I found the missing data: 
table:
foot length (in)    Shoe size(S)
8                                   6
8.5                                7
9                                   8
9.5                               9 
10                               10

Choices:
<span>S = x – 2
S = 2x – 10
S = x + 6
S = 2x + 4
</span>
Among the choices, the correct equation is S = 2x - 10

S = 2(8) - 10 = 16 - 10 = 6
S = 2(8.5) - 10 = 17 - 10 = 7
S = 2(9) - 10 = 18 - 10 = 8
S = 2(9.5) - 10 = 19 - 10 = 9
S = 2(10) - 10 = 20 - 10 = 10

DJ Davon is making a playlist for work; he is trying to decide what 12 songs to play and in what order they should be played. If
Marta_Voda [28]

Answer:

3.63 * 10^19

Step-by-step explanation:

Given that :

Number of choices to select = 12

Category available :

Blues - 14

Country - 25

Disco - 21

To select an equal number of song for each category ; then 4 songs will be selected from each :

Using combination :

(14C4 * 25C4 * 21C4)

Since the order matters for the 12 selected songs ; it thus requires 12 permutation

Thus ;

(14C4 * 25C4 * 21C4) * 12!

nCr = n! / (n-r)!r!

Using calculator;

14C4 = 1001 ;

25C4 = 12650

21C4 = 5985

12! = 479001600

Hence,

(1001 * 12650 * 5985) * 479001600

= 36301596217286400000

=3.63 * 10^19

"Complete the square" to convert the equation of each circle to graphing form. Identify the center and the radius.
Reil [10]

Answer:

The center is (-3,2) and the radius is r=2

Step-by-step explanation:

The general equation of the given circle is

x^2+6x+y^2-4y=-9

Add the square of half the coefficient of the linear terms to both sides of the equation to obtain;

x^2+6x+3^2+y^2-4y+(-2)^2=-9+3^2+(-2)^2

x^2+6x+9+y^2-4y+4=-9+9+4

x^2+6x+9+y^2-4y+4=4

The quadratic trinomials in x and y on the left side of the equations are perfect squares.

We factor to obtain;

(x+3)^2+(y-2)^2=4

(x--3)^2+(y-2)^2=2^2

Comparing to:

(x-h)^2+(y-k)^2=r^2

The center is (-3,2) and the radius is r=2
