Question

calcula la distancia entre los puntos A(-5,-4) y B (0,2)​

Answer 1

Respuesta:

Explicación paso a paso:

$A (x_{1} ,y_{1})$

$B (x_{2} ,y_{2})$

$d = \sqrt{(y_{2} -y_{1} )^{2}+(x_{2} -x_{1} )^{2} }$

$A ( -5, -4)$

$B(0,2)$

$d = \sqrt{[2 -(-4) ]^{2}+[0-(5)]^{2} }$

$d = \sqrt{(2 + 4) ^{2}+(-5)^{2} }$

$d = \sqrt{(6) ^{2}+(-5)^{2} }$

$d = \sqrt{36+25 }$

$d = \sqrt{61}\approx7.81$
