Express the following vector in the form v= v, i + vaj + v3k. 3u - v if u = (6,5, -7) and v = (8, - 5,1) 3u - V= k (Simplify your answers.)Find a vector of magnitude 3 in the direction of v = 10i - 24k. The vector is k (Simplify your answer. Use integers or fractions for any numbers in the expression.)For the points P, ( - 2,2,3) and P2(3,3,0), find the direction of P, P2 and the midpoint of line segment P, P2. The direction of P, P2 is i+ Di+ ()K. (Type exact answers, using radicals as needed.)For the points P, (6,7,2) and P, (5,6,3), find the direction of P, P2 and the midpoint of line segment P, P2. The direction of P, P2 is K. (Type exact answers, using radicals as needed.)
