Question

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

Answer 1

68

Explanation:

Answer 2

The answer is 18.7 units

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) } \\ = √(324 + 25) \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ = √(349) \: \: \: \: \: \: \: \: \\ = 18.681541692... \: \: \: \: \:`

We have the final answer as

18.7 units to the one decimal place

Hope this helps you
