Question

Using the distance formula whats the distance to the nearest tenth between A(-7,-4) and b(-2,0)

Answer 1

distance formula is \[\sqrt{(x-x)^2+(y-y)^2}\]
\[\sqrt{(-7+2)^2+(-4-0)^2}\]
\[\sqrt{(-5)^2+(-4)^2}\]
\[\sqrt{(25)+(16)}\]
\[\sqrt{31}\]

Answer 2

oops \[\sqrt{41}\]

Answer 3

Distance formula sucks

Answer 4

\[\sqrt{41}\approx6.4\]
