Derivative with respect to x: 
Derivative with respect to y: 
Derivative with respect to z: 
Step-by-step explanation:
We can calculate three derivatives for this function: the derivative with respect to x, the derivative with respect to y, and the derivative with respect to z.
We start with the derivative with respect to x:

Then we calculate the derivative with respect to y:

Finally, we calculate the derivative with respect to z:

Answer:
see below
Step-by-step explanation:
The three sides add to 51
n + 4n-4 + 4n-8 = 51
9n -12 = 51
9n = 63
n = 7 4n-4 = 24 4n-8 = 20
The area of the square is greater than the circle: the area of the circle is pi(r)^2 while the area of the square is length times width. The area of the circle is about 12.5 while the area of the square is 16.
C- is either a or c
Explanation -
$208
Steps:
10% of 130 is 13
13 x 6 would give you 60%
13 x 6 is 78
60% = 78
130 + 78 = 208
