^{x\to\infty}-\int_0^\infty v\,\mathrm du

where u=1\implies\mathrm du=0\,\mathrm dx and \mathrm dv=f'(x)\,\mathrm dx\implies v=f(x), so that

\displaystyle\int_0^\infty f'(x)\,\mathrm dx=f(x)\bigg|_{x=0}^{x\to\infty}=\lim_{x\to\infty}f(x)-f(0)=-f(0)
