Seja a reta r dada por r: x = 1 + t, y = 2 e z = -1, t ∈ R. Assinale v ou f, justificando sua resposta. a) r é paralela ao eixo 0z.

b) O angulo entre r e s: (x + 5) / √2 = (y - 2) / 1 = z/ (-1) é de π / 4 rad.

c) Para que r seja ortogonal a p: (x, y, z) = (3, 1, -1) + h (m, 3, 7), h ∈ R, m deve ser igual a 1.
