Divide 50 and 20 and you get 2.5 then multiply that with 8 and you’ll get 20

What on earth is 7 + √(x - 1) = 2?<br> I'm confused...
Gala2k [10]

Answer: x = 26

Step-by-step explanation:

Let's go step by step.

7 + \sqrt{x-1} = 2\\\sqrt{x-1} = -5\\x-1 = (-5)^2 \\x-1 = 25\\x = 26

Check your answer.

7 + \sqrt{26-1} = 2\\ 7+5 = 2\\12 = 2

That clearly doesn't work, showing how it has no solution.

^The answer above explained it better than me :P

Set up a triple integral in spherical coordinates to compute the volume of the region inside the sphere x² + y² + z² = 4 and abo
Mademuasel [1]

The plane meets the sphere in the cylinder

z=1 \implies x^2+y^2+1^2 = 4 \implies x^2+y^2 = 3 = \left(\sqrt3\right)^2

In spherical coordinates, the plane has equation

z = \rho\cos(\phi) = 1 \implies \rho = \sec(\phi)

and since

\begin{cases}x = \rho\cos(\theta)\sin(\phi) \\ y=\rho\sin(\theta)\sin(\phi)\end{cases} \implies x^2+y^2 = \rho^2 \sin^2(\phi)

the cylinder has equation

\rho^2 \sin^2(\phi) = 3 \implies \rho = \sqrt3 \, \csc(\phi)

The plane and cylinder thus meet when

\sec(\phi) = \sqrt3\,\csc(\phi) \implies \tan(\phi) = \sqrt3 \implies \phi = \dfrac\pi3

So, the volume of the region is given by

\displaystyle \boxed{\int_0^{2\pi} \int_0^{\pi/3} \int_{\sec(\phi)}^2 \rho^2 \sin(\phi) \, d\rho \, d\phi \, d\theta}
