Answer:

b. 56

Step-by-step explanation:

Please consider the complete question.

There are 8 members on a board of directors. If they must form a subcommittee of 3 members, how many different subcommittees are possible?

We will use combinations for solve our given problem.

$^nC_r=\frac{n!}{r!(n-r)!}$ , where,

n = Number of total items,

r = Items being chosen at a time.

For our given scenario $n=8$ and $r=3$ .

$^8C_3=\frac{8!}{3!(8-3)!}$

$^8C_3=\frac{8!}{3!\cdot 5!}$

$^8C_3=\frac{8\cdot7\cdot6\cdot5!}{3\cdot2\cdot1\cdot 5!}$

$^8C_3=8\cdot7$

$^8C_3=56$

Therefore, 56 different subcommittees are possible and option 'b' is the correct choice.

Find the magnitude of wx for w(6 -3 6) and x(6 3 4)<br> A. 2sqrt10<br> B. 35<br> C. 4sqrt2<br> D. 32

gladu [14]

Answer:

$|WX|=2\sqrt{10}$

Step-by-step explanation:

To find the distance between two points in there dimensional coordinate system, we use the formula;

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2}$

The magnitude for w(6 ,-3 , 6) and x(6, 3, 4)

$|WX|=\sqrt{(6-6)^2+(3--3)^2+(4-6)^2}$

$|WX|=\sqrt{(0)^2+(6)^2+(-2)^2}$

$|WX|=\sqrt{0+36+4}$

$|WX|=\sqrt{40}$

$|WX|=2\sqrt{10}$

The correct choice is A.

The smelliness of cheese (denoted by S) can be defined as a function of the number of bacteria in the cheese (denoted by B) and

DedPeter [7]

Answer: OPTION C.

Step-by-step explanation:

Given the following formula:

$S=B*A$

You know that "S" is the smelliness of cheese, "B" is the number of bacteria in the cheese and "A" is the surface area in square centimeters of the cheese.

For example, suppose that there are $3,000\ bacterias$ in a surface area of $60 \ cm^2$ .

Substitute into the formula these values:

$B=3,000\ bacterias\\\\A=60\ cm^2$

And then evaluate:

$S=(3,000\ bacterias)(60\ cm^2)\\\\S=180,000\ bacterias*cm^2$

Therefore, you can conclude that the appropriate measurement unit for "S" is:

$bacterias*cm^2$

Only need help on number 5 and 6

Alborosie

5) since (x-a)^2+(y-b)^2=r^2

plug in (-5,2) as (a,b) and r=3

Making the equation:

(x+5)^2+(y-2)^2=9

6) (x-0)^2+(y-0)^2=r^2

since we have (0,5)

0^2+5^2=r^2

Final equation: x^2+y^2=25

Home Station had a promotion offering $4 off on a gallon of house paint. Write an equation for the cost,C,of 15 gallons paint in

ohaa [14]

Answer:

Therefore the required equation is C = $ 15p - 60

Step-by-step explanation:

i) the price per gallon of paint = $p

ii) promotion offering price per gallon = $(p-4)

iii) cost of 15 gallons at the rate of promotion offering, C = 15(p - 4) = 15p - 60

Therefore the required equation is C = $ 15p - 60
