Please Help !! Write A Sequence Of Rigid Transformations That Could Take One Triangle To Another

Answers

Answer 1

The required scale factor of the dilation, between the triangles, is 3/4.2.

What is the transformation of geometry over the coordinate plane?

Transform the shapes on a coordinate plane by rotating, reflecting, or translating them. Felix Klein introduced transformational geometry, a fresh viewpoint on geometry, in the 19th century.

Here,
To determine, a sequence of rigid transformations that could take one triangle to another.

Since as we can see, the triangles have certain dilation, translation, and reflection. As for the data given, we can only calculate the dilation factor or scale factor only.

So,
Scale factor = Length of the one side of 1st triangle/length of 2nd triangle.

Scale factor = 6/8.4
Scale factor = 3/4.2

Thus, the required scale factor of the dilation, between the triangles is 3/4.2.

Correct tion for the circle with the following properties. Center (4,8), passes through (-10,-5)

Answers

The equation of a circle with center at (4, 8) and passing through (-10, -5) is [tex](x-4)^2 + (y-8)^2 = (6)^2.[/tex]


To find this equation, we need to use the distance formula: [tex]d = sqrt((x2-x1)^2 + (y2-y1)^2).[/tex]

We can substitute in the coordinates of the center of the circle and the point it passes through:

[tex]d = sqrt((-10-4)^2 + (-5-8)^2)[/tex]
[tex]d = sqrt( (6)^2 + (13)^2 )[/tex]

d = sqrt(36 + 169)

d = sqrt(205)

d = 14.2

Now, we have the radius of the circle. We can use this to form the equation of the circle:

[tex](x-4)^2 + (y-8)^2 = (14.2)^2[/tex]

[tex](x-4)^2 + (y-8)^2 = (6)^2[/tex]

Answers

The coordinates of B' after the translation represented by (x - 4, y - 3) is (1, -2). See other solutions below

The coordinates of B' after the translation

B is located at the point (5, 1) in the figure.

If we translate the point by (x - 4, y - 3), the new location of B, denoted by B', can be found by subtracting 4 from the x-coordinate and 3 from the y-coordinate.

Therefore, B' is located at (1, -2).

The isometry transformation

The given information provides us with a set of matching points, which are:

Preimage = (2, 1)

Image = (-1, 2)

These points can be represented by the equation:

(x, y) = (-y, x)

This equation indicates that the points have undergone a (d) clockwise rotation of 270 degrees.

The statements of the dilation

Here, the smaller shape is created by scaling down a larger shape, the transformation is a dilation that results in a reduction.

The scale factor for this transformation could be either 1/2 or 1/4.

The glide transformaton

Given the points P = (3, -2) and S = (4, -5), we apply two transformations.

The first transformation (x - 2, y) is defined as shifting the x-coordinate of each point left by 2 units, while keeping the y-coordinate the same.

This results in new points P' = (1, -2) and S' = (2, -5).

The second transformation involves reflecting the new points across the x-axis, which changes the sign of their y-coordinates.

The resulting points are P'' = (1, 2) and S'' = (2, 5).

The new ordered pair of point A

In this context, we are given the coordinates of point A as (-2, -5).

This implies that if we scale down the original coordinates by a factor of 1/2, we get the new coordinates of point A, which become (-1, -2.5).

Therefore, the coordinates of point A' are (-1, -2.5).

4^2 =2 x (----- + 3) complete this calculation

Answers

Answer:

4^2 = 2 x (5 + 3) = 2 x 8 = 16

Step by step solved:

Starting with 4^2 = 2 x (----- + 3), we can work backwards to solve for the missing value:

4^2 = 2 x (----- + 3)

4^2 = 2 x (x + 3) (let x represent the missing value)

4^2 = 2x + 6

16 = 2x + 6 (evaluate 4^2 as 16)

10 = 2x

5 = x

Do segments with lengths 11, 12, and 20 form a triangle? If so, classify the triangle as acute, right, or obtuse?

