For each of the following vector fields

olga nikolaevna [1]

(A)

$\dfrac{\partial f}{\partial x}=-16x+2y$

$\implies f(x,y)=-8x^2+2xy+g(y)$

$\implies\dfrac{\partial f}{\partial y}=2x+\dfrac{\mathrm dg}{\mathrm dy}=2x+10y$

$\implies\dfrac{\mathrm dg}{\mathrm dy}=10y$

$\implies g(y)=5y^2+C$

$\implies f(x,y)=\boxed{-8x^2+2xy+5y^2+C}$

(B)

$\dfrac{\partial f}{\partial x}=-8y$

$\implies f(x,y)=-8xy+g(y)$

$\implies\dfrac{\partial f}{\partial y}=-8x+\dfrac{\mathrm dg}{\mathrm dy}=-7x$

$\implies \dfrac{\mathrm dg}{\mathrm dy}=x$

But we assume $g(y)$ is a function of $y$ alone, so there is not potential function here.

(C)

$\dfrac{\partial f}{\partial x}=-8\sin y$

$\implies f(x,y)=-8x\sin y+g(x,y)$

$\implies\dfrac{\partial f}{\partial y}=-8x\cos y+\dfrac{\mathrm dg}{\mathrm dy}=4y-8x\cos y$

$\implies\dfrac{\mathrm dg}{\mathrm dy}=4y$

$\implies g(y)=2y^2+C$

$\implies f(x,y)=\boxed{-8x\sin y+2y^2+C}$

For (A) and (C), we have $f(0,0)=0$ , which makes $C=0$ for both.

a jug holds 4 quarts How many liters of milk dose the jug hold ? round your answer to the nearest hundredth of a liter 1 L=1.06

svetoff [14.1K]

Answer:

Please read the explanation to clarify.

Step-by-step explanation:

What you would have to do is multiply 1.06 by 4 to get 4.24. However, if you search up the exact conversion on g00gle, "how many liters are in 4 quarts?", you get the exact number of 3.78541, which can be rounded to 3.78. I believe if this is more of an exam thing, you should go with the first answer I gave, 4.24, and show how you multiplied to show your work. However, if you would like to use the second answer, it is completely up to you. Either way, I hope this helped, and if you have any further questions please don't hesitate to let me know. :)
