Step-by-step explanation:
Given:
This field will have a scalar potential if it satisfies the condition . While the first x- and y- components of are satisfied, the z-component doesn't.
Therefore the field is nonconservative so it has no scalar potential. We can still calculate the work done by defining the position vector as
and its differential is
The work done then is given by
2x+3(x-2)-3(x-6)
You would first distribute.
So:
2x+3x-6-3x+18
Then you would combine like terms, like so:
2x+3x-3x= 2x
-6+18= 12
So it'd be:
2x + 12
Which is answer choice A

Answer:
The correct option is;
Two-tailed test
Step-by-step explanation:
From the interpretation of the question statement, the trader wants to conduct a hypothesis test on the trader's claim that the proportion of stocks that offer dividends is different from 0.14
Given that the difference is hypothesized, then the null hypothesis, H₀ and the alternative hypothesis, H₁ should be written as follows;
H₀: Null hypothesis (no difference, or no change)
H₁: μ ≠ μ₀ which is hypothesizing difference which is known as a two-tailed test
The confidence level is then selected and the test statistic is calculated
G(x) - f(x) = -2x -5
Since f(x) and g(x) has the same domain of R, so the domain should still be R(if you don't consider complex numbers)
