<h2>Age Problem</h2><h3>Answer:</h3>

Kassim is 15 years old this year.

<h3>Step-by-step explanation:</h3>

Let k be Kassim's age this year.

Kassim's age after 30 years is k +30. Also, 3 times the age of Kassim is 3k. We are told that after 30 years, Kassim's age will be 3 times as his age. So, k +30 = 3k.

Solving for k:

k +30 = 3k \\ k +30 -3k = 3k -3k \\ -2k +30 = 0 \\ -2k +30 -30 = -30 \\ -2k = -30 \\ \frac{-2k}{-2} = \frac{-30}{-2} \\ k = 15

Answer:

m<BCA+m<BCD=180

Step-by-step explanation:

supplementary means that the angle measures add up to 180°, if you are using the definition of supplementary angles AND you have had a statement saying that two angles are supplementary, ALWAYS follow it with the sum of the measures of those angles equal 180 :)

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!!!
