  • A45+9ij
  • B36+72ij
  • C81+81ij
  • D3672ij

Q3:

Determine ACB×(×) if Aij=5+5, Bij=4+3, and Cij=2+2.

  • A7070ij
  • B10+10ij
  • C60+80ij
  • D70+70ij

Q4:

Determine the volume of a parallelepiped on the vectors 𝑂𝐴, 𝑂𝐵, and 𝑂𝐶, given that the coordinates of points 𝑂, 𝐴, 𝐵, and 𝐶 are (3,5,3), (4,0,2), (2,4,0), and (0,5,3), respectively.

Q5:

True or False: (×)×=×(×)abccab.

  • AFalse
  • BTrue

Q6:

True or False: abcacbabc×(×)=()().

  • AFalse

True or False: The geometric meaning of the vector triple product abc×(×) is the volume of the parallelepiped defined by the three vectors a, b, and c.

  • ATrue
  • BFalse

Q8:

True or False: If (×)×(×)=abcd0, then the plane that contains a and b and the plane that contains c and d are parallel planes.

  • ATrue
  • BFalse
