Respuesta:
E) 8
Explicación paso a paso:
Aplicamos la fórmula:
R: Radio vector; X= abscisa; Y = Ordenada
[tex]R^{2} = x^{2} + y^{2}[/tex]
[tex]r^{2} = (5\sqrt{2})^{2} + (\sqrt{14}) ^{2}[/tex]
[tex]r^{2} = 25.2 + 14 \\r^{2} = 50 + 14 \\r^{2} = 64\\r = 8 \\r = -8[/tex]
Pero recordemos que el radio vector siempre es positivo, entonces:
r = 8
