Evaluate ,where e is the solid that lies between the cylinders x^2+y^2=1 and x^2+y^2=16, above the xy-plane, and below the plane
MA_775_DIABLO [31]
Assuming you're just computing the volume, i.e.

\displaystyle\iiint_E\mathrm dV

we should convert to cylindrical coordinates first, setting

\begin{cases}x=r\cos\theta\\y=r\sin\theta\\z=\zeta\end{cases}

so that the volume is given by

\displaystyle\iiint_E\mathrm dx\,\mathrm dy\,\mathrm dz=\int_{\theta=0}^{\theta=2\pi}\int_{r=1}^{r=4}\int_{\zeta=0}^{\zeta=r\sin\theta+4}r\,\mathrm d\zeta\,\mathrm dr\,\mathrm d\theta

which has a value of 60\pi.

If 5 becomes 11 and 12 becomes 25, what does 15 become?
Amiraneli [1.4K]

Answer:

31.

Step-by-step explanation:

5+5 = 10 + 1 = 11

12 + 12 = 24 +1 = 25

15 + 15 = 30 + 1 = 31

I don't know I tried to see if that was the pattern. It checks out math wise.

Write an equation of the line that passes through the points (-9, 4) and (-10,8) in
MrRissso [65]

Answer:

y = -4x - 32

Step-by-step explanation:

First, find the slope using rise over run (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(8 - 4) / (-10 + 9)

4 / -1

= -4

So, the slope is -4. Plug in the slope and a point into y = mx + b, and solve for b:

y = mx + b

4 = -4(-9) + b

4 = 36 + b

-32 = b

Then, plug in the slope and y intercept into y = mx + b

y = -4x - 32 is the equation of the line
