Question

What is the distance between the points (-4, 8) and (10,-8)?

Answer 1

You have to use distance formula.

(-4,8) and (10,-8)

$\sqrt{(10 - (-4))^{2} + ((-8) - 8)^{2} }$

just for sake of making it easier to explain, let's use this:

[ (10 + 4)^2 + (-8 - 8)^2 ]^(1/2)

------------------------------------------------------------------------------

[ (10 + 4)^2 + (-8 - 8)^2 ]^(1/2)

= [ (14)^2 + (-16)^2 ]^(1/2)

= [196 + 256]^(1/2)

= (452)^(1/2) = $\sqrt{452}$

= 21.2029...

rounding up to 21 units between those points

Answer 2

Answer:

14 apart from each other.
