Answer:
7a-2
Step-by-step explanation:
to represent the perimeter of 2a-3 and 2a and 3a+1
The given sides are 2a-3 and 2a and 3a+1
To find out the perimeter we add all the sides
Now combine like terms to add the terms
2a+2a+3a becomes 7a
-3+1 is -2
Now the perimeter becomes
An expression to represents the perimeter is 7a-2

Answer:
x ≈ 2.87
Step-by-step explanation:
We can subtract 6 to put the equation into a form easily solved.
x^2 +2x +1 = 15
(x +1)^2 = 15
x +1 = √15 . . . . . for the greatest solution, we only need the positive root
x = √15 -1 ≈ 2.87
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,
