Question

calcular a distância entre: (3, - 4) e (-4, 3)​

Answer 1

Oi

Vamos usar a fórmula e calcular ...

D = √(xb-xa)² + (yb-ya)²

D = √(-4-3)² + (3-(-4))²

D = √(-7)² + 7²

D = √49 + 49

D = √2.49

D = √2.7²

D = 7√2

Bons estudos ! :)

Answer 2

$\Delta x=-4-3=-7$

$\Delta y=3-(-4)=3+4=7$

$d=\sqrt{{(\Delta x)}^{2}+{(\Delta y)}^{2}}$

$d=\sqrt{{(-7)}^{2}+{7}^{2}}$

$d=\sqrt{49+49}$

$d=\sqrt{49.2}$

$\boxed{\boxed{d=7\sqrt{2}}}$
