Question

find the distance from P1 to P2. P1=(0,0,0) and P2=(4,1,2)

Answer 1

Answer:

The answer is $\sqrt{21}$

Step-by-step explanation:

Formula distance formula is $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_z)^2}$

Therefore distance between P$_1$(0,0,0) and P$_2$(4,1,2) is

                                    $=\sqrt{(4-0)^2+(1-0)^2+(2-0)^2}\\=\sqrt{4^2+1^2+2^2}=\sqrt{16+1+4}\\=\sqrt{21}$
