We want to find such that . This means
Integrating both sides of the latter equation with respect to tells us
and differentiating with respect to gives
Integrating both sides with respect to gives
Then
and differentiating both sides with respect to gives
So the scalar potential function is
By the fundamental theorem of calculus, the work done by along any path depends only on the endpoints of that path. In particular, the work done over the line segment (call it ) in part (a) is
and does the same amount of work over both of the other paths.
In part (b), I don't know what is meant by "df/dt for F"...
In part (c), you're asked to find the work over the 2 parts (call them and ) of the given path. Using the fundamental theorem makes this trivial:
Answer with Step-by-step explanation:
Let A is non-singular
We have to prove that is unique.
Suppose B and C are inverse of A such that
and AC=I
By using property
Hence, the inverse of A is unique.
Addis Ababa is the capital of Ethiopa.
ANSWER
The correct answer is option B
EXPLANATION
The equations are
and
When we multiply the second equation by , we obtain;
When we combine this new equation with equation (1).
We can see that has been eliminated from the equation.
We can then, solve for and then substitute the result in to any of the equations to find .
Hence the correct answer is option B
Answer:
4(2 1/4x + y)
Step-by-step explanation:
Just factor
In this cae no GCF
So just divide By 4 becuase its easy
If you solve it
You’d get 9x+4y
WHich is the combined term of the expression given
