Final answer:
The vector u with magnitude 4 and direction 17 degrees is ⟨4cos(17°), 4sin(17°)⟩.
Step-by-step explanation:
The correct answer is A) ⟨4cos(17°), 4sin(17°)⟩.
To find the vector u with magnitude 4 and direction 17 degrees, we can use the formula:
u = ⟨4cos(θ), 4sin(θ)⟩
where θ represents the given direction angle.
Substituting θ = 17° into the formula, we get:
u = ⟨4cos(17°), 4sin(17°)⟩
Therefore, the correct answer is A) ⟨4cos(17°), 4sin(17°)⟩.
