Three one thirds + two one thirds

marusya05 [52]

Here's a real answer:

Three one-thirds: 1/3 + 1/3 + 1/3 = 3/3
Two one-thirds: 1/3 + 1/3 = 2/3

3/3 + 2/3 = 5/3 = 1 2/3

Or if you mean:
3 1/3 + 2 1/3, then it is:

5 2/3

Use Stokes' Theorem to evaluate |c F * dr where C is oriented counterclockwise as viewed from above.F(x, y, z) = xyi + 5zj + 7yk

Hunter-Best [27]

Compute the curl of $\vec F$ :

$\vec F(x,y,z)=xy\,\vec\imath+5z\,\vec\jmath+7y\,\vec k\implies\nabla\times\vec F(x,y,z)=2\,\vec\imath-x\,\vec k$

By Stoke's theorem, the (line) integral of $\vec F$ along $C$ is equivalent to the (surface) integral (or flux) of $\nabla\times\vec F$ across $S$ , the oriented surface with boundary $C$ .

Take $S$ to be the part of the plane $x+z=3$ within the cylinder $x^2+y^2=144$ . Parameterize $S$ by

$\vec s(u,v)=u\cos v\,\vec\imath+u\sin v\,\vec\jmath+(3-u\cos v)\,\vec k$

with $0\le u\le12$ and $0\le v\le2\pi$ . Take the normal vector to $S$ to be

$\vec s_u\times\vec s_v=u\,\vec\imath+u\,\vec k$

Then the integral is

$\displaystyle\int_C\vec F\cdot\mathrm d\vec r=\iint_S(\nabla\times\vec F)\cdot(\vec s_u\times\vec s_v)\,\mathrm du\,\mathrm dv$

$=\displaystyle\int_0^{2\pi}\int_0^{12}(2\,\vec\imath-u\cos v\,\vec k)\cdot(u\,\vec\imath+u\,\vec k)\,\mathrm du\,\mathrm dv$

$=\displaystyle\int_0^{2\pi}\int_0^{12}(2u-u^2\cos v)\,\mathrm du\,\mathrm dv=\boxed{288\pi}$

Reflectional symmetry is the quality a design has if it maintains __ when it is reflected across an axis or line of symmetry

Yuliya22 [10]

Answer:

Let me Explain the meaning of term of term reflection symmetry i.e If an image is reflected across a line of symmetry , axis either through X or Y,the two halves of same image are identical or symmetrical or look alike.For example Human body has a line of symmetry, the alphabets A, X, U,E has 1, 2, 1,1 line of symmetry.In polygons Isosceles triangle,equilateral triangle has 1 and 3 lines of symmetry.

So , Reflectional symmetry is the quality a design has if it maintains <u>Symmetry i.e two halves are same i.e identical</u> when it is reflected across an axis or line of symmetry.
