Step-by-step explanation:

in a rhombus (not rumbus !) all sides are equally long.

that means

7x - 4 = 3x + 12

4x = 8

x = 2

Answer:

Step-by-step explanation:

The sides of a square are equal to each other, it is with the same with rhombus.

With this information, we can Say that DE is equal to line GD, with
DE =7x-4GD=3x+12
7x-4=3x+12\\
Take 3x from both sides.
4x-4=12
Add 4 to isolate X
4x=16
Divide by 4
x=4\\

So we can say that the value of x is 4

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!!!
