Fractions represent parts of a whole. This whole thing can be a region or a collection. The word break comes from the Latin word "fraction" which means "to divide". The earliest civilization to study fractions, the Egyptians, used fractions to solve mathematical problems such as the division of food, supplies, and the lack of bullion currency.

In ancient Rome, fractions were written to represent parts of a whole using only words. In India, fractions were originally written with the numbers (numerator and denominator) on top of each other, but without lines. Arabs were the only ones who added the dash used to separate the numerator and the denomination.

How do you dilate a triangle by 2 3?

Answers

A dilation is a transformation that changes the size of an object by a scale factor. To dilate a triangle by a scale factor of 2/3, you will need to follow these steps:

Identify the center of dilation: The center of dilation is a fixed point around which the dilation takes place. This point is usually denoted by the letter "C".

Identify the vertices of the triangle: The vertices of the triangle are the points that determine the shape and position of the triangle.

Calculate the new coordinates of the vertices: To dilate a triangle by a scale factor of 2/3, you need to multiply the coordinates of each vertex by the scale factor. For example, if the coordinates of a vertex are (x, y), the new coordinates will be (2/3x, 2/3y).

Plot the new coordinates: Once you have calculated the new coordinates of the vertices, you can plot them on the coordinate plane to create the dilated triangle.

Connect the new points to form the new triangle: Connect the new points with lines to form the new triangle

Note that the center of dilation C and the dilation factor are the same for all points on the triangle, also if the dilation factor is less than 1, the image is smaller than the original and if the dilation factor is greater than 1, the image is larger than the original.

A farmer decides to start selling his goats at a constant rate per month. After seven months, he has 280 goats left. After eleven months, he has 224 goats left.

Answers

If the farmer plotted a straight line graph of how many goats he had left over time, the slope of the line would be -14.

To find the slope of the line representing the number of goats the farmer has over time, we need to use the formula:

slope = (y2 - y1) / (x2 - x1)

Where y2 and y1 are the number of goats the farmer has at the end of two different months, and x2 and x1 are the number of months that have passed since he started selling the goats.

In this case:

y2 = 224 (goats left after 11 months)y1 = 280 (goats left after 7 months)x2 = 11 (months)x1 = 7 (months)

So the slope of the line is:

slope = (224 - 280) / (11 - 7)slope = -56 / 4 slope = -14

The slope of the line is -14, which means that the number of goats the farmer has decreases by 14 goats per month.

It's important to note that when the value of the slope is negative, it means that the line is going down; this means that the farmer is selling goats at a constant rate.

This question is incomplete and should be written as:

A farmer decides to start selling his goats at a constant rate per month. After seven months, he has 280 goats left. After eleven months, he has 224 goats left. If the farmer made a straight line graph representing how many goats he had left over time, what would be the slope of the line?

Answers

The value of 0.55 hectometers expressed in decimeters is 550 decimeters. The result is obtained by using the concept of unit ladder system.

How the unit ladder method works?

The common length units are kilometers to milimeter. The conversion can be described in a unit ladder system as follows.

km (kilometers)

  hm (hectometers)

     dam (decameters)

        m (meters)

           dm (decimeters)

              cm (centimeters)

                  mm (millimeters)

Every time the length unit goes down, it is multiplied by ten. Every time the length unit goes up, it is divided by ten.

We have 0.55 hectometers. Express that value in decimeters!

From hectometers to decimeters, it goes down 3 times. So,

0.55 hectometers = 0.55 × 10 × 10 × 10 decimeters

0.55 hectometers = 0.55 × 1000 decimeters

0.55 hectometers = 550 decimeters

Hence, 0.55 hectometers is equal to 550 decimeters.

It is also possible to simplify the powers of complex numbers using De Moivre's Theorem:

[tex](a + bi)^n = a^n + (na^{(n-1)})bi + (n(n-1)/2!)a^{(n-2)(bi)^2} + .... + (n(n-1)...21)(a*bi)^n[/tex]

Where [tex](a + bi)^n = r^n * (cos(n\theta) + i*sin(n\theta))[/tex]

Where r is the magnitude, θ is the argument, and n is an integer.

For example, if we raise i to the power of 3, we can use De Moivre's Theorem:

i³ = (cos(90) + isin(90))³ = cos(270) + isin(270) = -i

So, i³ = -i

When raising complex numbers to powers, the magnitude will be raised to the power of n while the argument will be multiplied by n.

i² = -1, so i³³ can be written as (i²)¹⁶ * i = (-1)¹⁶ * i = i

Area of circle equals Area of produced rectangle equals 1/2 π(2r) r.

Since r is the circle's radius and is equal to 22/7 or 3.14, the area of the circle is equal to πr².

What is circle ?

All points on a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant.

The following is a list of a circle's attributes:

A closed 2D form that isn't a polygon is a circle. It has one face that curves.If two circles have the same radius, they are said to be congruent.Equal chords are always located equally from the circle's center.The center of the circle is the perpendicular bisector of a chord.The line joining the points of two overlapping circles will be perpendicular to the line joining the points of the circles' centers.The tangents drawn at the diameter's endpoints are perpendicular to one another.

Look closely at the above illustration; if we divide the circle into smaller pieces and arrange them in a particular order, a parallelogram will result. The circle progressively becomes the shape of a rectangle as it is split into smaller and smaller segments. The likelihood that it will have the above-illustrated rectangle form increases with the number of parts it has.

A rectangle's area equals its length times its width.

The ratio of a circle's radius to a rectangle's width (r)

When we compare a rectangle's length to a circle's circumference, we can see that the length is equal to half the diameter of the circle.

Area of circle equals Area of produced rectangle equals 1/2 π(2r) r.

Step-by-step explanation:

3. Choose any two complex numbers z, and z2 and show that the following statements are true for
those numbers. Then prove that the statements are true for any z₁ = a + bi and z₂ = c + di.
a. Z₁ + Z₁ and Z₂ + Z₂ are both real numbers.
b. Z₁-Z₁ and 22-Z₂ are both pure imaginary numbers.
c. Z₁ + Z₂ = Z₁ + Z₂
d. Z₁ Z₂ = Z₁ Z2
4. For what complex number z does z=z? Justify your conclusion.

Answers

The following statements are true for all the numbers. The proof is shown as follows.

What is an imaginary number?

A real number is multiplied by an imaginary unit, I whose feature i2 = 1 defines it as an imaginary number. Bi is an imaginary number, while b2 is its square. For instance, the square of the fictitious integer 5i is 25. Zero is regarded as both real and fictitious by definition.

We know z₁ = a + bi and zbar= a-bi

z1+z1bar=2a that is purely real. Similarly with z2 +z2bar

z1-z1bar=-2bi that is purely imaginary. Similarly with z2-z2bar

Again

z1bar+z2bar= a-bi+c-di

z1+z2(whole bar)=a+c-(b+d)i

Hence Z₁ + Z₂ = Z₁ + Z₂

Similarly

z1bar.z2bar=z1.z2(whole bar)

Hence proved
