Question

What is the distance between the points (-4,-8) and (6,16), to the nearest tenth of a units?

A. 8.2 units
B.676.0 units
C.21.8 units
D.26.0 units

Answer 1

D.26.0 units

Explanation:

Given : the points A(-4,-8) and B(6,16),

Let d be the distance between A and B.

Then

`d=\sqrt{\left( 16-\left( -8\right) \right)^(2) +\left( 6-(-4)\right)^(2) }`

`=\sqrt{\left( 24\right)^(2) +\left( 10\right)^(2) }`

`=√(676 )`

`=26`