Answers

Answer:

Yes, the segments with lengths 11, 12, and 20 can form a triangle.

To check this, we can use the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

In this case, we can check that:

11 + 12 > 20

11 + 20 > 12

12 + 20 > 11

Since all three inequalities are satisfied, the segments can form a triangle.

To classify the triangle, we can use the law of cosines, which relates the lengths of the sides of a triangle to the cosine of one of its angles. Specifically, for a triangle with sides a, b, and c and angle A opposite side a, we have:

c^2 = a^2 + b^2 - 2ab cos(A)

Using this formula, we can find the cosine of each angle and determine if the triangle is acute, right, or obtuse based on the values obtained.

For the given triangle, we have:

a = 11, b = 12, c = 20

cos(A) = (b^2 + c^2 - a^2) / (2bc) = (12^2 + 20^2 - 11^2) / (2 * 12 * 20) ≈ 0.714

Since cos(A) is positive and less than 1, the angle A is acute. Similarly, we can find the cosines of the other angles:

cos(B) = (c^2 + a^2 - b^2) / (2ca) ≈ 0.943

cos(C) = (a^2 + b^2 - c^2) / (2ab) ≈ -0.519

Since cos(B) and cos(C) are both positive and less than 1, angles B and C are also acute.

Therefore, the given triangle is acute.

The y-intercept of line t is equal to -1.

A table representing points on line s is shown below.

An equation that could represent line s is: IV. y = 1/3x +4​.

How to calculate the slope of a line?

In Mathematics, the slope of any straight line can be determined by using this mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope, m = (0 - (-1))/(3 - 0)

Slope, m = 1/3

Based on the graph, the y-intercept of t is at point (0, -1)

Additionally, a table representing points on line s is given by;

Work out the surface area of this solid
cylinder.
Give your answer rounded to 3 SF.
28mm
30mm
The diagram is not drawn to scale.

Answers

Answer: The surface area of a cylinder is given by the formula:

S = 2πr^2 + 2πrh

where r is the radius of the base, h is the height of the cylinder, and π is the mathematical constant pi.

In this case, the radius is 28 mm and the height is 30 mm.

Substituting these values into the formula, we get:

S = 2π(28)^2 + 2π(28)(30)

Simplifying the equation:

S = 2π(28)(28 + 30)

S = 2π(28)(58)

S = 32176π

Using a calculator, we can approximate the value of S to 3 significant figures:

S ≈ 101285.744 mm^2

Therefore, the surface area of the cylinder is approximately 101286 mm^2 (rounded to 3 significant figures).

A retailer sells model solar systems for $72 that were acquired at a cost of $24. What is the mark-up percentage?

Answers

Therefore, the mark-up percentage for the model solar system is 200%. This means that the selling price is twice the cost price.

I have to figure out a percentage.

We must divide the value by the entire value to find the percentage, then increase the resulting number by 100.

The mark-up percentage is the percentage by which the selling price exceeds the cost price.

In this case, the cost price of the model solar system is $24 and the selling price is $72. The mark-up amount is the difference between the selling price and the cost price, which is:

$72 - $24 = $48

To find the mark-up percentage, we divide the mark-up amount by the cost price and multiply by 100:

Mark-up percentage = (Mark-up amount / Cost price) x 100%

Mark-up percentage = ($48 / $24) x 100%

Mark-up percentage = 200%

Therefore, the mark-up percentage for the model solar system is 200%. This means that the selling price is twice the cost price.

The area of a classroom is 20 square meters. If the length is increased by 3 meters and the width is increased by 1 meter, the classroom will double in area. Determine the dimension of the new classroom.

Answers

The dimension of the new classroom is 8 meters of length and 5 meters of width.

What is Area?

Area of a two dimensional shape is the total region which is bounded by the object's shape.

Given that,

Area of the classroom = 20 square meters

Let x be the length and y be the width of the classroom.

Area of a rectangular classroom = Length × Width.

