Find the flux of the vector field F = 〈e-z,4z,6xy) across the curved sides of the surface S = {(x,y,z): z= cos y, lys π, 0sxs4}

Len [333]

I'll go ahead and assume you meant to say that S is the surface given by

$S = \left\{(x,y,z) \mid z = \cos(y)\text{ with } 0\le y\le \pi\text{ and }0\le x\le4\right\}$

This immediately gives us a parameterization for the surface,

$\vec r(x, y) = \left\langle x, y, \cos(y)\right \rangle$

The upward-pointing normal vector to this surface is then

$\vec n = \dfrac{\partial\vec r}{\partial x} \times \dfrac{\partial\vec r}{\partial y} = \left\langle0,\sin(y),1\right\rangle$

Then the flux of $\vec F(x,y,z) = \left\langle e^{-z}, 4z, 6xy\right\rangle$ across S is

$\displaystyle \iint_S \vec F(x,y,z)\cdot\mathrm d\vec s = \int_0^4\int_0^\pi \vec F(x,y,\cos(y))\cdot\vec n\,\mathrm dy\,\mathrm dx \\\\ = \int_0^4\int_0^\pi \left\langle e^{-\cos(y)},4\cos(y),6xy\right\rangle \cdot \left\langle0,\sin(y),1\right\rangle \,\mathrm dy\,\mathrm dx \\\\ = \int_0^4\int_0^\pi (4\sin(y)\cos(y)+6xy)\,\mathrm dy\,\mathrm dx \\\\ = 2 \int_0^4\int_0^\pi (\sin(2y) + 3xy)\,\mathrm dy\,\mathrm dx = \boxed{24\pi^2}$

Total price : $135,700

Down payment: 20% of total price

Closing costs : 3% of total price

The Colburns will have to borrow 23% of the total price.

A coffee house sells a blended coffee that is made using a $6-per-pound grade and a $4.50 per-pound Grade. If 5 pounds of this b

sineoko [7]

Answer:

3 lbs of $6 coffee
2 lbs of $4.50 coffee

Step-by-step explanation:

Let x represent the number of pounds of $6 coffee. Then the total cost of the mix is ...

6x + 4.50(5 -x) = 27

1.5x +22.50 = 27.00 . . . . . . simplify

1.5x = 4.50 . . . . . . . . . . . . . . subtract 22.50

x = 3 . . . . . . . . . . . . . . . . . . . .divide by 1.5; pounds of $6 coffee

5 -x = 2 . . . . . . . . . . . . . . . . . pounds of $4.50 coffee

3 pounds of $6 coffee and 2 pounds of $4.50 coffee were used in the mix.
