The scalar product of u and v is zero, therefore...

• vectors u and v are parallel

• vectors u and v are perpendicular

• vectors u and v are equal

• vectors u and v are multiples

Find the magnitude of AB if the initial point is (-3, 1) and the terminal point is (3, 9).

• 6
• 8.2
• 10
• 10.4

What is the answer when you take dot product between two vectors?

• a vector

• a scalar

• a vector and scalar

• nothing

What do you need to get an equation of a line?

• A parallel vector

• A perpendicular vector

• A point on the line

• A parallel vector to the line and a point on the line

What do you need to get an equation of a plane?

• An orthogonal vector

• A normal vector to the plane

• A point on the plane

• An orthogonal vector to the plane and a point on the plane

What will we get when we take cross product between two vectors?

• A scalar

• A perpendicular vector

• A point on the plane

• A point on the line

When two planes intersect, then we will have

• 2 lines

• a line
