Question

Vectors u and v are perpendicular. ||u|| = 5√2 units, and ||v|| = 6√2 units. ||u + v|| ≈ ? units

A. 11.04
B. 11.05
C. 15.55
D. 15.56

Answer 1

Answer: 11.05

Step-by-step explanation: got it right

Answer 2

15.56

Explanation:

Given the vectors ||u|| = 5√2 units, and ||v|| = 6√2 units.

||u + v|| ≈ 5√2 + 6√2

||u + v|| ≈ (5+6)√2

Since √2≈ 1.4142

||u + v|| ≈ 11(1.4142)

||u + v|| ≈ 15.56

Hence the correct option is D
