Check where the first-order partial derivatives vanish to find any critical points within the given region:
The Hessian for this function is
with 
, so unfortunately the second partial derivative test fails. However, if we take 
we see that 
for different values of 
; if we take 
we see 
takes on both positive and negative values. This indicates (0, 0) is neither the site of an extremum nor a saddle point.
Now check for points along the boundary. We can parameterize the boundary by
with 
. This turns into a univariate function 
:
At these critical points, we get
We only care about 3 of these results.
So to recap, we found that attains
- a maximum value of 4096 at the points (0, 8) and (0, -8), and
- a minimum value of -1024 at the point (-8, 0).
Answer:
no
Step-by-step explanation:
This is simple long multiplication. 347 x 270 is 93,690. Then you divide this number by the amount of acres, in this case, 3. So 93,690/3 is 31,230. Hope this helped
