Answer:
x=-4
Step-by-step explanation:
3x+1=-11
subtract one from both sides
3x+1= -11
-1 -1
3x=-12
divide by 3 on both sides
3x/3 -12/3
x= -4
-4
/3 /3
x = -4
the median is 43
I gather you're supposed to compute the integral of over a surface that is the part of the parabolic cylinder with and .
We can parameterize by
with the given constraints on and . Take the normal vector to to be
so that the surface element is
Then in the integral, we have
x= -2
