Answer:
The value of dz/dx is 27x^2 + 2y
Step-by-step explanation:
We have to given the function z = 9x^3 - 4y^2 + 2xy and we have to find the partial derivative of the given function. In the given function, we have to find partial derivation with respect to x. Therefore, the other values will be considered as constant and during the partial derivation, the constant value will become zero.

Therefore, the value of dz/dx is 27x^2 + 2y
If this is in value, you would have $5,060. If you mean bills it would be 560.
Answer:
31. 20
Step-by-step explanation:
Each class had 40 students right?...so
4 caring=40-36
<h3>4caring=4 students</h3>
<h3>4Dutiful=40-40</h3>
=0 (no student had absent for this class)
4excellence=40-29
<h3>=11 students</h3>
4 friendly=40-35
<h3>=5 students</h3>
Now plus all the number together:
4+11+15=
Final answer:20 students
<span>Is it possible for a composite number to have more than one prime factorization?The Answer is Yes. Prime factors are factors of a composite number that are indivisible except by the number 1 or the number itself. it is possible especially for very large numbers. 2&3. No, because as mentioned previously, the default prime factors of numbers are 1</span>
The formula for the number of combinations when choosing "r" objects (or people) from a larger set of "n" objects (or people) is:
combinations = n! / [r! * (n-r)!]
combinations = 34! / [6! * 28!]
combinations = 34*33*32*31*30*29*28! / [6! * 28!]
combinations = 34*33*32*31*30*29 / 6*5*4*3*2
combinations = 34*33*32*31*29 / 4*3*2
combinations = 34*11*4*31*29
combinations = 1,344,904
