C(8, 2)    =  28

Only  4 pairs  are opposite

So

P   =    4  / 28   =    1/7

If   1 - sqrt 2  is a root....so is  1 + sqrt 2

And

If  2 + sqrt 5  is a root.....so is 2 - sqrt 5

We have

[ x - ( 1 - sqrt 2) ] [ x - (1 + sqrt 2) ] [ x - (2 +sqrt 5) ] [ x - ( 2 - sqrt 5)]

This  is  a little tedious  to expand  (but not impossible )....I'll  use WolramAlpha here to help out

f(x)   =  x^4 - 6 x^3 + 6 x^2 + 6 x + 1

base  =  2h - 1

height  =  h

Area  = base * height

6  =  (2h - 1)  * h

6  = 2h^2  - h       rearrange  as

2h^2  - h -  6   =   0     factor as

(2h  + 3) ( h - 2)  =  0

The  second  factor set to 0  gives  us what we need

h - 2  =  0

h  =  2 in

b = 2(2) - 1   =  4 - 1   =  3  in

We  have  this

y =  a ( x + 3)  ( x - 6)

And  the point   (0, -72)  is on the  grpah....so we  can  find  "a"  as

-72  =  a  ( 0 + 3)  ( 0 - 6)

-72  =  a  ( 3) ( -6)

-72  = -18a

-72  /-18  =  a  =    4

f(x)  =

4 ( x + 3) ( x - 6)

4 ( x^2  - 3x - 18)

4x^2  - 12x  - 72

the slope would be 1/4 

To determine the slope of the graph of this linear equation, the equation can be manipulated into the slope-intercept form, y=mx+by=mx+b, by solving for yy. First, subtract (3−k)x(3−k)x from both sides of the equation to get −4(3−k)y=−(3−k)x−27−4(3−k)y=−(3−k)x−27. Then divide both sides by −4(3−k)−4(3−k) to get y=−(3−k)x−27−4(3−k)=−(3−k)x−4(3−k)−27−4(3−k)=14x+274(3−k)y=−(3−k)x−27−4(3−k)=−(3−k)x−4(3−k)−27−4(3−k)=14x+274(3−k). The slope is the coefficient of the xx term, or 1414.

Since   the  base  is a square.....a side of the  base =  FC / sqrt (2)  =   16

The slant  height =   sqrt [  (16 / 2)^2  + 7^2 ]   =  sqrt [ 8^2 + 7^2 ] =  sqrt  [ 64 + 49 ]   =

sqrt [ 113  ]  ≈   10.6 cm

so since we know FC is 16sqrt2, the we know the side length is 16, 16^2 + 16^2 = (x)^2, x = 16sqrt2

then we use half the length of the square since we can make a triangle using the midpoint of the square.

7^2 + 8^2 = c^2, c = sqrt113 or roughly 10.63

2x + 2 = 10

x = 4

UZ = VZ = 7.5

WU = 5

Arc QWR ≈ 106.26º

WZ = YZ = 12.5

Area = 12.52pi

Circumference = 25pi

5 x 7 = 35

DB = 12(12 / 16)

arc BD  =  180°

arc DC  =  48°

arc BC  =   arc BD  -  arc DC  

arc BC   =  180  - 48   =    132°

holy cow 9 years and 3 weeks

Note  that triangle ULM  is  similar to triangle  UTV

Since  UV  =  2 *  UM ......then  this  means that

 TV = 2 * LM   ....so....

x + 5  =  2  ( 2x - 14)

x + 5  =   4x  -  28

5 + 28  =   4x   -  x

33  =  3x

33/3   =  x    =   11

So

LM  =   2(11)  - 14   =  22  - 14   =   8

The Law of Sines can be used to solve oblique triangles, which are non-right triangles. According to the Law of Sines, the ratio of the measurement of one of the angles to the length of its opposite side equals the other two ratios of angle measure to opposite side.

lol what am i even doing answering a question 8 years later

12/ 27   =  20  / ( 20  + 3x + 1)     cross-multiply

12  ( 20 + 3x + 1)  =  20 * 27

12 ( 21 + 3x)  =     540

21 + 3x   =   540 / 12

21  +  3x  =  45

3x  =  45  -  21

3x  =   24

x  =  24 / 3   =    8

Let  the distance  from  the parking lot to the beach be  the altitude of the  triangle = A

We  have  this relationship

10 / A  =  A /12           cross-multiply

10 * 12  =  A * A

120  =  A^2

The distance  from the refreshment  stand to  the parking lot is

sqrt  [ A^2  + 12^2 ]   =    sqrt  [  120 + 144 ]  =  sqrt 264  ≈  16.25 m

Using similar triangles

8 is to 12     as   12 is to x + 8

8/12 = 12/(x+8)     cross multiply

8x + 64 = 144

x = 10

Look  at the graph here  : https://www.desmos.com/calculator/gsz05uir66

Line  "l"  forms  a  triangle   with a base of  6  and a  height of 6.....its  area = (6 *6) / 2  =  18

The  area  between  these lines  forms a  triangle  with a base of 3  and a  height of 6....its  area  = (3 * 6)  /2  = 9

The probability  that a selected point  falls between  the lines =  9/ 18  =  1/2  =  .50

Here's  my  best attempt

Total possible products   =  100 * 100  =  10,000   

Look  at  a simple  scenario

Andrew chooses  an odd    ...... the  product is  even  only if Mary chooses  an even number

So......50  even products

Andrew chooses  an even .....the product is  even  no matter what  number  Mary chooses

So...100  even products

So......we  have   50 odds * 50  +   50 evens * 100 =   2500 + 5000  =  7500  even outcomes

so if you are wondering what 3x5 is then you are looking at the right answer. So let's say you start out with counting by 3's so 3,6,9,12,15. Yes it goes to 15. But that is not the answer. So let's try counting by 5's. So 5,10,15. Ok so that's it. There is your answer three times five is fifteen. Now if you could hear5 me that would be great. And I am a girl. But my name sounds like a boy but I am a girl.

BD = 20(20 / 16) 

Okay, thank you for letting me know.
