Can someone please help me with this.

Answer:

Step-by-step explanation:

Given expression is $|8-6 i|$ .

$|8-6 i|$ is a complex expression.

The value of<em> i </em>is –1.

By definition of absolute value, $|a+b i|=\sqrt{a^{2}+b^{2}}$

Now, substitute $|8-6 i|$ in the above formula.

$\Rightarrow|8-6 i|=\sqrt{8^{2}+(-6)^{2}}$ (since <em>i </em>= –1)

$=\sqrt{64+36}$ (since $8^{2}=64$ and $–6^{2}=36$ )

$=\sqrt{100}$ (Square root of 100 is 10)

= 10

Hence, the value of the expression $|8-6 i|$ is 10.

Verify that the divergence theorem is true for the vector field f on the region

schepotkina [342]

$\mathbf f(x,y,z)=5x\,\mathbf i+xy\,\mathbf j+2xz\,\mathbf k$

$\mathrm{div}(\mathbf f)=\dfrac{\partial(5x)}{\partial x}+\dfrac{\partial(xy)}{\partial y}+\dfrac{\partial(2xz)}{\partial z}=5+x+2x=5+3x$

By the divergence theorem, the flux of $\mathbf f$ across the boundary of $E$ is given by

$\displaystyle\iint_{\mathcal S}\mathbf f\cdot\mathrm d\mathbf S=\iiint_E\mathrm{div}(\mathbf f)\,\mathrm dV$

$=\displaystyle\int_{z=0}^{z=2}\int_{y=0}^{y=2}\int_{x=0}^{x=2}(5+3x)\,\mathrm dx\,\mathrm dy\,\mathrm dz=64$
