Answer:

10 $\sqrt{2}$

Step-by-step explanation:

The given is a special right triangle with angle measures as follows:

45-45-90

The side lengths for this special right triangle are represented as follows:

a (the side length that sees angle measure 45)

a $\sqrt{2}$ (the side length that sees angle measure 90)

İn the image we can see that one of the side length that sees angle measure 45 is 10

so c, the side length that sees angle measure 90 (hypotenuse),

is equal to

10 $\sqrt{2}$

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.

All of the following expressions are equal except2^-31/8 2^1/2^48

madam [21]

Answer:

(D)8

Explanation:

$\begin{gathered} 2^{-3}=\frac{1}{2^3}=\frac{1}{8} \\ \frac{2^1}{2^4}=\frac{2}{16}=\frac{1}{8} \end{gathered}$

Therefore, every of the option is equal to 1/8 except 8.

The correct choice is D.
