Answer:
b = 12
Step-by-step explanation:
a^2 + b^2 = c^2
25 + b^2 = 169
b^2 = 144
b = 12
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.
I'm pretty sure the answer is d • 3 = 48
Answer:
960
Step-by-step explanation:
We need to find 1/5 of 4800, we will do:
4800/5=960
So 960 is our answer.
