Does this sum converge: show steps

ehidna [41]

Answer:

Yes

Step-by-step explanation:

$\sum_{n=1}^{\infty} e^{-\sqrt{n} } \\\sum_{n=1}^{\infty} (\frac{1}{e})^{\sqrt{n} }$

If we say u = √n, then:

$\sum_{u=1}^{\infty} (\frac{1}{e})^{u}$

This is a geometric series. Since |1/e| < 1, the series converges.

Let x represent the answer.
7 + x = (43+x) / 3
3(7+x) = 43+x
21+3x = 43+x
2x = 22
x = 11

The answer is 11

Round 8.54 to nearest tenth

Molodets [167]

If you look at the image below, you can find what the tenths place is.
Juts follow the rule: 5 or more raise the score, 4 or less stay and res(t)
Therefore 8.54 would raise to 8.5 Since the four is lower than five, it rounds down.
~Hope this helped :)
