Use Green's Theorem to evaluate F · dr. C (Check the orientation of the curve before applying the theorem.)F(x, y) = y cos(x) −
Sergeeva-Olga [200]

Notice that <em>C</em> has a clockwise orientation. By Green's theorem, we have

\displaystyle\int_C\mathbf F(x,y)\cdot\mathrm d\mathbf r=-\iint_D\left(\frac{\partial(xy+x\cos x)}{\partial x}-\frac{\partial(y\cos x-xy)}{\partial y}\right)\,\mathrm dx\,\mathrm dy

where <em>D</em> is the triangule region with <em>C</em> as its boundary, given by the set

D=\{(x,y)\mid0\le x\le2\land0\le y\le8-4x\}

So we have

\displaystyle\int_C\mathbf F(x,y)\cdot\mathrm d\mathbf r=-\int_0^2\int_0^{8-4x}((y+\cos x-x\sin x)-(\cos x-x\sin x))\,\mathrm dy\,\mathrm dx

\displaystyle\int_C\mathbf F(x,y)\cdot\mathrm d\mathbf r=-\int_0^2\int_0^{8-4x}y\,\mathrm dy\,\mathrm dx=\boxed{-\dfrac{64}3}

Which equation is graphed in the figure?
kenny6666 [7]

Answer: Option B.


Step-by-step explanation:

1. The equation of the line has the following form:

y=mx+b

Where m is the slope of the line and b is the y-intercept.

2. Therefore, you must solve for y to write the equation in that form:

3y-4x=\frac{7}{2}x+\frac{3}{2}y+6\\\frac{3}{2}y=\frac{15}{2}x+6\\y=\frac{30}{6}y+4\\y=5x+4

3. As you can see, the y-intercept is b=4, therefor, the equation of the option B is the equation graphed in the figure.
