30 inches.
When trying to find the perimeter of a rectangle, add the lengths of all of the sides. So, 5 + 5 + 10 + 10 = 30.
5 + 3 + -4 + 3 + - 5+ -4 +-2 = -4
Sure, what's the question?
4x^2-9=4(x^2-9/4)=4(x-3/2)(x+3/2) i think that is correct answer.
Denote the circle of radius 
by 
. is simple and closed, so by Green's theorem the line integral reduces to a double integral over the interior of (call it 
):
is a circle of radius , so we can write the double integral in polar coordinates as
a. For 
, we have
b. Let 
denote the integral with unknown parameter ,
By the fundamental theorem of calculus,
has critical points when
If 
, then line integral is 0, so we ignore that critical point. For the other two, we would find 
.
