Gizmo is investing in TikTok stock. He plans on adding an additional $250 at the end of every year and the expected monthly rate

Pie

Answer:

15/2

Step-by-step explanation:

The equation would be 425 x .83(12) + 250 because 425 is what he has at first, then times .83 which is what returns back to him each month, which .83 is multiplied by 12 which is how many months that are in a year plus 250 which is what he adds on after each year

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

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

2^x+2=4. yall i got this problem and i dont rlly understand how to do it. Hope yall can help me:)))))))))))))))

Oksi-84 [34.3K]

Answer:

$x=1$

Step-by-step explanation:

Ok, so we start off with $2^x+2=4$

Then, we subtract 2 from both sides so that becomes: $2^x+2-2=4-2$

After that, we simplify to get: $2^x=2$

Finally, the solution becomes: $x=1$
