Introduction to Vector Review

Vector is a quantity with:

• magnitude and direction

• magnitude

• direction

• none of the above

Which symbol is used to show vector quantities?

• Circle
• Line
• Arrow
• Triangle

What is equal vectors?

• If two parallel vectors have the same values

• If they are in opposite directions

• If they have same magnitude and anti-parallel

Write in component form.

• <-8, -2>

• <8, 2>

• <2, 8>

• <-2, -8>

• (-1, 17)

• (1, -17)

• (-17, -1)

• (17, -1)

If y = <2, 0> and
z = <-1, -4>, find 3y - 2z.

• <5, -8>
• <4, 8>
• <8, 8>
• <-8, -8>

u + v

• 4i - j

• 6i + j

• 3j + 4j

• i + 6j

Find the magnitude of the vector -5i + 12j

• 13
• 10.91
• 7
• 17

Which of the following is the component form for a vector with initial point (-1, 5) and terminal point (6, 8)?

• <-3, -7>

• <3, -7>

• <-3, 7>

• <7, 3>
