Question

What is the distance between (5, 6, 4) and (4, 4, 2)? Round to the nearest tenth of a unit

Answer 1

basically the same as the 2d distance formula http://www.calculatorsoup.com/images/equations/distance-three-coordinates.png

Answer 2

wat

Answer 3

did you never have to find the distance between, say (2,1) and (5,6)?

Answer 4

let's make \((x_2,y_2,z_2)= (5, 6, 4) \\(x_1,y_1,z_1)= (4, 4, 2) \)
plug and chug

Answer 5

so you change the x^2, y^2, z^2 for (4,4,2)

Answer 6

hold up time for more color coding

Answer 7

pls dont bib ily

Answer 8

but yeah, just put the green shape into the green hole
just like kindergarten
ily2

Answer 9

ok I'll write it out

Answer 10

I'll start you off.
\(\sqrt{(5-4)^2+(y_2-y_1)^2+(z_2-z_1)^2}\)

Answer 11

wait im confused now

Answer 12

had to switch to a new browser

Answer 13

sorry bibby :c

Answer 14

why apologize lol

Answer 15

Answer 24

hahahaha

Answer 25

why do you do this to me

Answer 26

ILY

Answer 27

\((\color{green}{x_2},\color{cyan}{y_2},\color{red}{z_2})= (\color{green}5, \color{cyan}{-6}, \color{red}{4}) \\(\color{purple}{x_1},\color{blue}{y_1},\color{pink}{z_2})= (\color{purple}4,\color{blue}{-4}, \color{pink}{-2})\\
\large d=\sqrt{(\color{green}{x_2}-\color{purple}{x_1})^2+(\color{cyan}{y_2}-\color{blue}{y_1})^2+(\color{red}{z_2}-\color{pink}{z_2})^2}\)
same method, different numbers
