OD.
Step-by-step explanation:
is the disk of radius 1 parallel to the 
-plane and lying in the plane 
. Parameterize this surface by
with 
and 
. Take the normal vector to to be
(the orientation doesn't matter because this is a scalar surface integral)
Then
Answer:
Step-by-step explanation:
11. 76x + 23x = 33
99x = 33
x = 33/99 which reduces to 3
12. 140r - 8r - 4r = 216
128r = 216
r = 216/128 which reduces to 27/16
13. 98c - 99c = 1
-1c = 1
c = -1/1
c = -1
14. 104mn + (-84mn) = 36
104mn - 84mn = 36
20mn = 36
mn = 36/20 which reduces to 9/5....I am not sure about this one...I was not sure if u were looking for m or n..so I didn't separate them. But if ur looking for m, it is m = 9/5n...and if ur looking for n, it is n = 9/5m
15. 118j - 234j = 234
- 116j = 234
j = -234/116 reduces to - 117/58