So, we get an equation,

xy = 20

x = 20/y [Equation 1]

If length is increased by 3 meters and the width is increased by 1 meter, the classroom will double in area.

(x + 3) (y + 1) = 20 × 2

(x + 3) (y + 1) = 40  [Equation 2]

Substitute [Equation 1] in [Equation 2]

((20/y) + 3) (y + 1) = 40  

Multiplying,

20 + 3y + (20/y) + 3 = 40

3y + (20/y) = 40 - 23

3y + (20/y) = 17

Multiplying throughout by y,

3y² + 20 = 17y

3y² - 17y + 20 = 0

3y² - 12y - 5y + 20 = 0

3y (y - 4) - 5 (y - 4) = 0

(3y - 5) (y - 4) = 0

3y - 5 = 0 or y - 4 = 0

y = 5/3 or y = 4

Let y = 4, then x = 20/4 = 5

Dimension of the new classroom is (x+3) = 8 meters and (y+1) = 5 meters

Hence the dimension of the new classroom is 8 meters and 5 meters.

\[ \left|\begin{array}{ccc} a & b & c \\ d & e & f \\ g & h & i \end{array}\right| = a(ei - fh) - b(di - fg) + c(dh - eg) \]

In this case, we can substitute the values from the given matrix into the formula:
\[ \left|\begin{array}{ccc} d+b & d & d \\ d & d+b & d \\ d & d & d+b \end{array}\right| = (d+b)((d+b)(d+b) - d^2) - d(d(d+b) - d^2) + d(d^2 - d(d+b)) \]
Simplifying the expression gives:

\[ = (d+b)(2bd + b^2) - d(bd) + d(-bd) \]
\[ = 2bd^2 + 2b^2d + b^3 - bd^2 - bd^2 \]

A population consists of five members 2,3,6,8,1). consider all possible samples of size two which can be doamn with replacement from this positioning population.  The mean is  4 and standard deviation of the population is 1.67. The mean and standard error of sample mean (x) from the sampling distribution of x is 4 and 1.18 respectively

i) The mean and standard deviation of the population:

Mean = (2+3+6+8+1)/5 = 20/5 = 4

Standard deviation = √[(2-4)²+(3-4)²+(6-4)²+(8-4)²+(1-4)²]/5 = √14/5 = 1.67


ii) The mean and standard error of sample mean (x) from the sampling distribution of x:

Mean of sample mean = Mean of population = 4

Standard error of sample mean = Standard deviation of population/√n = 1.67/√2 = 1.18


The mean of a population is calculated by adding up all the values and dividing by the number of values in the population. The standard deviation of a population is calculated by finding the difference between each value and the mean, squaring those differences, adding them up, and then dividing by the number of values in the population.

The mean of the sample mean is the same as the mean of the population, and the standard error of the sample mean is the standard deviation of the population divided by the square root of the sample size.

What is isosceles trapezoid?

An isosceles trapezoid can be defined as a trapezoid whose non-parallel sides and base angles have the same measure. That is, if the two opposite sides (bases) of a trapezoid are parallel and the two non-parallel sides are of equal length, it is an isosceles trapezoid.

Given,

Isosceles trapezoid QRST

m∠S = 82°

Base angles are equal in Isosceles trapezoid

m∠R = m∠S

m∠R = 82°

and

m∠Q = m∠T

Sum of all interior angles of a quadrilateral is 360°

m∠Q + m∠T + m∠R + m∠S = 360°

m∠Q + m∠Q + 82° + 82° = 360°

2 m∠Q = 360° - 164°

2 m∠Q = 196°

m∠Q = 98°

m∠T = 98°

Answer: The employee payed $36 for the item.

