The answer is:  "about 2" .
___________________________________________

13% of 15 is _?_<span>_ ?
</span>
13% = 13/100 = 0.13 
 
15 * 0.13 = 1.95 ;   so about 2 animals (devils, in this case).

If pie-0 =3.14159265359 what is pie time 160=
Zepler [3.9K]

Answer:

Hey!

To start this problem, we'll most likely need a calculator. Handling \pi can get a little messy, and tricky.

(also note that "pie" is a food, the mathematical term \pi, is pronounced "pie", but spelled "pi.")

Anyway, multiplying 3.14159265359..... (\pi) \cdot 160 = 502.654824574...... going on and on.

In general, these types of problems are better for a calculator if you want an exact answer. Otherwise, just resort to estimation. \pi is pretty close to 3.14.

160 \cdot 3.14 = 502.4, which is decently close to our other answer.

Hope this helps!

What are all values of x for which the series shown converges? ​
adoni [48]

Answer:

One convergence criteria that is useful here is that, if aₙ is the n-th term of this sequence, then we must have:

Iaₙ₊₁I < IaₙI

This means that the absolute value of the terms must decrease as n increases.

Then we must have:

\frac{(x -2)^n}{n*3^n} > \frac{(x -2 )^{n+1}}{(n + 1)*3^{n+1}}

We can write this as:

\frac{(x -2)^n}{n*3^n} > \frac{(x -2 )^{n+1}}{(n + 1)*3^{n+1}} = \frac{(x -2)^n}{(n + 1)*3^n} * \frac{(x - 2)}{3}

If we assume that n is a really big number, then:

n + 1 ≈ 1

And we can write:

\frac{(x -2)^n}{n*3^n} > \frac{(x -2)^n}{(n)*3^n} * \frac{(x - 2)}{3}

Then we have the inequality

1 > (x - 2)/3

And remember that this must be in absolute value, then we will have that:

-1 < (x - 2)/3 < 1

-3 < x - 2 < 3

-3 + 2 < x < 3 + 2

-1 < x < 5

The first option looks like this, but it uses the symbols ≤≥, so it is not the same as this, then the correct option will be the second.
