Question 1
Vector a = (3, 4) and b = (1, 2). a + b = ?
- A) (4, 6)
- B) (2, 2)
- C) (3, 8)
- D) (4, 8)
Show answer
Answer: (4, 6)
Vector addition: add corresponding components. (3+1, 4+2) = (4, 6).

Question 2
Vector p = (5, -2). 2p = ?
- A) (10, -4)
- B) (7, 0)
- C) (5, -4)
- D) (10, -2)
Show answer
Answer: (10, -4)
Scalar multiplication: multiply each component by the scalar. 2 x (5, -2) = (10, -4).
-
Question 3
a = (4, 3). Magnitude |a|?
Show answer
Answer: 5
Magnitude (length) of vector (a, b) = sqrt(a^2 + b^2). sqrt(16+9) = sqrt(25) = 5.
