Question

Determine a distância entre os pontos

W (3, 4) e K (7, 4).



Alguém me ajuda por favor!!!

Answer 1

$\mathsf{(x_{w}-x_{k})^2=(3-7)^2=(-4)^2=16}$

$\mathsf{(y_{w}-y_{k})^2=(4-4)^2=0^2=0}$

$\mathsf{d_{w,k}=\sqrt{(x_{w}-x_{k})^2+(y_{w}-y_{k})^2}}$

$\mathsf{d_{w,k}=\sqrt{16+0}=\sqrt{16}}$

$\huge\boxed{\boxed{\boxed{\boxed{\mathsf{d_{w, k}=4}}}}}$
