1. Determine the following: 3) Determine the vector equation of the plane that contains the following two lines Ll: r = (2, 3, 5) + t(3, 1, 5),teR L2: r = (2, 3, 5) + s(0,4,3),seR b) Determine the corresponding Cartesian equation. 2. A force, F = [12, 15, 47]N is applied over a distance of ti = [125, 85, 147]m. Determine the amount of work, measured in Joules, done in this situation. Given that these are math questions, I personally find solutions that are written on paper to be preferable. I need full steps for each question. I appreciate your great help.
