О O

Answers

Answer 1

Answer: D. {(0, - 4), (1, - 4), (2, 4), (3, 4), (4, - 4)}

Step-by-step explanation:

A relation R is said to be a function if for each input value there exists only one unique output value.

In (x,y)  , x= Input value , y= output value.

A. {(-1, - 4), (-1,0), (- 1,5), (- 1, 7), (-1,9)}

Here, -1 has two output values -4 and 0.

So it is not a function.

B. (-2, - 4), (-1,7), (1, - 1), (1, 1), (3,9)}

Here, 1 has two output values -1 and 1.

So it is not a function.

C. {(-4,9), (- 3, 1), (- 2, 3), (- 2, 12), (0, 6) }

Here, -2 has two output values 3 and 12.

So it is not a function.

D. {(0, - 4), (1, - 4), (2, 4), (3, 4), (4, - 4)}

here, each input value has an unique output value.

Hence, D. option is correct.

The area of this rectangle is 10cm2, find the value of x and use it to find the length and the width of the rectangle.
If the length of a rectangle is three time the width and it’s perimeter is 24 cm, what is its area?

Answers

Answer:

The area of this rectangle is 10cm2, find the value of x and use it to find the length and the width of the rectangle.

If the length of a rectangle is three time the width and it’s perimeter is 24 cm, what is its area?

Length and width of the rectangle are 4 cm and 2.5 cm respectively.

Given in the picture,

A rectangle with the area of 10 cm².Expressions representing the lengths of the rectangle as

        (4x + 2) cm and (10x - 1) cm

By the property of a rectangle, measure of opposite sides of a rectangle are always equal,

(4x + 2) = (10x - 1)

(4x + 2) - 4x = (10x - 1) - 4x

2 = 6x - 1

2 + 1 = (6x - 1) + 1

3 = 6x

[tex]x=\frac{3}{6}=\frac{1}{2}[/tex]

Now we can get the length of the given rectangle by substituting the value of 'x' in (10x - 1) or (4x + 2).

(10x - 1) = [tex]\frac{10}{2}-1[/tex]

            = 4 cm

Since, area of a rectangle is given by the expression,

Area = Length × width

By substituting the values in the expression,

10 = 4 × width

Width = [tex]\frac{10}{4}[/tex]

           = 2.5 cm

        Therefore, length and width of the rectangle are 4 cm and 2.5 cm respectively.

P and q are points on the line y=2-4X

Draw the line y= 2-4X for vales of x from -2 to 2

Answers

Answer:

`The answer is below

Step-by-step explanation:

P and q are points on the line y=2-4X. complete the coordinates of P and Q, P(0, ) Q( ,0)

Draw the line y= 2-4X for vales of x from -2 to 2

Solution:

The equation of a line is given by:

y = mx + b

Where y and x are variables, m is the slope of the line and b is the y intercept (that is value of y when x = 0).

The line of y = 2 - 4x is drawn by finding the corresponding values of y for x from -2 to 2 and plotting on a graph.

x:   -2      -1       0        1        2

y:   10      6       2       -2       -6

The value P(0, ) Q( ,0)

The y coordinate of point P is gotten by substituting x = 0:

y = 2 - 4(0) = 2

P = (0, 2)

The x coordinate of point Q is gotten by substituting y = 0:

0 = 2 - 4x

4x = 2

x = 0.5

Q = (0.5, 0)

Suppose a chemist combines a 25% acid solution and a 50% acid solution to make 40 L of 45% acid solution. How many liters of each solution did she use? Use the blanks below to fill in your numerical answers.

Answers

Answer:

The number of liters for :

Acid solution a = x = 8 liters

Acid solution b = y = 32 liters

Step-by-step explanation:

Let us represent:

The number of liters for :

Acid solution a = x

Acid solution b = y

Suppose a chemist combines a 25% acid solution and a 50% acid solution to make 40 L of 45% acid solution.

x + y = 40 ...... Equation 1

x = 40 - y

25% × x + 50% × y = 45% × 40

0.25x + 0.5y = 18...... Equation 2

We substitute, 40 - y for x in Equation 2

0.25(40 - y)+ 0.5y = 18

10 - 0.25y + 0.5y = 18

- 0.25y + 0.5y = 18 - 10

0.25y = 8

y = 8/0.25

y = 32 Liters

Solving for x

x = 40 - y

x = 40 - 32

x = 8 Liters.

Hence:

The number of liters for :

Acid solution a = x = 8 liters

Acid solution b = y = 32 liters

Steve is writing about this excerpt from The Jungle Book.

Akela raised his old head wearily:—

"Free People, and ye too, jackals of Shere Khan, for twelve seasons I have led ye to and from the kill, and in all that time not one has been trapped or maimed. Now I have missed my kill. Ye know how that plot was made. Ye know how ye brought me up to an untried buck to make my weakness known. It was cleverly done. Your right is to kill me here on the Council Rock now. Therefore I ask, 'Who comes to make an end of the Lone Wolf?' For it is my right, by the Law of the Jungle, that ye come one by one."

There was a long hush, for no single wolf cared to fight Akela to the death. Then Shere Khan roared: "Bah! What have we to do with this toothless fool? He is doomed to die! It is the man-cub who has lived too long. Free People, he was my meat from the first. Give him to me. I am weary of this man-wolf folly. He has troubled the jungle for ten seasons. Give me the man-cub, or I will hunt here always, and not give you one bone! He is a man—a man's child, and from the marrow of my bones I hate him!"



Steve makes the claim "Akela is willing to give his life for the Law of the Jungle.”

Which evidence from the text best supports this claim?

Below is a set of data about temperatures. The range of a set of data is the distance between the lowest and highest value in the set. What is the range of these temperatures?
9°C, -3°C, 22°C, -5°C, 11°C, 15°C

Answers

Answer:

22-(-5)= 27

Step-by-step explanation:

22 is the highest temp. -5 is the lowest.

The range of the given temperatures is 27.

What is the range of the data set?

"It the difference between the highest and lowest value of the data set."

For given example,

a set of data about temperatures is,

9°C, -3°C, 22°C, -5°C, 11°C, 15°C

First, we arrange the data values in ascending order.

-5°C, -3°C, 9°C, 11°C, 15°C, 22°C

Here, the lowest temperature = -5°C

the highest temperature = 22°C

So, the range of the data set would be,

R = highest temperature value - lowest temperature value

R = 22 - (-5)

R = 22 + 5

R = 27

Therefore, the range of the given temperatures is 27.

An athletics club has junior
(i.e. boy or girl) members and adult members.
The ratio of girls to boys to adults is 3:4:9
and there are 16 more adult members than
junior members. In total, how many members
does the club have

Answers

Answer:

The total number of members are 128 members

Step-by-step explanation:

From the question, mixing the ratio of children to adult, we have ;

7:9

There are 16 more adult members

So if there are x children, then there are 16 + x adults

Thus, the total number of members will be;

16 + x + x = 2x + 16

Now, we have that;

7/16 * (2x + 16) = x

7(2x + 16) = 16x

14x + 112 = 16x

16x-14x = 112

2x = 112

x = 112/2

x = 56

The total number of members is thus;

2(56) + 16 = 128
