24. Write a vector (-3, 22, -3) as a linear combination of the vectors (-1, 2, 3) and (0, 4, -3). 25. A plane is steering at S83°E at an air speed of 550km/h. The wind is from N70°E at 85km/h. Find the ground velocity of the plane to 1 decimal and include a proper diagram. 26. Given the points of a triangle; A (3, 5, -1), B (7, 4, 2) and C (-3, -4, -7). Determine the area of the triangle.
