A manufacturer makes rectangular blankets in several styles and sizes. The outline of a popular blanket in size A is shown below
nikdorinn [45]

Answer:

(10x + 8) is the polynomial expression for the perimeter of the blanket.

Step-by-step explanation:

The height and width of the rectangular blanket are (2x - 3) cm and (3x + 7) cm respectively.

Now, the perimeter of a rectangle having height h and width w is given by  

P = 2h + 2w

⇒ P = 2(2x - 3) + 2(3x + 7)

⇒ P = 4x - 6 + 6x + 14

⇒ P = 10x + 8.

So, this is the polynomial expression for the perimeter of the blanket. (Answer)

From a group of 8 women and 6 men, a committee consisting of 3 men and 3 women is to be formed. How many different committees ar
murzikaleks [220]

Answer:

(a) 896

(b) 1000

(c) 910

Step-by-step explanation:

Number of women = 8

Number of men = 6

A committee consisting of 3 men and 3 women is to be formed.

(a) 2 of the men refuse to serve together.

Number of men who don't want to serve together = 2

Remaining men = 4

Total ways = Both men who don't want to serve together are not selected + only one of them is selected.

^{8}C_{3}\cdot ^{4}C_{3}+^{8}C_{3}\cdot ^{4}C_{2}\cdot ^{2}C_{1}

896

(b) 2 of the women refuse to serve together.

Number of women who don't want to serve together = 2

Remaining men = 6

Total ways = Both women who don't want to serve together are not selected + only one of them is selected.

^{6}C_{3}\cdot ^{6}C_{3}+^{6}C_{3}\cdot ^{6}C_{2}\cdot ^{2}C_{1}

1000

(c)1 man and 1 woman refuse to serve together.

Ways = Total ways - Both man and woman are select who refuse the serve together

^{8}C_{3}\cdot ^{6}C_{3}-^{5}C_{2}\cdot ^{7}C_{2}

Write a function rule for the table.<br> x ƒ(x)<br> 3 –1<br> 4 0<br> 5 1<br> 6 2
MaRussiya [10]

Answer:

Step-by-step explanation:

When one variable depends on another variable according to a rule it is known as function:

For example if you want an output of 2 and the input value is 4. Then you will subtract 4 from x

We have to find x f(x).

x f(x) =?

f(x) = x-4

Now input value is:  x= 3

x f(x)

3 (x-4)

3 (3-4)

3 -1

Now x= 4

x f(x)

4 (x-4)

4 (4-4)

4 0

Now x=5

x f(x)

5 (x-4)

5 (5-4)

5 1

Now x=6

x f(x)

6 (x-4)

6 (6-4)

6 2 ....
