Find the volume of the solid under the plane 3x+2y−z=0 and above the region enclosed by the parabolas y=x^2 and x=y^2.
Yuri [45]

The region in the <em>x</em>-<em>y</em> plane is the set of points

R=\{(x,y)\mid0\le x\le 1,x^2\le y\le\sqrt x\}

The height of the solid falls between the <em>x</em>-<em>y</em> plane (for which <em>z</em> = 0) and the equation of the plane, <em>z</em> = 3<em>x</em> + 2<em>y</em>.

So the volume is

\displaystyle\int_0^1\int_{x^2}^{\sqrt x}\int_0^{3x+2y}\mathrm dz\,\mathrm dy\,\mathrm dx

=\displaystyle\int_0^1\int_{x^2}^{\sqrt x}(3x+2y)\mathrm dy\,\mathrm dx

=\displaystyle\int_0^1(3x^{3/2}+x-3x^3-x^4)\,\mathrm dx

=\displaystyle\frac65+\frac12-\frac34-\frac15=\boxed{\dfrac34}

An issue of Taunton's Fine Woodworking included plans for a hall stand. The total height of the stand is 5912 59 1 2 inches. If
evablogger [386]

The length if the upper portion of the stand is 33. 56 inches

<h3>How to determine the length</h3>

The formula for the finding the length is given thus;

Total height = length of upper portion + length of base

Where

Length of base = 257/16

Total height = 591/2

Length of upper portion = total height - length of base

= 118/2 - 407/16

= 59 - 25. 44

= 33. 56 inches

Thus, the length if the upper portion of the stand is 33. 56 inches

I don't like mango's but my brother gave me 10,000 mango's and I have to gave my sister 5,000. And my mother gave me $5,000 to s
Alika [10]

Answer:

10,000/2 = 5,000

You would have 5,000

Your sister would also have 5,000

5,000/2 = $2,500

So by splitting the number of mangos your brother gave you, you and your sister will both have 5,000 mangos. As for the money, you and your sister will each have $2,500 after splitting it. I'm not 100% sure what you're asking for but hey, maybe if you give the sister the rest of the mangos you wont have to split the money at all LOL.
