Because I've gone ahead with trying to parameterize 
directly and learned the hard way that the resulting integral is large and annoying to work with, I'll propose a less direct approach.
Rather than compute the surface integral over straight away, let's close off the hemisphere with the disk 
of radius 9 centered at the origin and coincident with the plane 
. Then by the divergence theorem, since the region 
is closed, we have
where 
is the interior of . 
has divergence
so the flux over the closed region is
The total flux over the closed surface is equal to the flux over its component surfaces, so we have
Parameterize by
with 
and 
. Take the normal vector to to be
Then the flux of across is
Answer:
B. City P is above sea level and City R is below sea level
Step-by-step explanation:
A. City R is negative meaning it is below sea level however City Q is 0 meaning it is at sea level, so this statement is false.
C. Once again, City P is positive meaning it is above sea level but City Q is 0 meaning it is at sea level, so this statement is false.
D. Like before, City P is above sea level and City Q is at sea level not below, so this is, once again, false.
Answer:
First blank is >=
Second blank is <=
Step-by-step explanation:
At least means the sign is greater than or equal to
No more than means the sign is less than or equal to
Answer:
he travels 249 miles on saturday
Step-by-step explanation:
<u> 62.25 </u> <u> x</u>
1 = 4
you must multiple the distance travled in one hour by the number of hours of driving. In this case 4. This is if he did not change speeds ;)
4 x 62.25 = 249 miles
Hope this helps :) Please mark brainliest if you see fit :)
