The formula for finding the area of a rug: $A = s^2$

Plugging in the values we know, we can solve for s.

$79 = s^2$

Take the square root of both sides.

$\sqrt{79} = s$

$\sqrt{79}$ is approximately equal to 8.89

So, 8.89 feet is the answer.

Answer:

The answer is 286 dollars.

Step-by-step explanation:

To find the 5% of a number is to multiply it by 0.05. 286x0.05 is 14.3

286+14.3 is equal to approximately 300 dollars.

Iiana started to evaluate the function f(x)=2x^2-3x+7 for theinput value 2

Vitek1552 [10]

Answer:

The output for x = 2 is

$\therefore f(2)=9$

Step-by-step explanation:

Function:

A function is like a machine that gives an output for a given input.

A function has an independent variable which is called the input of the function.

The output for a given input is called the dependent variable.

Here. 'x' independent variable

f(x) is the function dependent variable

$f(x)=2x^{2}-3x+7$

So Put x = 2 in the f(x) we get

$f(2)=2(2)^{2}-3(2)+7= 2\times 4 -6 +7 = 8+1=9$

The output for x = 2 is

$\therefore f(2)=9$

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!!!
