For x and y
When you subtract 2 from x, you will subtract 7 from y
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:
y = 2x
Step-by-step explanation:
Note the relationship between x and y, that is
x = - 42 → y = - 84 ← that is y = 2x
x = - 14 → y = - 28 ← that is y = 2x
x = 14 → y = 28 ← that is y = 2x
x = 42 → y = 84 ← that is y = 2x
Thus the linear equation is y = 2x
Ummmm I’m not sure but ya
We have been given an expression
. We are asked to choose the expressions, which are equivalent to our given expression.
Using exponent property
, we can rewrite our given expression as:

Upon looking at our given choices, we can see that option D is the correct choice.
Let us simplify our given expression.


Upon cancelling out
from numerator and denominator, we will get:

Using exponent property
, we will get:

Therefore, option B is a correct choice as well.
