Answer:
The change in volume is estimated to be 17.20 
Step-by-step explanation:
The linearization or linear approximation of a function
is given by:
where
is the total differential of the function evaluated in the given point.
For the given function, the linearization is:

Taking
inches and
inches and evaluating the partial derivatives we obtain:

substituting the values and taking
and
inches we have:

Therefore the change in volume is estimated to be 17.20 
Answer:
m=28
n=21
Step-by-step explanation:
3×4=12
7×4=28
28×1.75=49
12×1.75=21
Answer:
C
Step-by-step explanation:
All real numbers means all numbers positive and negative
Therefore, it would have to be C because the others dont have both positives and negatives for their domain and range reaches
Evaluate this...

the x at the bottom cancels out one of the xs at the top so it will be

Now the one cancels out one of the 1s in the -4 so

Hope this helps :)
