Question

What is the distance between point P(–2, 1, 3) and point Q(–1, 4, –2) to the nearest tenth?

Answer 1

the different of P(a,b,c) and Q(d,e,f) is given by
\[\sqrt{(a-d)^2+(b-e)^2+(c-f)^2}\]

Answer 2

do you not understand?

Answer 3

not really

Answer 4

\[\sqrt{(-2-(-1))^2+(1-4)^2+(3-(-2))^2}=\sqrt{(-1^2)+(-3)^2+(5^2)}=\\\sqrt{1+9+25}=\sqrt{35} \approx 5.9\]

Answer 5

ask a question if you don't understand
