Answer:
m=0
Step-by-step explanation:
<em><u>mx²+2x-1=0</u></em>
if x=1/2 then
m(1/2)² +2(1/2)-1=0
m/4+1-1=0
m/4=0
m=0
<span>(1 km x 1,000m) </span>÷ 850 m/s = 1.18 s

Converting to spherical coordinates, we have

On the other hand, we can parameterize the boundary of

by

with

and

. Now, consider the surface element



So we have the surface integral - which the divergence theorem says the above triple integral is equal to -


as required.
Answer:

Step-by-step explanation:
You can multiply on the upper and bottom part by the same number without changing the fraction so 
-1+z because 7-8 would be -1 and positive 3-3 would just be the variable after
