A hexagon, also known as a sexagon, is a six-sided polygon that forms the shape of a cube in geometry. Any basic hexagon has a total internal angle of 720°.

In a regular hexagon, all sides are equal

Which means:

AB= BC

5p + q -5p = 6p-5p

q = p

So, every side of the hexagon is p = q

Which means that AB = BC = CD = DE = EF = FA = p =q

Recall that at the center, each side forms an angle

There are six sides in a hexagon.

Total angle = 360°

6x= 360°

x= 60°.

By the symmetry of regular hexagon, OA = OB

<OAB = <OBA

<AOB = x = 60°

Sum of all angles in a triangle is 180°

We add the values

<OAB = 60°.

<OAB is an equilateral triangle, thus every side is equal

Hence,

a. OA = Q = Q

b. OB = P =Q

c. EB = 2P =2Q.

From the figure, <BOE= 180° which makes it a straight line.

The coordinates of the intercepts of the depreciation equation are (9, 0) and (0, 22,995).

The x intercept is the x coordinate of a point where the line touches the X axis.

The y intercept is the y coordinate of a point where the line touches the Y axis.

Here, there are two variables.

The independent variable x is the number of years.

The dependent variable y is the value of the car.

x intercept is the year when the value of the car is 0.

Given that, model of a car loses all of it's marketable value after 9 years.

x intercept = 9

y intercept is the value of the car in the 0th year.

Initial value of the car = $22,995

y intercept = 22,995

Hence the intercepts are (9, 0) and (0, 22,995).

Answer:

6,072

Step-by-step explanation:

5,600 - 4,420 = 1,180

They gained 1,180 people over 5 years.  Now we need to find how many people they gain every year (roughly).

Since it's 5 years, we are going to divide.

1,180 / 5 = 236

They gained 236 people over 1 year.  Since 1998 is two years is before 2000, we're going to multiply 236 by 2.

236 x 2 = 472

Now we add this to the 1998 population.

5,600 + 472 - 6,072

The population in the year 2,000 is 6,072

In multiple regression, we have 4 assumptions listed and explained below. They are valid.

Following are assumptions for multiple regression model:

1. Linear connection: Each predictor variable and the responder variable have a linear relationship.

Making a scatter plot of each predictor variable and the response variable is the simplest technique to check if this premise is true.

2. Lack of Multicollinearity: There is no significant correlation between any of the predictor variables.

Calculating the VIF value for each predictor variable is the quickest approach to see if this premise is true.

3. Independence: Each observation has its own validity.

The Durbin-Watson test, a formal statistical test that informs us whether or not the residuals (and consequently the observations) exhibit autocorrelation, is the easiest approach to find out if this assumption is true.

4. Homoscedasticity: At every point in the linear model, the residuals' variance is constant.

The simplest technique to check if this premise is true is to plot the standardized residuals against the expected values.

The values for g and f for the length of sides of the trapezium are 8 and 6 respectively.

Given the area of trapezium = 60 cm², then:

1/2 × (g + 4g) × f = 60 cm²

by simplification

f(g + 2) = 60 cm²...(1)

for the area of ABCD = 48 cm², then:

f × g = 48 cm²

f = 48/g...(2)

put 48/g for f in equation (1) to get g;

48/g(g + 2) = 60

60g = 48g + 96 {cross multiplication}

60g - 48g = 96 {collect like terms}

12g = 96

g = 96/11 {divide through by 11}

g = 8

put 8 for g in equation (2) to get f;

b)  Mark these x,y values on the graph to identify the curve that matches all points.  That is curve B.

Answer:

(-1,-3)

Step-by-step explanation:

See the attached worksheet.  First step is to apply the transformation.  Modifiy the x and y points as per the instructions.  The transformed triangle is shown in blue and the coordinates are listed.  As the directions indicate, it is slipped down by 2 and to the left by 3 (y-2 and x-3).

Next, convert the x values so that they are reflected across the y axis.  The table shows that all x values are the negative of their original values.  The reflected triangle is shown in red.

The new point Z is (-1,-3).

The system of equations is:

y = 19 + 4*x

y = 15 + 6x

And the solution is x = 2 and y = 27.

We know that red is using a 19-kilogram bar, increasing the amount of weight he lifts by 4 kilograms on each set. Then after x sets he will be lifting:

y = 19 + 4*x

kilograms.

And his partner, meanwhile, started out using a 15-kilogram bar and is upping the weight by adding 6 kilograms on every set. Here we can write:

y = 15 + 6x

Then we need to solve the system of equations at:

y = 19 + 4*x

y = 15 + 6x

Using substitution, wecan write:

19 + 4x = 15 + 6x

19 - 15 = 6x - 4x

4 = 2x

4/2 = x

2 = x

They will lift the same weight after 2 sets, and the weight is:

y = 19 + 4*2

y = 19 + 8 = 27

They will be lifting 27 kilograms.

The required standard form of the quadratic function that has the indicated vertex and whose graph passes through the given point is y = -2x² + 12x - 17.

The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.

To find the quadratic function that has the vertex (3, 1) and passes through the point (5, -7), we can use the vertex form of the quadratic function: y = a(x - h)² + k, where (h, k) is the vertex.

First, we substitute the vertex (5, -7) into the vertex form to find a:

y = a(x - 3)² + 1

-7 = a[2]² + 1
a = -2

Since a = -2, the standard form of the quadratic function is:

y = -2x² + bx + c

Substitute the point (5, -7) into the standard form y = -2x² + bx + c to find b and c:

-7 = -2x² + b(5) + c

-7 = -50 + 5b + c

43 = 5b + c - - - - -(1)

Substitute the point (3, 1) into the standard form y = -2x² + bx + c to find b and c:

1 = -18 + b(3) + c

19 =3b + c - - - - -(2)

Solving equations 1 and 2 we get
43 - 19 = 2b
b = 12 and c = -17

Put a,b and c in the standard equation,
y = ax² + bx + c
y = -2x² + 12x - 17

To find three additional polar representations of the point (2, 3π/4), we can add or subtract 2πk to the angle, where k is an integer. Using this method, we get:

   (2, -5π/4) - subtract 2π

   (2, 11π/4) - add 2π

   (2, -3π/4) - subtract 2π

To find the smallest and largest values of the angle, we need to consider the interval −2π < θ < 2π. The given angle of 3π/4 lies in the second quadrant. Adding or subtracting 2π to this angle will give us angles in the third and fourth quadrants. Therefore, the smallest value of the angle is −3π/4, and the largest value is 5π/4. Thus, the polar representations are:

   (2, 3π/4)

   (2, -5π/4)

   (2, 11π/4)

   (2, -3π/4)

   (2, 5π/4)

The provided parallelogram has angles of 45 degrees and 45 degrees, as well as 48 degrees and 48 degrees.

A parallelogram is a basic quadrilateral with two pairs of parallel sides in Euclidean geometry. A parallelogram's opposing or facing sides are of equal length, and its opposite angles are of equal measure. A parallelogram is a quadrilateral with opposing sides that are parallel and equal. It has equal interior opposite angles. In addition, the angles on the same side of the transversal add up to 180 degrees or are additive to each other.

Here,

A parallelogram has two pairs of opposite angles that are equal.

Since one angle of the parallelogram is 48 degrees, its opposite angle must also be 48 degrees.

The other two angles must add up to 90 degrees (since they form a right angle), so they must each be equal to 180 - 90 = 90 degrees / 2 = 45 degrees.

So, the other angles of the parallelogram are 45 degrees and 45 degrees.

The angles of given parallelogram are 45 degrees and 45 degrees as well as 48 degrees and 48 degrees.
