The answer is options a and b are equivalent and option c and d are equivalent.

The composition of transformations is a way to describe how multiple transformations can be applied to an object to create a new image. To find out what combinations of transformations would create the new image from the original, we can work backwards from the new image and apply the inverse of each transformation in reverse order.

The first transformation is a rotation of 270 degrees counter-clockwise about the origin. To undo this rotation, we need to perform a rotation of 90 degrees clockwise about the origin. The matrix for this transformation is:

[0 1]

[-1 0]

The second transformation is given by the matrix B [0 1 -1 0]. To undo this transformation, we need to apply its inverse, which is:

[-1 0 0 -1]

[0 1 -1 0]

To summarize, the combinations of transformations that would create the new image from the original are:

a. Rotate 90 degrees clockwise about the origin, then apply transformation B [0 1 -1 0].

b. Apply transformation B [0 1 -1 0], then rotate 90 degrees clockwise about the origin.

c. Rotate 270 degrees counter-clockwise about the origin, then apply the inverse of transformation B [-1 0 0 -1].

d. Apply the inverse of transformation B [-1 0 0 -1], then rotate 270 degrees counter-clockwise about the origin.

Therefore, options a and b are equivalent, since rotation and transformation are both associative operations. Similarly, options c and d are equivalent for the same reason.

The four vertices of the ellipse are (-5, 3), (1, 3), (-2, -1), and (-2, 7).

What is a graph?

In computer science and mathematics, a graph is a collection of vertices (also known as nodes or points) connected by edges (also known as links or lines). Graphs are often used to represent relationships between objects or to model complex systems.

The given equation represents an ellipse centered at (-2, 3) with horizontal axis length 6 and vertical axis length 8.

To find the coordinates of the vertices, we need to identify the endpoints of the major and minor axes. The center of the ellipse is (-2, 3), so the endpoints of the major axis are (-2-3, 3) and (-2+3, 3), which simplify to (-5, 3) and (1, 3), respectively. The endpoints of the minor axis are (-2, 3-4) and (-2, 3+4), which simplify to (-2, -1) and (-2, 7), respectively.

Therefore, the four vertices of the ellipse are (-5, 3), (1, 3), (-2, -1), and (-2, 7).

Step-by-step explanation:

Для решения задачи мы можем использовать свойства треугольников и окружностей.

Первое, что мы можем заметить, это что треугольник ABD является равносторонним, так как все его стороны имеют одинаковую длину 13. Это означает, что угол ABD также равен 60 градусам.

Также мы можем заметить, что точка O является центром окружности, вписанной в треугольник ABD, так как все ее стороны касаются окружности в точке D. Из свойств вписанных углов, мы знаем, что угол AOD равен половине угла ABD, то есть 30 градусам.

Далее, мы можем заметить, что треугольник AOC является равнобедренным, так как угол ACO равен углу OCA (они оба равны 75 - 30 = 45 градусов), а сторона AC имеет одинаковую длину с стороной AB.

Таким образом, мы можем найти длину стороны AC, используя теорему косинусов для треугольника AOC:

AC^2 = AO^2 + OC^2 - 2 * AO * OC * cos(45)

Заметим, что AO = DO, так как точка O является центром вписанной окружности, а DO является радиусом этой окружности. Из прямоугольного треугольника ADO мы можем выразить DO как DO = AD/2 = 6.5.

Также, мы можем выразить OC, используя равенство углов в треугольнике ACO (ACO и AOD являются вертикальными углами):

ACO = AOD = 30 градусов

Тогда, угол OCA равен 180 - 2 * 45 = 90 градусам, что означает, что треугольник OCA является прямоугольным, и мы можем использовать теорему Пифагора:

OC^2 + AC^2 = OA^2

OC^2 + AC^2 = DO^2

AC^2 = DO^2 - OC^2

Теперь мы можем подставить выражения для DO и OC, и получить:

AC^2 = 6.5^2 - (6.5/sqrt(2))^2

AC^2 = 42.25 - 22.5625

AC^2 = 19.6875

AC = sqrt(19.6875)

AC = 4.43 (с точностью до сотых)

Таким образом, длина стороны AC равна пр

The point of intersection of the lines, if The coordinates of the first line (0, 0) and (4, 3), and The coordinates of the second line (0, 4) and (3, 0), is (1.92, 1.44).

An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.

Given:

The coordinates of the first line (0, 0) and (4, 3),

The coordinates of the second line (0, 4) and (3, 0),

Write the equation of the line as shown below,

The equation of the first line,

y - 0 = 3 - 0 / 4 - 0 (x - 0)

y = 3/4 x

4y = 3x

4y - 3x = 0

The equation of the second line,

y - 0 = (0 - 4) / (3 - 0)  (x - 3)

y = -4 / 3  (x - 3)

3y = -4x + 12

3y + 4x = 12

Solve these equations,

x = 1.92 and y = 1.44

Step-by-step explanation:

Juliet will earn the same amount of money whether she chooses a monthly salary of ​$1900 from the company or a base salary of ​$1800 plus a ​5% commission on furniture sales if her sales amount to $2000.

