3^4 means 3 to the 4th power.
This means that you would multiply 3 by itself 4 times
It would look like this...3*3*3*3
3^4=81

Hello!

When a number is "powered" by another number, it usually means to multiply itself by the amount of times the powering number is worth. For example, when 3 is powered by 4 (3^4) it means that you need to multiply 3 by itself 4 times. So...

3*3*3*3

One you've powered 3 by 4, your answer should be 81

I hope this helps!

Use a table of signs to solve the inequality

bulgar [2K]

The interval of the provided inequality expression is -5/9 to the infinity [(-5/9),∞) using the table of signs to solve the inequality.

<h3>What is the inequality equation?</h3>

Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.

The inequality given in the problem is,

$4x + \dfrac{5}{9} - 3x \geq 0$

Simplify the equation first by adding the same terms,

$4x + \dfrac{5}{9} - 3x \geq 0\\4x - 3x+ \dfrac{5}{9} \geq 0\\x+ \dfrac{5}{9} \geq 0\\x\geq-\dfrac{5}{9}$

Now in this case, if the value x is ranges from -5/9 to infinity.

Thus, the interval of the provided inequality expression is -5/9 to the infinity [(-5/9),∞) using the table of signs to solve the inequality.

Let w = x2 + y2 + z2, x = uv, y = u cos(v), z = u sin(v). use the chain rule to find ∂w ∂u when (u, v) = (9, 0).

jasenka [17]

By the chain rule,

$\dfrac{\partial w}{\partial u}=\dfrac{\partial w}{\partial x}\cdot\dfrac{\partial x}{\partial u}+\dfrac{\partial w}{\partial y}\cdot\dfrac{\partial y}{\partial u}+\dfrac{\partial w}{\partial z}\cdot\dfrac{\partial z}{\partial u}$
$\dfrac{\partial w}{\partial u}=2xv+2y\cos v+2z\sin v$

We also have $x(9,0)=0$ , $y(9,0)=9$ , and $z(9,0)=0$ , so at this point we get

$\dfrac{\partial w}{\partial u}(9,0)=2\cdot9\cdot\cos0=18$
