Answer:

  16.32 N11.38°E km/h

Step-by-step explanation:

16.0∠0° +3.22∠90° ⇒ (x, y) = (3.22, 16.0) ⇒ (r, θ) =

(3.22, 16.0) ⇒ (r, θ) = (√(3.22² +16²), arctan(3.22/16)*) = (16.32, 11.38°)

The woman's velocity is 16.32 km/h in a direction that is 11.38° east of north.

X^2 + 2x -4= 0

You need to remember one standard result

ax^2 + bx + c= 0

x =  \frac{ - b +  -  \sqrt{ {b}^{2}  - 4ac} }{2a}

By Comparing the coefficients,

a= 1, b=2, c=-4

x =  \frac{ - 2 +  -  \sqrt{ {2}^{2} - 4 \times 1 \times  - 4 } }{2 \times 1}  \\   x =  \frac{ - 2 +  -  \sqrt{4 + 16} }{2}  \\  \\  x =   \frac{ - 2  +  -  \sqrt{20} }{2}  \\  \\  x =   \frac{ - 2 +  - 2 \sqrt{5} }{2}  \\  \\ x =  - 1 +  -  \sqrt{5}
