Determine whether or not f is a gradient vector field. if it is, find a function φ such that f = ∇φ. (if the vector field is not

MArishka [77]

$\mathbf f(x,y)=(2x-6y)\,\mathbf i+(-6x+10y-7)\,\mathbf j$

For $\mathbf f$ to be the gradient of some scalar function $\varphi(x,y)$ , we need to find $\varphi$ that satisfies

$\dfrac{\partial \varphi}{\partial x}=2x-6y$
$\dfrac{\partial \varphi}{\partial y}=-6x+10y-7$

From the first PDE, it follows that (upon integrating with respect to $x$ )

$\varphi(x,y)=x^2-6xy+g(y)$

Differentiating with respect to $y$ yields

$\dfrac{\partial\varphi}{\partial y}=-6x+10y-7=-6x+\dfrac{\mathrm dg}{\mathrm dy}$
$\implies\dfrac{\mathrm dg}{\mathrm dy}=10y-7\implies g(y)=5y^2-7y+C$

$\implies\varphi(x,y)=x^2-6xy+5y^2-7y+C$

Answer:

1/10

Step-by-step explanation:

Julie read 5/10 in the morning and had 4/10 left to read after what she read at night. At night, she read ...

1 - 1/2 -2/5 = 10/10 -5/10 -4/10 = 1/10

Julie read 1/10 of the book at night.

slava [35]

Answer: A) y = 6x +3

Step-by-step explanation:

Let x represent the number of hours. $6 per hour can now be written as 6x.

Now, we must account for the $3 flat, fee and add it to 6x, getting 6x + 3
