Answer:

$|5+13i|=\sqrt{194}$

Step-by-step explanation:

The given expression is $|5+13i|$ .

This is a complex number expression.

The absolute value of the complex number means the magnitude of the complex number.

Recall that;

$|a+bi|=\sqrt{a^2+b^2}$

This implies that:

$|5+13i|=\sqrt{5^2+13^2}$

$|5+13i|=\sqrt{25+169}$

$|5+13i|=\sqrt{194}$

Answer:

Option D: - 6; $\textbf{-5}\frac{\textbf{5}}{\textbf{2}}$ ; $\textbf{-4}\frac{\textbf{1}}{\textbf{5}}$ .

Step-by-step explanation:

The sequence is defined by:

$A(n) = -6 + (n - 1)\bigg( \frac{1}{5} \bigg )$

To find the first term of the sequence simply substitute n = 1.

First term of the sequence:

$A(1) = -6 + (1 - 1)\bigg( \frac{1}{5} \bigg )$

$= - 6$

Fourth term of the sequence:

$A(2) = -6 + (4 - 1) \bigg ( \frac{1}{5} \bigg)$

$= - 6 + 3\bigg( \frac{1}{5} \bigg)$

$= \frac{- 30 + 3}{5}$

$= \frac{-27}{5}$

$= \frac{-25 - 2}{5}$

$= - 5 - \frac{2}{5}$

$= -5\frac{2}{5}$ is the required answer.

Tenth term of the sequence:

$A(10) = - 6 + (10 - 1) \bigg( \frac{1}{5} \bigg)$

$= - 6 + 9\bigg( \frac{1}{5} \bigg)$

$= \frac{-30 + 9}{5}$

$= \frac{-21}{5}$

$= \frac{-20 - 1}{5}$

$= - 4 - \frac{1}{5}$

$= -4\frac{1}{5}$ is the required answer.
