Answer:

x = 2

Step-by-step explanation:

We know that

The diagonals of a rectangle are of equal length
The diagonals bisect each other

Considering the above we have:

EG = HF = 2JF = 2JH

Substitute the given values and solve for x:

24x - 8 = 2*(8x + 4)
24x - 8 = 16x + 8
24x - 16x = 8 + 8
8x = 16
x = 16/2
x = 2

Set up an equation to show (×+2)×5=y

Masteriza [31]

5x+10 = y

Subtract 10 from both sides.

5x = y - 10

Divide both sides by 5.

x = 1/5y - 2

Plugin 1/5y - 2 for the y.
5(1/5y - 2)
1 - 10 + 10 = y

1 = y

Your Answer(s)
y = 1
x = 1/5y - 2

Determine whether or not F is a conservative vector field. If it is, find a function f such that F = ∇f. (If the vector field is

gavmur [86]

$\nabla f=(ye^x+\sin y)\,\vec\imath+(e^x+x\cos y)\,\vec\jmath$

then

$\dfrac{\partial f}{\partial x}=ye^x+\sin y\implies f(x,y)=ye^x+x\sin y+g(y)$

Differentiating with respec to $y$ gives

$\dfrac{\partial f}{\partial y}=e^x+x\cos y=e^x+x\cos y+g'(y)$

$\implies g'(y)=0\implies g(y)=C$

So $F$ is indeed conservative, and

$f(x,y)=ye^x+x\sin y+C$
