The relationship between the interior and exterior angles of a polygon is they are supplementary.

What is a regular polygon?

If a polygon has equal sides and angles, it is said to be regular. As a result, an equilateral triangle is a regular triangle, and a square is a regular quadrilateral.

Here,

we have to show how the interior and exterior angles of a polygon relate to each other.

A special rule exists for regular polygons: because they are equiangular, the exterior angles are also congruent, so the measure of any given exterior angle is 360/n degrees.

As a result, the interior angles of a regular polygon are all equal to 180 degrees minus the measure of the exterior angle(s).

Hence, the relationship between the interior and exterior angles of a polygon is they are supplementary.

What is Distance formula?

The distance formula is a mathematical formula used to determine the distance between two points in a plane. The formula is:

d = √((x2 - x1)² + (y2 - y1)²)

"C" and "D" are points in a two-dimensional coordinate system. C is represented by the coordinates (-1, 11) and D is represented by the coordinates (7, -4).

The difference between these two points is the distance between them, which can be calculated using the distance formula:

√((x2 - x1)² + (y2 - y1)²)

Where x1, y1 are the coordinates of point C and x2, y2 are the coordinates of point D.

Substituting the values, we get:

√((7 - (-1))² + (-4 - 11)²) = √((8)² + (-15)²) = √(64 + 225) = √289

Hence, the difference between point C and D is √289 units.

If Police estimate that 20% of drivers do not wear their seatbelts. The police set up a safety roadblock and stopping cars to check for seatbelt use. If the police team stops 30 cars during the first hour,  the standard deviation is 2.191.

Using this formula to find the Standard deviation

Standard deviation = √ Sample size  × Estimated drivers × (1 - Estimated drivers)

Let plug in the formula

Standard deviation = √ 30 × 0.20 × (1- 0.20)

Standard deviation = √ 30 × 0.20 × 0.80

Standard deviation = √ 4.8

Standard deviation = 2.191

The total cost of their stay at the StarWatch camping site will be £108. This includes the special offer of 5 nights for the price of 4.

Lila and Wassim have saved £130 by the time of their holiday. This means they have saved £22 extra.

The line that connects the coordinates (6, 4) and is perpendicular to the line 2xy=5 has the equation =y=1/2x-1.

The general equation for every straight line is y = mx + c, where m is the gradient (or degree of steepness) of the line and c is the y-intercept (the point in which the line crosses the y-axis).

The variables x and y are related to coordinates on the line in the linear equation y = mx + c.

The formula y = mx + c yields a result for y when we enter a value for x.

As y depends on the value of x, it follows that x is an independent variable and y is a dependent variable.

According to our question-

a line equation that is perpendicular to the line 2xy=5 and passes through the point (6, 4)

The slope of the given equation 2x-y=5 is first determined.

The line's equation is y=mx+b. where'm' represents the slope

Hence, The line that connects the coordinates (6, 4) and is perpendicular to the line 2xy=5 has the equation =y=1/2x-1.

We can rewrite one side of the given equation using distributive property.

What is distributive property?

The distributive property states that multiplying the sum of two or more addends by a number yields the same outcome as multiplying each addend separately by the number and combining the resulting products.

A, B, and C are the operands in the formula for the distributive property, which is written as a (b + c) = (a b) + (a c). Here, each term enclosed in a bracket multiplies the number outside of it, and the results are added.

The given equation is: 3(x + 2) = 18

The statement (c) describes that the graph of f is shifted 5 units down to create the graph of g. The solution has been obtained using the concept of vertical translation.

What is translation?

Translation is the act of moving a shape or a figure from one position to another. It is classified into two types:

Now, for a function f(x) we define a vertical translation of N units as:

g(x) = f(x) + N

If N is positive, the translation is upwards.

if N is negative, the translation is downwards.

We are given g(x) = f(x) - 5

This shows that N is negative and therefore, there is translation of 5 units downwards.

Solving the triangle we found the distance between the gazebo and the dock is: 69.34 meters. The answer is explained below:

The first thing to know is that to solve any triangle you must know at least one side and two other elements that can be sides or angles, that is, at least three elements of the six that make up a triangle.

Now, in the problem we know the value of one side (90 m) and 3 angles (see attached image), therefore the calculation of the distance (one side) is very easy if we apply the law of sines:

According to the Law of Sines, the ratio of the length of the sides of a triangle (not a rectangle) and their respective opposite angle sines, is the same value. Then:

d / sen (46°) = 90 m / sen (69 °)  

After, we pass  sen (46°) to the second term of the equation.

d= sen(46°)*90 m / sen (69°)

d = 0,7193*90/ 0,9335

d = 69,34 m

     (x-2)² + ( y + 1)² = 34 is the equation of the circle in standard form.

What is the short definition of a circle?

To put it simply, a circle is a spherical shape without any edges or line segments. In terms of geometry, it has the shape of a closed curve.

                                             The circle's points are set apart from the center by a predetermined amount.

The endpoints of the diameter (7,−4) and (−3,2)

the center of the circle is the midpoint of the diameter.

So, the coordinates of the center  

                      (h,k) = ( 7 + (-3)/2  , -4 +2/2)

                                = ( 4/2 , -1 )

                                 = ( 2 , -1 )

the radius of the circle is just half of the length of the diameter.

So,                 r = 1/2√(-3 -7 )² + ( 2 - (-4))²

                        = 1/2√(10)²  + ( 2 +4 )²

                        = 1/2√100 + 36

                        = 1/2√136

                         = √136/2

                        = 2√34/2

                         = √34

substitute the values of h, k, and r into the standard equation of the circle

                       ( x-h)² + ( y-k)² = r²

                      ( x - 2)² + ( y -(-1))² = (√34)²

According to the information, the sets of ingredients that have a proportional relationship with the original recipe are: option A, C and D.

To check the proportional relationship of the ingredients with the recipe we must carry out the following procedure.

Option A.

First, we need to establish how many times 6 is in 12 because this recipe includes 6 parts oil and the original recipe includes 12 parts oil.

Once we identify this number, we must divide the amounts of the original recipe by 2 to identify if the other values are correct.

In accordance with the above, option 1 would be proportional to the main recipe. For the other options we must perform the same procedure:

In the case of case C. we identify that 24 is twice 12, so we would have to multiply each ingredient by 2 to check the proportional relationship

In the last case (option D), we identify that the proportion is 3/4 with respect to the original recipe, so we must carry out the same procedure keeping this proportion in mind.

Absolute advantage refers to the ability of a country or firm to produce a good or service at a lower cost than another country or firm. It is a concept in international trade and economic theory.

A country or firm has an absolute advantage in a good or service if it can produce that good or service more efficiently than another country or firm.

An individual has a comparative advantage in production if it produces at a lower opportunity cost when compared with other individuals.

The opportunity cost of Michael in the changing of oil = 10/ 8 = 1.25

Opportunity cost of Michael in changing tyres = 8 / 10 = 0.8

The opportunity cost of Martha in the changing of oil = 14 / 7 = 2

The opportunity cost of Martha in the changing of tyres = 7 / 14 = 0.5

Michael has an opportunity cost in changing of oil and Martha has an opportunity cost in changing of tyres.

Absolute advantage is when an individual produces more quantity of a good or service when compared to others.
