Question

21. Find the distance between the points. Leave your answer

as a simplified square root
(-8,5), (-1.1)?

PLEASE answer as fast as you can. thanks​

Answer 1

The answer is

`√(65) \: \: \: units`

Explanation:

To find the distance between two points we use the formula

`\sqrt{ ({x1 - x2})^(2) + ( {y1 - y2})^(2) }`

where

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

From the question the points were

(-8,5), (-1.1)

Substitute the values into the above formula

That's

`\sqrt{ ({ - 8 + 1})^(2) + ({5 - 1})^(2) }`

`\sqrt{ ({ - 7})^(2) + {4}^(2) }`

`√(49 + 16)`

We have the final answer as

`√(65) \: \: units`

Hope this helps you
