The formula to calculate the measure of each individual exterior angle in any polygon is: Exterior angle measure = 360°/n.

To find the measure of each individual exterior angle in any polygon, first, you must understand the Polygon Exterior Angle-Sum Theorem, which states that the exterior angles of any polygon add up to 360 degrees.

With this information, the formula for the measure of an individual exterior angle is simple: Exterior angle measure = 360°/n, where n is the number of sides in the polygon.

By dividing the total sum of the exterior angles (360°) by the number of sides (n) in the polygon, you can determine the measure of each individual exterior angle.

The triangle third side may be 6 or 9 metres long, or it may be between 9 and 15 metres long.

Depending on the lengths of the other two sides, the triangle's third side can have a variety of lengths. The third side's length could range from 9 to 15 metres if the first two sides are 6 and 9 metres, respectively. The reason for this is that the length of any two sides of a triangle must always be greater than the length of the third side; in this instance, the sum of the two sides is 15 metres, or 6 and 9 metres. As a result, the triangle's third side must be either less than or equal to 15 metres. A triangle can also have two equal sides, so the third side could also be equal to 6 or 9 metres. In conclusion, the third side of the triangle may be anywhere between 9 and 15 metres long, or it could be 6 or 9 metres long.

x = 3

y = -1

Step-by-step explanation:

5x + 3y = 12

x - 4y= 7

Times the second equation by -5

5x + 3y = 12

-5x + 20y = -35

23y = -23

y = -1

Now put -1 back in for y and solve for x

x - 4(-1) = 7

x + 4 = 7

x = 3

Let's check

3 - 4(-1)= 7

3 + 4 = 7

7 = 7

So, x = 3 and y = -1 is the correct answer.

By several orders of magnitude, the role that money plays in the rate of urbanization and various economic activities is significant.

The proportion of people who live in towns and cities growing is known as urbanization. People relocate to urban areas from rural (countryside) areas, which causes urbanization (towns and cities). This typically happens when a nation is still growing.

Urban areas can expand due to a rise in the population or because people move there. Urbanization causes habitat loss, deforestation, and freshwater extraction from the environment, which can reduce natural things and change species ranges and interactions.

Find the complete question below.

Height of a cuboid is three-fourths of its length,breadth is 4 cm and total surface area is 608.

the length of the cuboid is 24 cm and its height is 18 cm.

Let us denote the length of the cuboid as "l" and the height of the cuboid as "h".

Based on the facts provided, we may conclude:

h = (3/4)l

Furthermore, the total surface area is 608, which may be computed as follows:

608 = 2(lb + bh + lh)

Extending the formula and changing the value of h:

608 = 2(lb + bh + l(3/4)l)

2(lb + 4h + (3/4)l^2) = 608

Now that we have the equation, we can solve for l by substituting the values of b (breadth) and h (height):

2(4l + 4h + (3/4)l^2) = 608

8l + 8h + (3/2)l^2 = 304

(3/2)l^2 + 8l + 8h = 304

We can now solve for l using the quadratic formula:

l = (-8 ± √(8^2 - 4 * (3/2) * (304 - 8h))) / (2 * (3/2))

Because h = (3/4)l, we may simplify by substituting this formula for h:

l = (-8 ± √(8^2 - 4 * (3/2) * (304 - 3l))) / (2 * (3/2))

Expanding the square root:

l = (-8 ± √(64 + 12l)) / 3

When we solve for l, we get:

l = 24

Finally, for h, substitute the value of l into the equation:

h = (3/4) * 24 = 18

Answer:

Step-by-step explanation:

To find a sinusoidal function that matches the given graph, we need to find the amplitude (A), period (T), phase shift (h), and vertical shift (k) of the function.

Since the graph goes through the points (-9,0) and (5,0), we know that the maximum value of the function is located at the average of the x-values, which is -2, and that the minimum value of the function is located at the average of the x-values, which is (9+5)/2 = 7. The amplitude of the function can be found by taking half the difference of the maximum and minimum y-values, which is 0 - (-2)/2 = 1.

The period of the function can be found by taking the difference of the x-values of two consecutive maxima or minima, which is 5-(-9) = 14.

The phase shift can be found by noting the horizontal shift of the graph from its standard form, which is usually given by the equation y = A sin(x). In this case, the graph is shifted 2 units to the right, so the phase shift is 2.

The vertical shift can be found by noting the location of the midline of the graph, which is half way between the maximum and minimum y-values. In this case, the midline is at y = -1.

Putting all these values together, we can write a sinusoidal function that matches the given graph as:

f(x) = 1 sin(x + 2π/14) - 1

This function has amplitude 1, period 14, phase shift 2π/14 to the right, and a vertical shift of -1 down.

The perimeter of the floor in the scale drawing is 42 inches.

To find the scale factor, we can use the length of the room in the original and the scaled drawing:

scale factor = length in scale drawing / length in original = 10 inches / 30 feet

Since 1 foot = 12 inches, we can convert the length of the room to inches:

30 feet * 12 = 360 inches

So, the scale factor is 10 inches / 360 inches = 1/36.

To find the length of the room in the scaled drawing, we can use the scale factor:

length in scale drawing = scale factor * length in original = (1/36) * 360 inches = 10 inches

And the width in the scaled drawing would be:

width in scale drawing = scale factor * width in original = (1/36) * 33 feet * 12 inches/foot = (1/36) * 396 inches = 11 inches

Finally, to find the perimeter of the room in the scaled drawing, we add up the lengths of all four sides:

perimeter = 2 * (length in scale drawing) + 2 * (width in scale drawing) = 2 * 10 inches + 2 * 11 inches = 20 inches + 22 inches = 42 inches.

Option C is correct : y = ±3x + 8, represents a function because it satisfies the vertical line test.

"y = ±3x + 8" represents a function. A function is a mathematical relationship between a set of inputs (in this case, x) and a set of outputs (in this case, y). In this equation, for each value of x there is exactly one corresponding value of y, which means that it represents a function.

"y = ±2x + 3" is not a function because for each value x, there are two possible values y (one positive and one negative). This is not the definition of a function, as a function must have exactly one output value for each input value.

Options B, D, and E do not represent functions because they do not have an equal sign between the x and y variables, which is the defining characteristic of a mathematical function.

Answer: Let's call the length of one side of the equilateral triangle x.

(x/2)^2 + (√3/2)^2 = (x/2)^2 + 3/4 = x^2/4 + 3/4 = x^2/4 + 3/4 = x^2/4

So:

x^2 = 4 * (x^2/4 + 3/4) = 4x^2/4 + 4 * 3/4 = 4x^2/4 + 3
