Evaluate the integral e^xy w region d xy=1, xy=4, x/y=1, x/y=2
LUCKY_DIMON [66]
Make a change of coordinates:

u(x,y)=xy
v(x,y)=\dfrac xy

The Jacobian for this transformation is

\mathbf J=\begin{bmatrix}\dfrac{\partial u}{\partial x}&\dfrac{\partial v}{\partial x}\\\\\dfrac{\partial u}{\partial y}&\dfrac{\partial v}{\partial y}\end{bmatrix}=\begin{bmatrix}y&x\\\\\dfrac1y&-\dfrac x{y^2}\end{bmatrix}

and has a determinant of

\det\mathbf J=-\dfrac{2x}y

Note that we need to use the Jacobian in the other direction; that is, we've computed

\mathbf J=\dfrac{\partial(u,v)}{\partial(x,y)}

but we need the Jacobian determinant for the reverse transformation (from (x,y) to (u,v). To do this, notice that

\dfrac{\partial(x,y)}{\partial(u,v)}=\dfrac1{\dfrac{\partial(u,v)}{\partial(x,y)}}=\dfrac1{\mathbf J}

we need to take the reciprocal of the Jacobian above.

The integral then changes to

\displaystyle\iint_{\mathcal W_{(x,y)}}e^{xy}\,\mathrm dx\,\mathrm dy=\iint_{\mathcal W_{(u,v)}}\dfrac{e^u}{|\det\mathbf J|}\,\mathrm du\,\mathrm dv
=\displaystyle\frac12\int_{v=}^{v=}\int_{u=}^{u=}\frac{e^u}v\,\mathrm du\,\mathrm dv=\frac{(e^4-e)\ln2}2

What is the value of 1 over 2 x+3.4y when x=3 and y = 4?​
gavmur [86]

Answer:

The value of the given expression is 27.1

Step-by-step explanation:

We are given an expression of two variable x and y.

We need to find the value of expression at x = 3 and y = 4

So first put x = 3 and y = 4 into expression and simplify

1/2 x 3 (3) + 3.4 x 4

➡️ 1/2 x 27 + 13.6

➡️ 27/2 + 13.6

➡️ 13.5 + 13.6

Now, add both of the numbers together. ( as an addition problem)

Therefore, when you ad the 2 together, you get the total of 27.1

in a recent year one United States dollar was equal to about 82 Japanese yen how many Japanese yen are equal to $1,00 $1,000 $10
Yuki888 [10]
In a recent year, one United States dollar was equal to about 82 Japanese. How many Japanese yen are equal $100?$1,000?$10,000 
<span>Given is: </span>

<span>1 USD = 82 Japanese Yen   </span>

<span>Conversion: </span><span>

1.  100 USD x 82 JY / 1 USD = 8, 200 Japanese Yen</span> <span>
2.  1000 USD x 82 JY / 1 USD = 82, 000 Japanese Yen</span> <span>
3.  10, 000 USD x 82 JY / 1 USD = 820, 000 Japanese Yen</span>

HELP ASAP PLEASE !!!!!!!!!!!!!!
Damm [24]

Answer:

Step-by-step explanation:

Think of drawing a right triangle, with the hypotenuse connected to points A and B.  The hypotenuse, or the distance between A and B is 2√10.  2√10 is the same thing as √40.  Thus, because of Pythagorean theorem, a^2 + b^2 = 40. One combination would be a=2 and b = 6 and another would be a = 6 and b = 2.  Thus, the two places point B could be are (3,7) and (7,3).

Hope it helps <3
