Consider the force field and circle defined below.

grin007 [14]

By Green's theorem,

$\displaystyle\int_{x^2+y^2=9}\vec F(x,y)\cdot\mathrm d\vec r=\iint_D\left(\frac{\partial(xy)}{\partial x}-\frac{\partial(x^2)}{\partial y}\right)\,\mathrm dx\,\mathrm dy=\iint_Dy\,\mathrm dx\,\mathrm dy$

where $C$ is the circle $x^2+y^2=9$ and $D$ is the interior of $C$ , or the disk $x^2+y^2\le1$ .

Convert to polar coordinates, taking

$\begin{cases}x=r\cos\theta\\y=r\sin\theta\end{cases}\implies\mathrm dx\,\mathrm dy=r\,\mathrm dr\,\mathrm d\theta$

Then the work done by $\vec F$ on the particle is

$\displaystyle\iint_Dy\,\mathrm dx\,\mathrm dy=\int_0^{2\pi}\int_0^3(r\sin\theta)r\,\mathrm dr\,\mathrm d\theta=\left(\int_0^{2\pi}\sin\theta\,\mathrm d\theta\right)\left(\int_0^3r^2\,\mathrm dr\right)=\boxed0$

Joan is 5 years older than ellen, and 3 years ago the sum of their ages was 17 years. in how many years will joan be 21 years ol

Anna11 [10]

For this case, the first thing we must do is define variables.
We have then:
x: number of years of Joan y: number of years of ellen We now write the system of equations:
$y = x + 5

 (x-3) + (y-3) = 17$
Solving the system we have:
$x = 9

 y = 14$
So that Joan is 21 years old then:
$j + 9 = 21

 j = 21 - 9

 j = 12$
Answer:
joan will be 21 years old in 12 years

A gardener is making a triangular garden. One angle of the garden is 38° and the sides that surround it are 39.5 feet and 78.5 f

sukhopar [10]

It depends because u have to show us the diagram since we have to know if it is opposite or adjacent to the angle! Anyways I think u can solve it on your own! The question might have something to do with trigonometry like cos sin and tan! Remember the area of a triangle is 1/2*base*height

Graph and write solution:<br><br> 2x + 1 = y<br><br> -4x + 6y = -10

PIT_PIT [208]

The graph is shown in figure below

The Solution Set is (-2,-3)

Step-by-step explanation:

We need to graph the equations and writ the solution.

For graphing we need to find the values of x and y.

For that, we need to solve the given equations:

$2x + 1 = y\\-4x + 6y = -10$
