Question

Find the distance between the points (-4, 6) and (8, -12).Round your solution to 2 decimal points.

Answer 1

you can get a ruler to measure it

Answer 2

i dont have a ruler

Answer 3

\(\large \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
&(-4\quad ,&6)\quad &(8\quad ,&-12)
\end{array}\qquad
d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}
\)

Answer 4

It only cost like $1.99 at walmart

Answer 5

I am aware of how much one is.

Answer 6

$1.99 for a ruler? I can find it cheaper than that
for $1.99 they must make some profit I'd think, I mean, they paid about 25cents

Answer 7

d = sq rt (x2 - x1)^2 + (y2 - y1)^2
d = sq rt (8 - (-4)^2 + (-12 - 6)^2
d = sq rt (8 + 4)^2 + (-18^2)
d = sq rt 144 + 324
d = sq rt 468
d = 21.633 rounds to 21.63