Step-by-step explanation:

Take $40 and since the employee gets a 10% discount

do $40 times 10% and you get 4

so take 4 away from the $40

40-4=36

Fill in the missing value. 4:9 = ? : 36

Answers

i think it may be 16:36

explanation: if the 9 was multiplied by 4 which 9x4 is 36 it means that the 4 for the 4:9 will probably end up 16 hence 4x4 is 16 making the answer probably 16:36 to my own understanding

The answer is calculated by elementary row operations

To factor the given complex matrices into unitary times upper triangular, you will need to use elementary row operations. Specifically, you can use scaling, addition, subtraction, and multiplication of rows.

(i) i 1:

Row 1: Scale by i

Result: i2 1 = -1 1

(ii) 1+i 2-1:

Row 1: Subtract Row 2

Result: 1 0 -1

Row 2: Scale by i

Result: i 1 -i

(iii) i 1 0 , -1 2i 1-i -1 1 i 1

Row 1: Subtract i times Row 2

Result: 0 1 0 , -1 2i 0 -i -1 0 i

Row 2: Scale by i

Result: 0 1 0 , i 0 -1 -i -1 0 1

Row 3: Subtract Row 1

Result: 0 0 0 , i 0 -1 -i -1 0 1

(iv) 1 1 -i

Row 1: Subtract Row 2

Result: 1 0 -i

Row 2: Scale by i

Result: i 0 1+i

Aisha is going to invest in an account paying an interest rate of 2.7% compounded
quarterly. How much would Aisha need to invest, to the nearest ten dollars, for the
value of the account to reach $6,800 in 16 years?

Answers

[tex]~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\dotfill & \$ 6800\\ P=\textit{original amount deposited}\\ r=rate\to 2.7\%\to \frac{2.7}{100}\dotfill &0.027\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{quarterly, thus four} \end{array}\dotfill &4\\ t=years\dotfill &16 \end{cases}[/tex]

[tex]6800 = P\left(1+\frac{0.027}{4}\right)^{4\cdot 16} \implies 6800=P(1.00675)^{64} \\\\\\ \cfrac{6800}{(1.00675)^{64}}=P\implies 4420\approx P[/tex]

Suppose that a distribution is normal, with mean =10 and standard deviation =3. Two samples a and b, each of length N, are independently drawn from this distribution. For which of the following operations on a and b will the resulting distribution also be normal?
If the distribution is normal, state this and provide exact mathematical expressions (integer, fraction, radical, etc.) for the mean, median, and standard deviation of the new distribution (do not use a decimal). If the distribution is not normal, use R to numerically estimate the values and express the result as a decimal (at least 3 significant figures).
Summarize your results in a table similar to the one given below. (Note that some quantities may not be well-defined mathematically. You do not have to check for this, but you can mark possible cases with asterisks.)

Answers


Yes, the distribution of a and b is normal, with mean μ=10, median m=10, and standard deviation σ=3.

The resulting distribution of a+b, a-b, a*b, and a/b will also be normal, with the following values:


 
   Operation
   Mean
   Median
   Standard Deviation

The CEO of Super Electronics asked customers to fill out a survey to win a $100 gift certificate. The customers were asked to list the products they purchased that day. 88 bought laptop computers. 52 bought desktop computers. 64 bought printers. What is the probability that the winner of the gift certificate bought a printer from Super Electronics? A.

Answers

Answer:

To calculate the probability that the winner of the gift certificate bought a printer from Super Electronics, we need to use the total number of customers who participated in the survey as the denominator and the number of customers who bought printers as the numerator.

The total number of customers who participated in the survey is:

Total Customers = Number of Customers who bought Laptops + Number of Customers who bought Desktops + Number of Customers who bought Printers

Total Customers = 88 + 52 + 64

Total Customers = 204

The number of customers who bought printers is 64.

Therefore, the probability that the winner of the gift certificate bought a printer from Super Electronics is:

P(Bought a Printer) = Number of Customers who bought Printers / Total Customers

P(Bought a Printer) = 64 / 204

P(Bought a Printer) = 0.3137 (rounded to 4 decimal places)

So, the probability that the winner of the gift certificate bought a printer from Super Electronics is 0.3137 or approximately 31.37%.
