Answer:

10\sqrt{2}

Step-by-step explanation:

The given is a special right triangle with angle measures as follows:

45-45-90

The side lengths for this special right triangle are represented as follows:

a (the side length that sees angle measure 45)

a\sqrt{2} (the side length that sees angle measure 90)

İn the image we can see that one of the side length that sees angle measure 45 is 10

so c, the side length that sees angle measure 90 (hypotenuse),

is equal to

10\sqrt{2}

Solve the two-step equation. -9x + 0.4 = 4 Which operation must be performed to move all the constants to the right side of the
Alexandra [31]

Answer:

x = -0.4

Step-by-step explanation:

We have the equation:

-9x + 0.4 = 4

First, the operation to move all the constants to the right side is subtraction since we would have to subtract 0.4 from each side, let's see this:

-9x+0.4=4\\-9x+0.4-0.4=4-0.4\\-9x=3.6

Now, we have all the constants on the right side of the equation.

Now, the operation we need to perform to isolate the variable is division (since the x has a -9 that is being multiplied by x) we need to do the opposite operation:

-9x=3.6\\\frac{-9x}{-9} =\frac{3.6}{-9} \\x=-0.4

<h3>Thus, the answer to this equation is x= -0.4</h3>

Use the divergence theorem to calculate the surface integral ??s f · ds; that is, calculate the flux of f across s. f(x,y,z = ex
Kamila [148]
\mathbf f(x,y,z)=e^x\sin y\,\mathbf i+e^x\cos y\,\mathbf j+yz^2\,\mathbf k

By the divergence theorem, the surface integral can be evaluated by computing the triple integral

\displaystyle\iint_Sf(x,y,z)\,\mathrm dS=\iiint_V\nabla\cdot\mathbf f(x,y,z)\,\mathrm dV
=\displaystyle\iiint_V\left(\dfrac{\mathrm d\mathbf f}{\mathrm dx}+\dfrac{\mathrm d\mathbf f}{\mathrm dy}+\dfrac{\mathrm d\mathbf f}{\mathrm dz}\right)\,\mathrm dV
=\displaystyle\int_{x=0}^{x=4}\int_{y=0}^{y=3}\int_{z=0}^{z=4}2yz\,\mathrm dz\,\mathrm dy\,\mathrm dx
