2 min and 7 sec plus 12= 2 min and 19 sec. Add 8 to the number 19, equals 26. It took Juan 2 min and 26 sec to finish.
1 inch × 375 = 375 miles
5³/₄ inches × 375 = 2156¹/₄ miles
If an inch on a map is equal to 375 miles, then 5³/₄ inches on an map is equal to 2156¹/₄ miles.
Answer:

factorise out a and x :

but from general factorization:

a » x
b » 2
therefore:

Answer:



Step-by-step explanation:
The given function is

We need to find first partial derivatives of the function.
Differentiate partially w.r.t. x and y, z are constants.


Differentiate partially w.r.t. y and x, z are constants.


Differentiate partially w.r.t. z and x, y are constants.



Therefore, the first partial derivatives of the function are
.
