Find the flux of f = x3 i y3 j z3 k out of the closed surface z = x2 y2 , 0 ≤ z ≤ 5 oriented outward. g
borishaifa [10]

The flux of the given function f = x³i + y³j + z³k is given by f',

f' = 3(x²i + y²j + z²k)

Given, f = x³i + y³j + z³k

we have to find the flux of the given function f = x³i + y³j + z³k

On partial differentiating the function, we get

f' = 3x²i + 3y²j + 3z²k

f' = 3(x²i + y²j + z²k)

So, the flux of the given function f = x³i + y³j + z³k is given by f',

f' = 3(x²i + y²j + z²k)

Hence, the flux of the given function f = x³i + y³j + z³k is given by f',

f' = 3(x²i + y²j + z²k)

Evaluate 3 - (-1) + (-1) - 3.
lara [203]

Answer:

0

Step-by-step explanation:

3 <em><u>-</u></em> (<u><em>-</em></u>1) + (-1) -3 =

Minus and a negative makes it positive. In other words it would be written like this: 3 + 1 <u><em>+</em></u> (<u><em>-</em></u>1) - 3 =

Next step would be making it minus 1, because plus sign and negative makes the number to be subtracted. It would be rewritten like this: <em><u>3 + 1 </u></em>- 1 - 3 =

Then you will simply add 3 and 1, which makes it 4. So it would be rewritten likes this: <em><u>4 - 1</u></em> - 3 =

Then you will simply subtract 1 from 4, which would equal to 3. So it would be rewritten like this: <em><u>3 - 3</u></em> =

Last step, would be subtracting 3 from 3. Whatever is subtracted from itself would always be 0.

So the answer would be 0!

Which of the following represents the factorization of the trinomial below?<br>x2 - 6x +9​
valentinak56 [21]

For this case we must factor the following expression:

x ^ 2-6x + 9

We must find two numbers that, when multiplied, result in 9 and when added, result in -6.

These numbers are -3 and -3.

-3-3 = -6\\-3 * -3 = + 9

Then, the factored expression is of the form:

(x-3) (x-3) = (x-3) ^ 2

Thus, the correct option is option C.

Option C
