What is the relationship with 0.04 and 0.004
sattari [20]
Well,

You could say that 0.04 is greater than 0.004.
0.04 > 0.004

You could be more specific and say how much greater 0.04 is compared to 0.004.
0.04 = 10(0.004)

You can also make general conclusions about the two numbers.

"0.04 and 0.004 both are less than 1."

"Both numbers have fractional forms that can be simplified."

"Both numbers have a zero to the left of the decimal point."

And so on and on.

Which of the following ordered pairs represents the solution to the system given below? (4 points)
marta [7]

Answer:

(10, 0)

Step-by-step explanation:

(10, 0) satisfies both of the system equations:  2(10) + 0 = 20 and 4(10) - 0 = 40.

(0, 10) does not.

(4, 2) does not.

(10, -10) does not.

Evaluate the surface integral. ∫∫s (x2 + y2 + z2) ds s is the part of the cylinder x2 + y2 = 16 that lies between the planes z =
KonstantinChe [14]
Decompose the surface into three components, \mathbf r_1,\mathbf r_2,\mathbf r_3, corresponding respectively to the cylindrical region and the top and bottom disks:

\mathbf r_1(u,v)=\begin{cases}x(u,v)=4\cos u\\y(u,v)=4\sin u\\z(u,v)=v\end{cases}
where 0\le u\le2\pi and 0\le v\le5,

\mathbf r_2(u,v)=\begin{cases}x(u,v)=u\cos v\\y(u,v)=u\sin v\\z(u,v)=0\end{cases}
where 0\le u\le4 and 0\le v\le2\pi, and

\mathbf r_3(u,v)=\begin{cases}x(u,v)=u\cos v\\y(u,v)=u\sin v\\z(u,v)=5\end{cases}
where 0\le u\le4 and 0\le v\le2\pi.

For the cylinder, we have

\dfrac{\partial\mathbf r_1}{\partial u}\times\dfrac{\partial\mathbf r_1}{\partial v}=\langle4\cos u,4\sin u,0\rangle\implies\left\|\dfrac{\partial\mathbf r_1}{\partial u}\times\dfrac{\partial\mathbf r_1}{\partial v}\right\|=4

and the integral over this surface is

\displaystyle\iint_{\text{cyl}}(x^2+y^2+z^2)\,\mathrm dS=4\int_{v=0}^{v=5}\int_{u=0}^{u=2\pi}((4\cos u)^2+(4\sin u)^2+v^2)\,\mathrm du\,\mathrm dv
=\displaystyle320\int_{u=0}^{u=2\pi}\mathrm du+8\pi\int_{v=0}^{v=5}v^2\,\mathrm dv
=640\pi+\dfrac83\pi(125)
=\dfrac{2920\pi}3

Bottom disk:

\dfrac{\partial\mathbf r_2}{\partial u}\times\dfrac{\partial\mathbf&#10; r_2}{\partial v}=\langle0,0,u\rangle\implies\left\|\dfrac{\partial\mathbf r_2}{\partial &#10;u}\times\dfrac{\partial\mathbf r_2}{\partial v}\right\|=u

and the integral over the bottom disk is

\displaystyle\iint_{z=0}(x^2+y^2+z^2)\,\mathrm dS=\int_{v=0}^{v=2\pi}\int_{u=0}^{u=4}u((u\cos v)^2+(u\sin v)^2)\,\mathrm du\,\mathrm dv
=\displaystyle2\pi\int_{u=0}^{u=4}u^3\,\mathrm du
=128\pi

The setup for the integral along the top disk is similar to that for the bottom disk, except that z=5:

\displaystyle\iint_{z=5}(x^2+y^2+z^2)\,\mathrm &#10;dS=\int_{v=0}^{v=2\pi}\int_{u=0}^{u=4}u((u\cos v)^2+(u\sin &#10;v)^2+5^2)\,\mathrm du\,\mathrm dv
=\displaystyle2\pi\int_{u=0}^{u=4}(u^3+25u)\,\mathrm du
=528\pi

Finally, the value of the integral over the entire surface is the sum of the integrals over the component surfaces:

\displaystyle\iint_S(x^2+y^2+z^2)\,\mathrm dS=\frac{2920\pi}3+128\pi+528\pi=\dfrac{4888\pi}3
