Let m be the capped cylindrical surface which is the union of two surfaces, a cylinder given by x2+y2=49, 0≤z≤1, and a hemispher

maxonik [38]

It seems that the boundary of $M$ is the circle $x^2+y^2=49$ in the plane $z=0$ . By Stokes' theorem,

$\displaystyle\iint_M(\nabla\times\vec f)\cdot\mathrm d\vec S=\int_{\partial M}\vec f\cdot\mathrm d\vec r$

Parameterize $\partial M$ by

$\vec r(t)=(7\cos t,7\sin t,0)$

with $0\le t\le2\pi$ . Then the line integral is

$\displaystyle\int_{\partial M}\vec f(x(t),y(t),z(t))\cdot\mathrm d\vec r=\int_0^{2\pi}(56\sin t,35\cos t,0)\cdot(-7\sin t,7\cos t,0)\,\mathrm dt$

$=\displaystyle\int_0^{2\pi}(245\cos^2t-392\sin^2t)\,\mathrm dt=\boxed{-147\pi}$

Answer:

$\mathrm{A.\:}x+2y=a$

Step-by-step explanation:

In standard form $ax+by=c$ , any point the line passes through will make the inequality true. We can simply use any point given to find the equation of the line:

We can write the following system of equations from two points from the table:

$\begin{cases}d\cdot3a+e\cdot(-a)=f\cdot a\\d\cdot5a+e\cdot(-2a)=f\cdot a\end{cases}$

Solving, we get:

For $a \notin 0$ ,

$d=1,\\e=2,\\f=1$

Therefore, our equation is:

$dx+ey=fa,\\1x+2y=1a,\\\fbox{$x+2y=a$}$ .
