Person 1 played against the other 5 people
Person 2 played against the other 4 people he hadn't played against
Person 3 played against the other 3 people he hadn't played against
Person 4 played against the other 2 people he hadn't played against
Person 5 played against the other 1 person he hadn't played against
Person 6 played againt the other 0 people as he had already played them

a norman window has the shape of a rectangle surmounted by a semicircle. if the perimeter of the window is 25 feet, express the

sp2606 [1]

The area of the window is $\frac{25x}{2} -(1 +\frac{\pi}{2} )\frac{x^2}{2}$

The shape of the Norman window is described as a rectangle surmounted by a semicircle.

Let 'x' be the width of the window.

Then this width corresponds to the diameter of the semicircle.

That is, radius of the semicircle = x/2

Now given the perimeter of the whole window = 25 ft

This perimeter is equal to the sum of 3 sides of the rectangle and the perimeter of the semicircle.

Perimeter of the semicircle = $\frac{2\pi r}{2} = \frac{\pi x}{2}$ , where r is the radius of the semicircle.

Now let 'y' be the length of the window.

Then sum of three sides of the window = 2y + x

So 2y + x + $\frac{\pi x}{2}$ = 25

Therefore, $y =( 25 - x - \frac{\pi x}{2} ) / 2$

Area of the window = Area of the semicircle + Area of the rectangle =

$\frac{\pi x^2}{8} +xy = \frac{\pi x^2}{8} + x( 25 - x - \frac{\pi x}{2} ) / 2\\ = \frac{\pi x^2}{8} + (25x - x^2 - \frac{\pi x^2}{2} ) / 2$

So Area of the window = $\frac{25x}{2} -(1 +\frac{\pi}{2} )\frac{x^2}{2}$

What is the domain of this relation? (16, 1) (0, 19) (7, –19)

ch4aika [34]

Answer:

{ 0 , 7 , 16 }

Step-by-step explanation:

Domain = set of x values

(16,1) x = 16

(0,19) x = 0

(7,-19) x = 7

The set of x values ( domain ) would be

{ 0 , 7 , 16 }

Note: the values of the domain should be put in order from least to greatest
