Name: 1. Find the volume for the parallelepiped(BOX) formed by the vectors: 3 = (1,4,7),B = (2,1,4),and2 = (o,-9,18) 3 (raga-1),; = (5,4,2) 2. Find the angle between the vectors: 3. f = (13:2) Find parametric equations and symmetric equations of the line that passes through the point (5,1,3) and is parallel to the vector 4. x2y+3z =1x+y+z '1 Find the angle between the planes 5. Find the equation of the plane that passes through the points P=(1,3,2), Q=(3,-1,6), and R=(5,2,0) 6. Reduce the equation to standard form, classify the surface, and sketch it. 43::2 +12"a +4zz4y24z+36=0
