Answer:

Step-by-step explanation:

Given expression is $|8-6 i|$ .

$|8-6 i|$ is a complex expression.

The value of i is –1.

By definition of absolute value, $|a+b i|=\sqrt{a^{2}+b^{2}}$

Now, substitute $|8-6 i|$ in the above formula.

$\Rightarrow|8-6 i|=\sqrt{8^{2}+(-6)^{2}}$ (since i = –1)

$=\sqrt{64+36}$ (since $8^{2}=64$ and $–6^{2}=36$ )

$=\sqrt{100}$ (Square root of 100 is 10)

= 10

Hence, the value of the expression $|8-6 i|$ is 10.

What is the slope 19,-16 -7,-15

zubka84 [21]

$\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ 19}}\quad ,&{{ -16}})\quad 
% (c,d)
&({{ -7}}\quad ,&{{ -15}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{-15-(-16)}{-7-19}\implies \cfrac{-15+16}{-7-19}
\\\\\\
\cfrac{1}{-26}\implies -\cfrac{1}{26}$

Consider the following data set:

Komok [63]

Answer:

+5 Range; The range is now 25

Step-by-step explanation:

The original range would be calculated by subtracting 20 from 40, giving you 20 as the range. However, with the point 15 added, there would be a new lowest number, making the new range be 40-15, which is 25.
