Answer:

x = \frac{28}{5}

Step-by-step explanation:

x + \frac{2}{5} = 6

x + \frac{2}{5} - \frac{2}{5} = 6 - \frac{2}{5}

x = \frac{28}{5}

Rewrite the following expression.
faust18 [17]

We have been given the expression

x^{\frac{9}{7}}

We have the exponent rule

x^{\frac{a}{b}}= x^{a^{(\frac{1}{b})}}

Using this rule, we have

x^{\frac{9}{7}}= x^{9^{(\frac{1}{7})}}

Now, using the fact that x^{\frac{1}{n}}=\sqrt[n]{x}, we get

x^{\frac{9}{7}}= \sqrt[7]{x^9}\\
\\
x^{\frac{9}{7}}=\sqrt[7]{x^7\times x^2}\\
\\
x^{\frac{9}{7}}=x\sqrt[7]{x^2}

D is the correct option.

Evaluate the triple integral. 5x dv, where e is bounded by the paraboloid x = 7y2 + 7z2 and the plane x = 7. e
Mrac [35]

Convert to cylindrical coordinates:

x=x

y=r\cos\theta

z=r\sin\theta

Then E is the set of points (r,\theta,x) such that 0\le r\le1, 0\le\theta\le2\pi, and 7y^2+7z^2\le x\le7 or 7r^2\le x\le7.

Now

\displaystyle\iiint_E5x\,\mathrm dV=5\int_0^{2\pi}\int_0^1\int_{7r^2}^7xr\,\mathrm dx\,\mathrm dr\,\mathrm d\theta=\boxed{\frac{245\pi}3}
