Answer:

Hi!

The answer is: 1.804.000 cockroaches are immune.

Step-by-step explanation:

To solve this problem, you can use <em>the rule of three</em>.

     100 ----> 2.200.000 cockroaches  // If 100% is 2.200.000 cockroaches

     82 ----> x cockroaches  // then 82% will be immunes.

Now, multiply 82 by 2.200.000 and divide the result by 100:

x =\frac{82*2.200.000}{100} = 1.804.000

<u>1.804.000 cockroaches are immune.</u>

Use Greens Theorem to evaluate integral x^2ydx - xy^2dy, where C is 0 ≤ y ≤ √9-x^2 with counterclockwise orientation
Ratling [72]

Answer:

Step-by-step explanation:

a circle will satisfy the conditions of Green's Theorem since it is closed and simple.

Let's identify P and Q from the integral

P=x^2 y, and Q= xy^2

Now, using Green's theorem on the line integral gives,

\oint\limits_C {x^2ydx-xy^2dy } =\iint\limits_D {y^2-x^2} \, dA\\\\
