Definition:

A <em>decimal point</em> is the symbol that is used to make the separation between the whole part and the fractional part of a number. Currently, not only is a point used to separate both parts, but the comma can also be used.

Example:

The number 39.847, in which 39 is the whole number, while 847 is the decimal part where 8 represent tenths, 4 hundredsths, and 7 thousandths.

Find the exact distance between (5, 3) and (-2, 8).

Brrunno [24]

Answer:

The answer is

<h2> $\sqrt{74} \: \: \: \: units \\$ </h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(5, 3) and (-2, 8)

The distance between them is

$d = \sqrt{( {5 + 2})^{2} + ( {3 - 8})^{2} } \\ = \sqrt{ {7}^{2} + ({ - 5})^{2} } \\ = \sqrt{49 + 25} \\ = \sqrt{74} \: \: \: \: \: \: \: \: \: \:$

We have the final answer as

$\sqrt{74} \: \: \: \: units \\$

Hope this helps you

Nastasia [14]

Answer:

Step-by-step explanation:

$\frac{1}{x}=\frac{1}{1-\sqrt{2}}\\\\=\frac{1*(1+\sqrt{2})}{(1-\sqrt{2})(1+\sqrt{2})}\\\\=\frac{1+\sqrt{2}}{1^{2}-(\sqrt{2})}\\\\=\frac{1+\sqrt{2}}{1-2}\\\\=\frac{1+\sqrt{2}}{-1}\\\\= -[1+\sqrt{2}]\\\\x-\frac{1}{x}=1-\sqrt{2}-(-[1+\sqrt{2}])\\\\=1-\sqrt{2}+1+\sqrt{2}\\\\=2$
