Find the volume of the parallelepiped with one vertex at (5,-1,-5), and adjacent vertices at (11,-7,-9), (12,3,-4), and (2,5,-11). Volume= [11- 2 (1 point) Let I. be the line in R³ that consists of all scalar multiples of the vector proj₁ x = Find the orthogonal projection of the vector x = 4 onto L. 8
