We're looking for a scalar function
such that
. That is,


Integrate the first equation with respect to
:

Differentiate with respect to
:

Integrate with respect to
:

So
is indeed conservative with the scalar potential function

where
is an arbitrary constant.
Answer:
Top left
Step-by-step explanation:
In order for it to be a function, it has to pass the vertical line test. So draw a line down the middle of the graphs. If it passes once, then it is a function, if it passes more than once it is not.
Answer:
500
Step-by-step explanation:
Define listed price = C
Based on the term, to have the balance on both plan, the equation is 30+90%C = 80+80%C
- 30+0.9C=80+0.8C
- 0.1C=50
- 1C = 500
