Evaluate the given integral by changing to polar coordinates. sin(x2 y2) dA R , where R is the region in the first quadrant betw

alexira [117]

Answer:

I = 1.47001

Step-by-step explanation:

we have the function

$f(x,y)=sin(x^2y^2)\\$

In polar coordinates we have

$x=rcos\theta\\y=rsin\theta$

and dA is given by

$dA=rdrd\theta$

Hence, the integral that we have to solve is

$I=\int \limt_2^4 \int \limit_0^{\pi /2}sin(r^4cos^2\theta sin^2\theta)rdrd\theta$

This integral can be solved in a convenient program of your choice (it is very difficult to solve in an analytical way, I use Wolfram Alpha on line)

I = 1.47001

Hope this helps!!!

What’s a equivalent expression using prime factorization for the number 254

erik [133]

So prime factorization is what it seems, <u>finding the prime factors of a number.</u> Using prime factorization, we can break down 254 as such:

$\underbrace{254}_{\boxed{2*127}}$

Since 2 and 127 are prime,<u> the prime factorization of 254 is 2 × 127.</u>

Find m<14 if m<13=115º.

salantis [7]

Answer:

115

Step-by-step explanation:

Since line v and line u are parallel:

m<14 and m<13 must be alternate exterior angles and alternate exterior angles has equal measure so the answer is:

m<13 = m<14 = 115.
