By using the concept of function, it can be seen that the given figure does not represents a function.

What is a function?

A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.

There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.

Here the values on the x axis represents the domain and the values on the y axis represents the Range.

From the figure it can be seen that

For x = 2, there are three points on the y axis.

So the point x = 2 maps to different points on the y axis

So this is not a function

Answer:

  3³

Step-by-step explanation:

You want an expression using an exponent to represent the number 3·3·3.

As you know, a coefficient is used to represent repeated addition:

  a + a + a = 3a

The coefficient 3 in the above expression signifies that 'a' appears in the sum 3 times.

Likewise, repeated multiplication can be represented using a specific notation. An exponent signifies the number of times a factor appears in a product:

  a · a · a = a³ . . . . . 'a' is a factor 3 times

You have a sequence of numbers of telephone calls:

  3 the first day

  3·3 the second day

  3·3·3 the third day

The calls on the third day can be represented using an exponent:

  3³

Additional comment

When superscript formatting is not available for the exponent, it is signified by a caret (^). The same number is 3^3 when written in plain text.

As you might expect, a plain text exponent must be enclosed in parentheses if it is other than a single letter or number.

The total amount is $115

let the number of group class be represented by x

first membership plan, Jen can pay $52 per month, plus $3 for each group class she attends

= $52 + $3x

second membership plan, Jen can pay $31 per month plus $4 per class

Answer:

30.9 cubic inches

Step-by-step explanation:

This is a volume question. You multiply 2 3/4, 2 1/4, and 5 inches all together.

First you turn it into an improper fraction and multiply. 11/4*9/4 = 99/16

Then multiply this by 5: 99/16 * 5 = 30.9375

Round to nearest tenth: 30.9

Answer:

90 units²

Step-by-step explanation:

The scale factor of the lengths of the sides of a solid must be squared to to find the ratio of the areas and cubed to find the ratio of the volumes.

For example, if you are given two solids with a scale factor of the lengths of the sides of 2, meaning that the sides of the second solid are twice the length of the sides of the first solid, then the surface area of the second solid is 2² (= 4) times the surface area of the original solid, and the volume of the second solid is 2² (= 8) times the volume of the original solid.

Let's say you have a cube with edge of 1 cm. The volume is (1 cm)³ = 1 cm³.

The surface area is the sum of the areas of the 6 faces which are squares 1 cm by 1 cm. 6 × (1 cm)² = 6 × 1 cm² = 6 cm².

The original cube with edge of 1 cm has a volume of 1 cm³ and total surface  area of 6 cm².

Now double the size of the edge of the cube. The new cube has an edge of 2 cm. The volume is (2 cm)³ = 8 cm³. Each face of the cube is a square 2 cm by 2 cm. The total surface area of the new cube is 6 × (2 cm)² = 24 cm².

The new cube has volume 8 cm³ and total surface area 26 cm².

Compare the edges, surface areas and volumes of the two cubes:

                             Original Cube     Dilated Cube    Ratio new/dilated

Edge                              1 cm                    2 cm                    1:2

Surface area                 6 cm²                 24 cm²                 1:4

Volume                          1 cm³                  8 cm³                   1:8

Now here is your problem.

We start with the ratio of the volumes.

Original solid: 128 u³

Dilated solid: 54 u³

ratio of volumes: 54/128 = 27/64 = 3³/4³

The ratio of volumes is the cube of the ratio of the lengths.

ratio of lengths: 3/4

ratio of area: 3²/4² = 9/16

Surface area of original solid: 160 u² × 9/16 = 90 u²

The percent of the increase in Paulina’s earnings is 15.55%.

The percentage is defined as a ratio expressed as a fraction of 100.

Last month, she earned $520.60. This month, she works overtime and earns $601.30.

The percent of increase = ($601.30 - $520.60)/520.60 x 100%

The percent of increase = (80.7)/520.60 x 100%

The percent of increase = 0.15501 x 100%

Apply the multiplication operation,

The percent of increase = 15.55 %

Thus, the percentage of the increase in Paulina’s earnings is 15.55%.

Each pound of fish and chicken will cost $3.75 and $2.25 respectively

A word problem is a mathematical exercise where significant background information on the problem is presented in ordinary language rather than in mathematical notation

Given that:

1. A customer pays a total of $11.10 for 1.6 pounds of chicken

and 2 pounds of fish.

