As a result, there is just one transformation from shape A to shape B: dilate A by 1/2, followed by a 180 degree rotation.

A drastic change in shape or appearance is called a transformation. An crucial occasion, such as receiving your driver's licence, enrolling in college, or getting married, might change the course of your life. Extreme, dramatic change is what we refer to as transformation.

When we move a figure in any direction, we say that we are translating. Flipping a figure over a line is what is meant by reflection. Rotation is the process of rotating a figure around a point by a specific amount. When we dilate a figure, it is enlarged or shrunk.

By multiplying the original shape by a scale factor, we can change the size of the shape and make it bigger or smaller. This type of modification is called an expansion.

A shape can be transformed by shifting its location and size.

Shape A can only be transformed into shape B by rotating 180 degrees and enlarging it by half.

Based on the figure, we can:

Shape A's side lengths are twice as long as Shape B's side lengths.

After dilatation, shape A can be rotated 180 degrees to imprint onto shape B.

The range of dilatation from shape A to shape B is thus:

Scale = 1/2

As a result, there is just one transformation from shape A to shape B: dilate A by 1/2, followed by a 180 degree rotation.

Therefore, if the borrower had paid the loan just at the end of the second year, he would have owed R 167250. The additional interest due would be R 167250 - 150000 = R 17250.

a) To calculate the amount of money that the person would have to pay at the end of the second year to clear his debt, you can use the formula for compound interest:l,

A = P(1 + r/n)^(nt)

Where A is the final amount, P is the initial principal, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.

In this case, the person took a loan of R 150000 for 2 years at an annual interest rate of 10%. He paid R 85000 at the end of the first year. So, the new principal at the beginning of the second year is P = 150000 - 85000 = 65000.

So, A = P(1 + r/n)^(nt)

A = 65000(1 + 0.1)^2

A = 65000*1.1^2

A = 73,650

So, the person should have to pay R 73650 at the end of the second year to clear his debt.

b) If the person had paid the loan only at the end of the second year, the interest would have been calculated on the original principal of R 150000 for 2 years. So,

A = P(1 + r/n)^(nt)

A = 150000(1 + 0.1)^2

A = 150000*1.1^2

A = 167250

So, the person would have had to pay R 167250 if he had paid the loan only at the end of the second year. Therefore, he would have to pay more interest of R 167250 - 150000 = R 17250.

A 360-degree angle can be visualized as a full rotation or circle, and it is often used to measure angles in a circular context.

A 360-degree angle is a complete rotation and is equivalent to one full circle. It is often represented as a circle with a line that goes from the center of the circle to the outer edge, marking the angle.

When looking at a 360-degree angle, it can be divided into four quadrants: the top right, top left, bottom left, and bottom right. Each quadrant is 90 degrees or one-fourth of the total angle. This division is useful when analyzing or measuring angles in different sections of a circle.

In terms of visual representation, imagine a clock face with the numbers 1-12. The clock face is a 360-degree angle, with each number representing a 30 degree increment. The hour hand of the clock would rotate around the face, completing a full rotation and reaching the starting point at the 12 o'clock position, completing a 360 degree angle.

In other words, a 360 degree angle can be visualized as a full rotation or circle, and it is often used to measure angles in a circular context. It can also be divided into smaller sections for analysis or measurement purposes.

Answer:The American colonies declared independence from British rule in 1776 because they were seeking to establish themselves as a sovereign nation, separate from British control and governance.

The colonies had grown increasingly discontent with British rule and policies, particularly those related to taxation and trade. The colonists felt that they were not being fairly represented in British government and that the laws and taxes imposed on them by Britain were unjust and burdensome.

In 1765, the British Parliament passed the Stamp Act, which placed a tax on printed materials such as newspapers, legal documents, and books. The colonists saw this as a violation of their rights as British citizens, as they had no representation in Parliament and felt that they were being taxed without their consent. This led to widespread protests and resistance to the tax, known as the Stamp Act riots.

