I’m pretty sure the answer is D because you need separate the variable V by itself do you divide I from V and then the division changes to IR. If I’m wrong on that, then it’s A

A soundproofing tile is made of 8 identical solid right pyramids with square bases. The length of the whole tile shown is x inch
mylen [45]

Answer:

Option B ⇒ Area of base of each pyramid :

(\frac{x}{4})^2 in^2

Option A ⇒ Volume of pyramid :

\frac{1}{3} x^{2} \cdot y   cm3

Step-by-step explanation:

One side of tile consists of 4 pyramids and since length of whole tile is x,

So, the base length of each pyramid = \frac{x}{4}

⇒ Area of base of each pyramid = side²

⇒ Area =

(\frac{x}{4})^2 in^2

Volume of square based pyramid :

=(Area of base )\cdot \frac{h}{3}\\=\frac{x^2}{3} cm^3

For 1. The correct Option is B

For 2. The correct option is A

F(x, y, z) = yzexzi + exzj + xyexzk,
Ghella [55]
\nabla f(x,y,z)=\mathbf F(x,y,z)\iff\dfrac{\partial f}{\partial x}\,\mathbf i+\dfrac{\partial f}{\partial y}\,\mathbf j+\dfrac{\partial f}{\partial z}\,\mathbf k=yze^{xz}\,\mathbf i+e^{xz}\,\mathbf j+xye^{xz}\,\mathbf k

\dfrac{\partial f}{\partial x}=yze^{xz}
\implies f(x,y,z)=\dfrac{yz}ze^{xz}+g(y,z)=ye^{xz}+g(y,z)

\dfrac{\partial f}{\partial y}=e^{xz}=e^{xz}+\dfrac{\partial g}{\partial y}
\implies\dfrac{\partial g}{\partial y}=0\implies g(y,z)=h(z)

\dfrac{\partial f}{\partial z}=xye^{xz}=xye^{xz}+\dfrac{\mathrm dh}{\mathrm dz}
\implies\dfrac{\mathrm dh}{\mathrm dz}=0\implies h(z)=C

f(x,y,z)=ye^{xz}+C

\mathbf r(t)=(t^2+5)\,\mathbf i+(t^2-1)\,\mathbf j+(t^2-5)\,\mathbf k
\implies\mathbf r(0)=5\,\mathbf i-\mathbf j-5\,\mathbf k
\implies\mathbf r(5)=30\,\mathbf i+24\,\mathbf j+20\,\mathbf k

By the gradient theorem, we have for any path \mathcal C originating at the point (5, -1, -5) and terminating at the point (30, 24, 20),

\displaystyle\int_{\mathcal C}\mathbf F\cdot\mathrm d\mathbf r=f(\mathbf r(5))-f(\mathbf r(0))=f(30,24,20)-f(5,-1,-5)
\implies\displaystyle\int_{\mathcal C}\mathbf F\cdot\mathrm d\mathbf r=24e^{600}+e^{-25}

3x-4y&gt;12
Anvisha [2.4K]

For this case we have the following inequality:

3x-4y> 12

We must find an ordered pair of the form (x, y) that meets the inequality.

Example:

<em>Pair 1: </em>(x, y) :( 0,0)

3 (0) -4 (0)> 12\\0> 12

This pair does not satisfy the inequality.

<em>Pair 2:</em> (x, y) :( 6,1)

3 (6) -4 (1)> 12\\18-4> 12\\14> 12

This pair satisfies the inequality!

Thus, the pair(x, y) :( 6,1) meets the inequality.

Answer:

(x, y) :( 6,1)
