Web-10i - 2j -10k. Vector AB = p.v.of B - p.v.of A. = (-10i - 2j -10k) - (-4i + pj - 6k). Vector AB = -6.i - (p+2).j -4.k. In right angled triangle OAB , vector OA and vector AB are perpendicular to each other, therefore :- (Vector OA) . (vector AB) = 0. or, ( -4.I +p.j -6.k). {-6.i - (p+2).j - 4.k} = 0. or, 24 - p. (p+2) + 24 = 0 . WebAnswer: a + (b -c) = -9i +10j Step-by-step explanation: You can use the distributive property to remove the parentheses: a + (b -c) = a + b - c Add the vectors as though they were binomials. a + b - c = (3 -2 -10)i + (4 +5 - (-1))j = -9i +10j Advertisement Advertisement
