For this case we can write the vector in the following way:
 v = 23 (cos (270) i + sin (270) j)
 Rewriting we have:
 v = 23 (0i - 1j)
 v = -23j
 Answer:
 The vector written as a linear combination is given by:
 v = -23j

The answer for Honors Pre-calculus Connections Academy unit 5 lesson 4 Direction Angle is:

1.  B 110.6 degrees
2. C u=(3.5,2)
3. D v=-23j
4. A 25 knots at 166.5 degrees.
100%
