The six different types of graphs are frequency distribution graphs, exponential graphs, logarithmic graphs, trigonometric graphs, and statistical graphs (such as bar, pie, and line graphs).

A vertical and horizontal line connect at the origin to form a simple two-dimensional graph. The x axis is horizontal, whereas the y axis is vertical. The x and y axes in basic line graphs are each subdivided into uniformly spaced subdivisions and given integer values.

There are eight primary types of graphs: linear, power, quadratic, polynomial, and they all aid in organising the presentation of data or information.

Any values of x will result in a real value of the quadratic equation f(x), which is written as f(x). Your minimum score is therefore (3,1).

A function's acceptable range of values is referred to as its domain. These numbers serve as representations of the x-values of a function like f. (x). The set of potential values that a function can be applied to is known as its domain. When the x value is inserted, the method returns the value that is contained in this set. A function's definition is Y = f, where x is the independent variable and y is the dependent variable (x). If it is possible to successfully use a value of x to generate a single value of y using the value of x, that value of x .

VAT meaning value added tax that is attached to an item of product while bought by the buyer and also in each stage of production, distribution level. It is almost similar to a sales tax that is paid within the item price.

given, discount allowed = 20% on the market price.

VAT = 10% on the market price.

Buyer paid as VAT = 320 Rs

Assume, market price of radio = X Rs

now amount of discount = 20/100× X = 0.2X

amount of VAT = 10/100×X = 0.1X

it is said that VAT paid by buyer = 320 Rs

now 320 = 0.1X

X = 320 / 0.1 = 3200 Rs

market price of radio = 3200 Rs

The height of the tree is 17.32 feet.

Height is the measurement of a person's or object's vertical distance from the ground. It is usually expressed in units of meters or feet. Height is an important factor in determining physical characteristics, such as BMI, or Body Mass Index. Height can also be used to estimate the age of a person, and to measure the effects of a growth-promoting treatment. Height is also used in many sports, as it is often an advantage for athletes.

Using the tangent formula, the height of the tree is approximately 17.32 feet. To calculate this, take the tangent of 70 degrees (which is 1.19175) and multiply it by the 10 feet of distance.

The result is 11.9175 feet, which when rounded to the nearest hundredth is 17.32 feet.

For the rate of change of 4 the two points will be A(2,8) and B(4,16).

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

Given that the rate of change of the linear function is 4. The coordinates of the two points will be calculated as,

Rate of change = ( y₂ - y₁ ) / ( x₂ - x₁ )

Rate of change = ( 16 - 8 ) / ( 4 - 2 ) = 8 / 2 = 4

Compare the coordinates,

( x₁, y₁ ) = ( 2, 8 )

If A alone can do a piece of work in 6 days and B alone in 8 days, then A and B undertook to do it for $3200 and complete the work in 3 days with the help of C, then C would be paid 400 dollars.

Therefore the answer is $400.

This is a work and time problem that can be solved using the concept of rate of work. Let's call the amount to be paid to C as "x".

A can do 1 piece of work in 6 days. Therefore, his rate of work is 1/6.

B can do 1 piece of work in 8 days. Therefore, his rate of work is 1/8.

Amount of work A and B can do in 3 days is

= 3×(1/6) + 3×(1/8)

= 3×(1/6)×(4/4) + 3×(1/8)×(3/3)

= 12/24 + 9/24

= 21/24

= 7/8

So amount of work C doing is

= 1 - 7/8

= 1/8

As C do 1/8 amount of work, the amount C would receive is

There are seven images are formed If two plane mirrors are positioned at an angle of 45°.

The formula for the number of images formed by two plane mirrors placed at a certain angle is

where n=angle between the mirrors

The most important thing to remember is that every time the number of images formed is only ODD numbers, if the result is even then you need to subtract 1 from that.

if it is odd u need not subtract, since the number of images ever formed is only odd.

so for an angle, of 45° the number of images formed are:

⇒360/45=8

in this case, since the images formed are even u need to subtract 1 from it i.e

8–1=7

One Kung Pao chicken contains 1620 calories. One Big Mac contains 500 calories.

What is an equation?

A mathematical statement made up of two expressions joined by an equal sign is known as an equation. 3x - 5 = 16 is an example of an equation. We get the value of the variable x as x = 7 after solving this equation.

Assume that one Kung Pao chicken content x calories and one Big Mac content y calories.

Given that one Kung Pao chicken and two Big Macs provide 2620 calories.

Two Kung Pao chickens and one Big Mac provide 3740 calories.

Now using the variable finding calories:

One Kung Pao chicken and two Big Macs provide x + 2y calories.

Two Kung Pao chickens and one Big Mac provide 2x + y calories.

The system of equations is:

x + 2y = 2620  ......(i)

2x + y = 3740  .....(ii)

Using the elimination method to solve the given equations.

Multiply equation (i) by 2 and subtract it from equation (ii)

2x + y = 3740

2x + 4y = 5240

(-)  (-)      (-)

_____________

      -3y = -1500

Divide both sides by -3:

y = 500.

Putting y = 500 in equation (i)

The number of people that will attend each game is given as follows:

The number of attendees will be of 500 on the 857th game, which does not make sense in the context of this problem, as a football team plays at most nine home games during a season. (taking the NFL in context).

The logarithmic function for this problem is defined as follows:

[tex]a(g) = 10 - \log_3{(g + 1)}[/tex]

Hence the number of people that will attend the second home game, when g = 2, is given as follows:

[tex]a(2) = 10 - \log_3{(2 + 1)}[/tex]

a(2) = 10 - 1

a(2) = 9.

Hence 9,000 people, as a(g) is measured in thousands.

The number of people that will attend the eight home game is given as follows:

[tex]a(8) = 10 - \log_3{(8 + 1)}[/tex]

a(8) = 10 - 2

a(8) = 8. (8,000, considering the unit of a(g)).

The game in which 500 people will attend is obtained as follows:

[tex]0.5 = 10 - \log_3{(g + 1)}[/tex]

[tex]\log_3{(g + 1)} = 9.5[/tex]

Step-by-step explanation:

There were 24 photos of Simon's motorbike in the album originally.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

Let x be the number of photos of Simon's motorbike in the album originally.

We know that the number of photos of his car became 12, so the number of photos of his car originally was 8.

We also know that the ratio of the number of photos of his car to his motorbike became 3:5.

So the number of photos of his car and his motorbike originally was x-4.

We can set up the following equation:

12/(x-4) = 3:5

We can cross-multiply and simplify to get:

3x - 12 = 60

3x = 60 + 12

3x = 72

x = 72/3

x = 24

Hence, originally there were 24 photos.