To find the amount of sales for which the two salary choices are equal, we set the equation for the base salary plus commission equal to the equation for the flat monthly salary. The equation can be written as:

1800 + 0.05x = 1900

where x is the amount of furniture sales in dollars.

Simplifying and solving for x, we get:

0.05x = 100

x = 2000

If she sells less than $2000 of furniture, she will earn more with the flat monthly salary of $1900. If she sells more than $2000 of furniture, she will earn more with the base salary plus commission. This calculation provides an important decision-making tool for Juliet, as she can tailor her salary choice based on her expected sales for the month.

To graph this equation, start at the origin (0,0) since there is not y-intercept.

Because slope is characterized by rise/run ( i.e. how many units up or down depending on whether it is positive or negative and then however many units to the right.

Because the rise (up and down, numerator) is 1, we know that we will go up one unit.

The run (side to side, denominator) is 4, so we will go to the right 4 units.

Here are the steps in dividing the given decimal.

1. Convert the divisor 0.004 into a non-decimal value by multiplying it by 1000.

In the same way, multiply the dividend 0.86 by 1000 as well.

2. The division now becomes 860 divided by 4. Let's now divide the numbers using short division.

Hence, the quotient of 860 by 4 is 215.

Therefore, 0.86 divided by 0.004 is 215.

Answer:

215.

Step-by-step explanation:

Divide decimals by multiplying both numbers by a factor of 10 so the divisor no longer has a decimal value. Then, use long division to divide as normal. Place the decimal point in the quotient directly above the decimal point in the dividend. Multiply both by 100 to get rid of the decimal part in the divisor.

The solution of the expression is x=0 and it is the only solution that is an integer.

An expression in mathematics is a combination of numbers, variables, and mathematical operations that evaluates to a numerical value or an algebraic expression.

To do this, we need to pick a range of x values and substitute them into each equation to find the corresponding y values.

Next, we need to find the points of intersection between the two curves. These are the x values where the two curves cross each other and have the same y value. To find these points, we will set the two equations equal to each other and solve for x:

=> x=5x−x³

Expanding this equation, we get

=> 4x³+x=0.

Factoring this equation, we get

=> x(4x²+1)=0.

This gives us two solutions, x=0 and x=±i√(1/4), where i is the imaginary unit. Since x can only take on real values, x=0 is the only solution that is an integer.

To calculate the return on Ayanda's investment using Option 1, we can use the simple interest formula.

\(\boxed{\begin{minipage}{7 cm}\underline{Simple Interest Formula}\\\\$ I =Prt$\\\\where:\\\\ \phantom{ww}$\bullet$ $I =$ interest accrued \\ \phantom{ww}$\bullet$ $P =$ principal amount \\ \phantom{ww}$\bullet$ $r =$ interest rate (in decimal form) \\ \phantom{ww}$\bullet$ $t =$ time (in years) \\ \end{minipage}}\)

Given values:

Substitute the given values into the formula and solve for I:

\(I=200000 \cdot 0.12 \cdot 6\)

\(I=24000 \cdot 6\)

\(I=144000\)

Therefore, the return on Ayanda's investment using Option 1 is R144000.

\(\hrulefill\)

To calculate the return on Ayanda's investment using Option 2, we can use the compound interest formula.

\(\boxed{\begin{minipage}{7 cm}\underline{Annual Compound Interest Formula}\\\\$ I=P\left(1+r\right)^{t}-P$\\\\where:\\\\ \phantom{ww}$\bullet$ $I =$ interest accrued \\ \phantom{ww}$\bullet$ $P =$ principal amount \\ \phantom{ww}$\bullet$ $r =$ interest rate (in decimal form) \\ \phantom{ww}$\bullet$ $t =$ time (in years) \\ \end{minipage}}\)

Given values:

Substitute the given values into the formula and solve for I:

\(I=200000(1+0.095)^6-200000\)

\(I=200000(1.095)^6-200000\)

\(I=200000(1.72379142...)-200000\)

\(I=344758.28426...-200000\)

\(I=144758.28426...\)

\(I=144758.28\)

Therefore, the return on Ayanda's investment using Option 2 is R144758.28.

\(\hrulefill\)

Comparing the returns from both options, we find that Option 1 offers a return of R144000, while Option 2 offers a return of R144758.28. As R144758.28 > R144000, then Option 2 will render the most money for Ayanda's investment.
