Step-by-step explanation:
Answer:
Do not forget to round and multiply.
Step-by-step explanation:
You're looking for the extreme values of
subject to the constraint
.
The target function has partial derivatives (set equal to 0)


so there is only one critical point at
. But this point does not fall in the region
. There are no extreme values in the region of interest, so we check the boundary.
Parameterize the boundary of
by


with
. Then
can be considered a function of
alone:



has critical points where
:



but
for all
, so this case yields nothing important.
At these critical points, we have temperatures of


so the plate is hottest at (1, 0) with a temperature of 14 (degrees?) and coldest at (-1, 0) with a temp of -12.
Answer:
Here we don't have the options, so i will answer in a general way.
Every sentence that has the general structure like:
"something is greater than something"
"something is smaller than something"
"Something is no greater than something"
"something is no smaller than something"
There are a lot of other sentences, for example the ones like:
"N is at least equal to M" written as: N ≥ M
"N is at most equal to M" written as: N ≤ M
And there may be other ways to represent inequalities in sentences, but this is the most general way
Then the given sentence:
"One-half + k greater than 18"
This is written as:
1/2 + k > 18
Which is an inequality.
William needs 102.6 fencing in all because 76.9 plus 25.7 equals 102.6, hope this helps!
