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.
_____
This is her velocity in any stationary frame of reference.
____
* We have used North as the reference for the angle, measured CW.

Answer:
The function given is non-linear.
Step-by-step explanation:
The slope between (0, 2) and (2,6):

The slope between (2,6), and (3, 12):

Since the slopes are not equal to each other, the function is non-linear. A linear function's slope must stay consistent.
Hope this helps.
Answer: The answer here is x=12.49
Step-by-step explanation:
The idea is tho remove the brackets on the right hand side by multiplying by 4.9
4.90= 10(x-12)
4.90=10x-120
x=12.49
total = 19.99 + 0.10(x-300) + 0.25y
x = 375
y=54
total = 19.99 +0.10(375-300) +0.25(54)
total = 19.99 + 0.10(75) + 0.25(54)
total = 19.99 + 7.50 + 13.50
total = $40.99