In 1773, the British government passed the Tea Act, which granted a monopoly on the sale of tea to the British East India Company and imposed taxes on tea imported to the colonies. This led to the famous Boston Tea Party, in which colonists dumped 342 chests of tea into the Boston Harbor as a protest against the tax.

These and other events, such as the Quartering Acts and the Intolerable Acts, which were designed to punish the colonies for their resistance, further fueled the colonists' anger and resentment towards British rule.

In 1774, the First Continental Congress was held, in which representatives from the colonies met to discuss a unified response to British policies. The Congress adopted a Declaration of Rights and Grievances, in which they demanded that their rights as British citizens be respected and that they be given fair representation in Parliament.

In 1775, the American Revolutionary War broke out between the colonies and Great Britain. On July 4, 1776, the Second Continental Congress adopted the Declaration of Independence, which stated that the colonies were no longer subject to British rule

Step-by-step explanation:

Answer: The colonists joined together to fight Britain and gain independence.

Step-by-step explanation: Many colonists were angry because no one represented their needs in the British government. Colonists believed they did not have self-government. The British forced colonists to allow British soldiers to sleep and eat in their homes.

To calculate the volume of a triangular prism, you need to know the base area and the height. In this case, the base area is given as 4 cm^2, and the areas of the sides are given as 9 cm^2, 10 cm^2 and 17 cm^2.

To find the volume of the prism, you can use the formula:

Volume = Base Area x Height

Since we don't know the height of the prism, we can use the area of the sides to find the height.

To find the height, we need to use the formula of area of the triangle.

Area = (1/2) x b x h

let's use the area of one side (for example 9cm^2)

9cm^2 = (1/2) x b x h

we can divide both sides by (1/2) x b

h = (2 * 9cm^2) / b

Now we have the height of the triangular prism, so we can use that to find the volume.

so the volume of the triangular prism = Base Area x Height = 4cm^2 x ( (2 * 9cm^2) / b) = 72/b cm^3

As we don't know the value of b, we can't find the exact volume of the prism.

Answer:

12 cm³

Step-by-step explanation:

Conditions:
a * h = 9 cm
b * h = 10 cm
c * h = 17 cm
S = 4 cm²

To calculate the area on three sides, we use the Heron formula:

[tex]S = \sqrt{p * (p-a) *(p-b)*(p-c)[/tex]
where "p" is the semi-perimeter:
[tex]p = \frac{(a+b+c)}{2}[/tex]

Let's express the sides in terms of the height:
a = 9/h
b = 10/h
c = 17/h

Then the semiperimeter will be:
p = (9/h+10/h+17/h) : 2 = 36/h : 2 = 18/h

Substituting the values into the Heron formula:
4 = √(18/h * (18/h - 9/h) * (18/h - 10/h) * (18/h - 17/h))
4² = 18/h * (18/h - 9/h) * (18/h - 10/h) * (18/h - 17/h)
16 = 18/h * 9/h * 8/h * 1/h
16 = 1296 / h^4
h^4 = 1296 / 16 = 81
h = 3 cm

Now we can calculate the volume of the pyramid:
V = S * h = 4 cm² * 3 cm = 12 cm³

The maximum value of log(x)/ x is 1/e.

The function given is f(x) = log(x)/ x

As base is not mentioned assuming that the base is e.

To find maximum value, let us find the critical point of this function equating its first derivative to 0.

d/dx (f(x) = log(x)/ x) = ( 1 - log(x))/ x²

So d/dx (f(x)) = 0 when 1 - log(x) = 0

That is log(x) = 1

So x = e

f''(x) = (2log(x) - 3)/ x³

f''(e) = (2log(e) - 3)/ e³ = -1/e³ < 0

The slope-intercept form is

y = mx + b, where m is the slope and b is the y-intercept.

y = mx + b

Find the values of m and b, using the slope-intercept equation.

Now, using this information,

y = −4x − 6

y = mx + c

m → slope

the slope is −4 and

y−intercept would be (0,−6).

Thus, the y-intercept is (0, -6).
