Find the distance between (-7, -2) and (11,3). Write your answer to one decimal.<br> Your answer

scoray [572]

Answer:

<h3>The answer is 18.7 units</h3>

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

(-7, -2) and (11,3).

The distance between them is

$d = \sqrt{( { - 7 - 11})^{2} + ({ - 2 - 3})^{2} } \\ = \sqrt{ ({ - 18})^{2} + ( { - 5})^{2} } \\ = \sqrt{324 + 25} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ = \sqrt{349} \: \: \: \: \: \: \: \: \\ = 18.681541692... \: \: \: \: \:$

We have the final answer as

<h3>18.7 units to the one decimal place</h3>

Hope this helps you
