Answer:
33.89
Step-by-step explanation:
How to Calculate Rounding to the Nearest 100th?
If the digit after hundredth is greater than or equal to 5, add 1 to hundredth. Else remove the digit. Example
124.586
The third digit of right of decimal point is 6
The second digit after decimal point is 8 which is greater than 5
So add 1 to 8
Result = 124.59
If there is such a scalar function <em>f</em>, then



Integrate both sides of the first equation with respect to <em>x</em> :

Differentiate both sides with respect to <em>y</em> :


Integrate both sides with respect to <em>y</em> :

Plug this into the equation above with <em>f</em> , then differentiate both sides with respect to <em>z</em> :



Integrate both sides with respect to <em>z</em> :

So we end up with
