It is hard to comprehend your question. As far as I understand:
f(x,y) = e^(-x)
Find the volume over region R = {(x,y): 0<=x<=ln(6), -6<=y <= 6}.
That is all I understood. It would be easier to understand with a picture or some kind of visual aid.
Anyways, to find the volume between the surface and your rectangular region R, we must evaluate a double integral of f on the region R.

Now evaluate,

which evaluates to, 5/6 if I did the math correct. Correct me if I am wrong.
Now integrate this w.r.t. y:

So,

I hope this helps you
let's find AB
AB=square root of 2^2+3^2
AB=square root of 13
cosO=2/sqrt13
sinO=3/sqrt13
tgO=3/2
ctgO=2/3
Divide 29.15/265 = 0.11 or 11 percent
Step-by-step explanation:
=2√-28
=2√4×7×-1
=2(2)√7×-1
=4i√7 (i=√-1)

Answer:
Step-by-step explanation:
x(6.75) + (5 - x)(5.50) = 5(6.25)
6.75x + 27.5 - 5.50x = 31.25
1.25x = 3.75
x = 3 lb of seed A