2. Another customer pays a total of $12.15 for 2.4 pounds of

chicken and 1.8 pounds of fish

Let C and F represent the cost of one pound of chicken and fish respectively

Statement 1:

1.6C + 2F = 11.10  ---- (1)

Statement 2:

2.4C + 1.8F = 12.15  ---- (2)

we have simultaneous equations now, let's solve using the elimination method:

1.6C + 2F = 11.10      ---- (1)

2.4C + 1.8F = 12.15  ---- (2)

2.4 × (1.6C + 2F = 11.10) =     3.84C + 4.8F = 26.64

1.6 × (2.4C + 1.8F = 12.15) =  3.84C + 2.88F = 19.44

                                            ..........................................

                                                           1.92F  = 7.2

Thus, 1.92F  = 7.2

F = 7.2/1.92 = $3.75

Put F = $3.75 into (1):

1.6C + 2F = 11.10

1.6C + 2(3.75) = 11.10

1.6C + 7.5 = 11.10

1.6C = 11.10 - 7.5

1.6C = 3.6

C = 3.6/1.6 = $2.25

From the given graphs the values of 'c' and 'd' are c = -0.84,

d = 0.84.

What is sinusoidal wave?

A mathematical curve defined in terms of the sine trigonometric function, of which it is the graph, is known as a sine wave, sinusoidal wave, or simply sinusoid. It is a smooth periodic function and a particular kind of continuous wave.

Let the graphs of y = cos(x) and y = cos(x/2) are given.

From this graphs we have to find the value of c and d.

First from y = cos(x) to find the value of 'a'.

Consider, the point  [tex](a, \frac{1}{8})[/tex]

⇒

[tex]cos(a) = \frac{1}{8} \\a = cos^-^1(\frac{1}{8})\\ a = 82.82[/tex]

Now to find the value of 'c'.

Plug a = 82.82 in y = cos(x/2).

[tex]cos(\frac{82.82}{2}) = c \\c = -0.84[/tex]

Hence, the value of 'c' is 'c = -0.84'.

Now to find the value of 'd'.

Consider, the point [tex](b, \frac{1}{8})[/tex]

⇒

[tex]cosb = \frac{1}{8} \\b = cos^-^1(\frac{1}{8})\\b = 82.82[/tex]

Now, plug b = 82.82 in y = cos(x/2)

[tex]cos(\frac{82.82}{2}) = d\\ d = 0.84[/tex]

Hence, from the given graphs the values of 'c' and 'd' are c = -0.84,

d = 0.84.

The angles BAX and CDX are equal and the length of CX is 8.2 cm.

What are angles?

An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint. The Latin word "angulus," which meaning "corner," is the source of the English term "angle." The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle.

Given that, the points A, B, C, D lie on a circle and AC and BD intersect at X.

The angles BAX and CDX, they are subtended by the same arc AD, hence, according to the property of angles subtended by the same arc, they are equal.

Thus ∠BAX = ∠CDX

Since, corresponding sides opposite to the equal angles are proportional.

CX/BX = CD/AB

⇒ CX/3.84 = 9.40/4.40

⇒ CX = (9.40*3.84)/4.40

⇒ CX = 8.2

Thus, length of CX is 8.2cm

The angles BAX and CDX are equal and the length of CX is 8.2 cm

Step-by-step explanation:

[tex]2y=3x+10 \implies y=\frac{3}{2}x+5[/tex]

Parallel lines have the same slope, so the slope of the line we need to find is 3/2.

Substituting into point-slope form, the equation is [tex]y+5=\frac{3}{2}(x-2)[/tex].

Answer:

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

7 (x − 3)(2x - 1) = 2x^2 - x - 3x + 3 = 2x^2 - 4x + 3

8 (x-3y) (2x - y) = 2x^2 - yx - 3xy + 3y^2 = 2x^2 - 4xy + 3y^2

9 (2x - y)(x-2y) = x^2 - 3xy + 2y^2 = x^2 - 3xy + 2y^2

The solution of the system of equations is y = 5 and x = 3, and the difference x - y gives:

x - y = -2

Here we have the system of equations:

5x + 3y = 30

-5x - 2y = -25

If we add the two equations we will get:

(5x + 3y) + (-5x - 2y) = 30 + (-25)

y = 5

So just by doing that we found the value of the variable y.

To find the value of x, we can replace the known value of y on one of the equations, doing that we will get:

5x + 3y = 30

5x + 3*5 = 30

5x + 15 = 30

5x = 30 - 15 = 15

x = 15/5 = 3

x = 3

Then the difference x - y gives:

x - y = 3 - 5 = -2
