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:
Your choice is correct.
Step-by-step explanation:
magnitude = √(6² +5²) = √61 ≈ 7.81
direction = arctan(5/6) ≈ 39.81°
The polar coordinates are (7.81, 39.81°).
Answer:
-4x - 3.
Step-by-step explanation:
f(x) = -4x + 5.
f(x + 2) = -4(x + 2) + 5
= -4x - 8 + 5
= -4x - 3.
Hope this helps!
Given:
7 acres planted with peas and carrots.
peas represented by p. carrots represented by c.
p + c = 7
2,000 per acre of peas
1,000 per acre of carrots
goal income: 7,000
2000p + 1000c = 7000
The constraint in his system of equation would be: p + c = 7
Answer:
x = 5
Step-by-step explanation:
NOTE: THE 2 SIDES ARE THE SAME LENGTH
THEY HAVE TO BE SMALLER THEN 10
So 10/2 = 5
x = 5
