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!!!

Maulik bought two horses at Rs 40,000 each. He sold one horse at 15% gain, but he to sell the second horse at a loss. If he had

givi [52]

Answer:

Answer is selling price of second horse is Rs 30400.

Step-by-step explanation:

Maulik bought one horse at Rs 40000 and sold it with a gain of 15%

So the selling price of one horse will be 40000+15% of 40000

= 40000+6000

= Rs 46000

Second horse is costing Rs 40000 and had suffered a loss of Rs 3600 on selling both so selling price of both will be = 40000×2-3600

= 80000-3600

= 76400

Now selling price of second horse will be selling price of both - selling price of first = 76400-46000 = Rs 30400

20% of the patron's order the chef's special. The probability that 2 out of the next ten customers will order the chef's special

kotegsom [21]

Answer:

$P(x =2) = 0.3020$

Step-by-step explanation:

Given

$p =20\% = 0.20$

$n = 10$

Required

$P(x = 2)$

This question is an illustration of binomial distribution where:

$P(X = x) = ^nC_x * p^x * (1 - p)^{n-x$

So, we have:

$P(x =2) = ^{10}C_2 * 0.20^2 * (1 - 0.20)^{10-2}$

$P(x =2) = ^{10}C_2 * 0.20^2 * 0.80^8$

This gives

$P(x =2) = \frac{10!}{(10 - 2)!2!} * 0.20^2 * 0.80^8$

$P(x =2) = \frac{10!}{8!2!} * 0.20^2 * 0.80^8$

Expand

$P(x =2) = \frac{10*9*8!}{8!2*1} * 0.20^2 * 0.80^8$

$P(x =2) = \frac{10*9}{2} * 0.20^2 * 0.80^8$

$P(x =2) = 45 * 0.20^2 * 0.80^8$

$P(x =2) = 0.3020$
