Use spherical coordinates. evaluate xyz dv e , where e lies between the spheres ρ = 4 and ρ = 6 and above the cone ϕ = π/3.

Set

$x=\rho\cos\theta\sin\varphi$

$y=\rho\sin\theta\sin\varphi$

$z=\rho\cos\varphi$

so that the volume element is

$\mathrm dV=\mathrm dx\,\mathrm dy\,\mathrm dz=\rho^2\sin\varphi\,\mathrm d\rho\,\mathrm d\theta\,\mathrm d\varphi$

The integral is then

$\displaystyle\iiint_Exyz\,\mathrm dV=\int_{\varphi=0}^{\varphi=\pi/3}\int_{\theta=0}^{\theta=2\pi}\int_{\rho=4}^{\rho=6}\rho^5\cos\theta\sin\theta\sin^3\varphi\cos\varphi\,\mathrm d\rho\,\mathrm d\theta\,\mathrm d\rho$

$=\displaystyle\left(\int_0^{\pi/3}\sin^3\varphi\cos\varphi\,\mathrm d\varphi\right)\underbrace{\left(\int_0^{2\pi}\cos\theta\sin\theta\,\mathrm d\theta\right)}_0\left(\int_4^6\rho^5\,\mathrm d\rho\right)$

and so evaluates to 0.

"Review your credit report to make sure there are no unauthorized open accounts" action one can take to determine whether his or her identity has been stolen.

Answer: Option D

Explanation:

Fraudsters can use personal details to rob your bank account or run credit card bills, get insurance medical treatment or get a driver's license on your behalf. Anyone with a Social Security number is a possible victim of identity theft. Specialists believe that early identity theft awareness will considerably reduce the harm caused by theft.

The warning signs involve: a strange charge on your credit card bill, credit score is going up or down, a new account one didn’t open on their credit card, Inaccurate medical records etc. The actions which are needed to take immediately to check whether one got victimized or not are: Check your credit card statements and bank account, Run a credit report and Monitor your finances closely.
