Dilation involves changing the size of the polygon

The best rule of dilation is \((x,y) \to \frac 72(x,y)\)

The coordinates of vertices Q and Q' are given as;

Q = (6,2)

Q' = (21, 7)

The scale factor of dilation is then calculated as:

\(k = \frac {Q'}{Q}\)

So, we have:

\(k = \frac {(21,7)}{(6,2)}\)

Factorize

\(k = \frac {7/2(6,2)}{(6,2)}\)

Divide

\(k = \frac {7}2\)

So, the transformation rule is:

\((x,y) \to \frac 72(x,y)\)

Hence, the best rule of dilation is \((x,y) \to \frac 72(x,y)\)

Step-by-step explanation:

Cost for the coffee + Cost for the bagel

$1.39 + $1.85

$3.24

Solution :

According to the question, first we need to assume a variable for the dryer then we need to add $79 with the variable for getting the washer, after which doing their total we can get the value

Let's assume The Dryer be x

Now,

The washer is $79 more than that of the dryer

So, the washer be x + $79

Total cost $1029

Getting variable's value

Now, Cost of dryer = x = $475

★ Therefore, the cost of Dryer is $475 ★

By applying the theory of separable ordinary differential equations we conclude that the solution of the differential equation \(\frac{dy}{dx} \cdot (\ln y)^{2} + y\cdot \sqrt{x} = 0\) with y(0) = e is \(y = e^{\sqrt [3]{-2\cdot x^{\frac{3}{2} }+1}}\).

In this question we must separate each variable on each side of the equivalence, integrate each side of the expression and find an explicit expression (y = f(x)) if possible.

\(\frac{dy}{dx} \cdot (\ln y)^{2} + y\cdot \sqrt{x} = 0\)

\((\ln y)^{2}\,dy = -y \cdot \sqrt{x}\, dx\)

\(-\frac{(\ln y)^{2}}{y}\, dy = \sqrt{x} \,dx\)

\(-\int {\frac{(\ln y)^{2}}{y} } \, dy = \int {\sqrt{x}} \, dx\)

If u = ㏑ y and du = dy/y, then:

\(-\int {u^{2}\,du } = \int {x^{\frac{1}{2} }} \, dx\)

\(-\frac{1}{3}\cdot u^{3} = \frac{2\cdot x^{\frac{3}{2} }}{3} + C\)

\(u^{3} = -2\cdot x^{\frac{3}{2} } + C\)

\((\ln y)^{3} = - 2\cdot x^{\frac{3}{2} } + C\)

\(C = (\ln e)^{3}\)

\(C = 1\)

And finally we get the explicit expression:

\(\ln y = \sqrt [3]{-2\cdot x^{\frac{3}{2} }+ 1}\)

\(y = e^{\sqrt [3]{-2\cdot x^{\frac{3}{2} }+1}}\)

By applying the theory of separable ordinary differential equations we conclude that the solution of the differential equation \(\frac{dy}{dx} \cdot (\ln y)^{2} + y\cdot \sqrt{x} = 0\) with y(0) = e is \(y = e^{\sqrt [3]{-2\cdot x^{\frac{3}{2} }+1}}\).

Answer: Barry's Swimwear sold a greater fraction of the bathing suits in stock as long as the store had fewer than 72 bathing suits in stock.

Step-by-step explanation:

Barry's Swimwear sold 15 out of an unknown number of bathing suits in stock, so we can express this fraction as 15/x, where x is the total number of bathing suits in stock at Barry's Swimwear. Similarly, Philip's Sun Wear sold 5 out of 72 bathing suits in stock, so we can express this fraction as 5/72.

To compare these two fractions, we need to express them with a common denominator. One way to do this is to find the least common multiple of the two denominators, which in this case is 72. To express 15/x with a denominator of 72, we can multiply both the numerator and the denominator by a factor of 72/x. This results in the fraction 15*(72/x)/72 = 15/x. Similarly, we can express 5/72 with a denominator of 72 by multiplying both the numerator and the denominator by a factor of 72/72, which results in the fraction 5*(72/72)/72 = 5/72.

Now that we have both fractions expressed with a common denominator of 72, we can compare them directly. 15/x is greater than 5/72 as long as x is less than 72. This means that Barry's Swimwear sold a greater fraction of the bathing suits in stock as long as the store had fewer than 72 bathing suits in stock.

Answer:

Part A:

To find the percentage of survey respondents who liked neither hamburgers nor burritos, we need to calculate the frequency in the "Does not like hamburgers" and "Does not like burritos" categories.

Frequency of "Does not like hamburgers" = Total in "Does not like hamburgers" category = 135

Frequency of "Does not like burritos" = Total in "Does not like burritos" category = 54

Total respondents who liked neither hamburgers nor burritos = Frequency of "Does not like hamburgers" + Frequency of "Does not like burritos" = 135 + 54 = 189

Percentage of survey respondents who liked neither hamburgers nor burritos = (Total respondents who liked neither hamburgers nor burritos / Total respondents) x 100

Percentage = (189 / 205) x 100 = 92.2%

Therefore, 92.2% of the survey respondents liked neither hamburgers nor burritos.

Part B:

To find the marginal relative frequency of all customers who like hamburgers, we need to divide the frequency of "Likes hamburgers" by the total number of respondents.

Frequency of "Likes hamburgers" = 110 (given)

Total respondents = 205 (given)

Marginal relative frequency = Frequency of "Likes hamburgers" / Total respondents

Marginal relative frequency = 110 / 205 ≈ 0.5366 or 53.66%

Therefore, the marginal relative frequency of all customers who like hamburgers is approximately 53.66%.

Part C:

To determine if there is an association between liking burritos and liking hamburgers, we can compare the joint and marginal frequencies.

Joint frequency of "Likes hamburgers" and "Likes burritos" = 29 (given)

Marginal frequency of "Likes hamburgers" = 110 (given)

Marginal frequency of "Likes burritos" = 70 (calculated by adding the frequency of "Likes burritos" in the table)

To assess the association, we compare the ratio of the joint frequency to the product of the marginal frequencies:

Ratio = Joint frequency / (Marginal frequency of "Likes hamburgers" x Marginal frequency of "Likes burritos")

Ratio = 29 / (110 x 70)

Ratio ≈ 0.037 (rounded to three decimal places)

A three-dimensional structure called a rectangular prism has six faces, each of which is a rectangle. It is also referred to as a rectangular parallelepiped or a rectangular cuboid. In commonplace items like boxes, buildings, and furniture, rectangular prisms are utilised frequently in geometry, architecture, and engineering. A rectangular prism's surface area may be determined by adding the areas of all six sides, while its volume can be estimated by multiplying its length, width, and height.

18. The net of the rectangular prism is given by option a.

19. The surface area of the basket is given as:

The area of the front and back faces is = (19) x (10) = 190 cm² each.

Each piece Measurement of an angle of 120 degrees cut into nine equal lengths with a kerf width of 0.125 would be 14.4583 degrees.

When a particular angle is cut into nine equal parts, the measure of each piece needs to be calculated.

Therefore, it is essential to first calculate the total angle measure and then divide it by the number of parts into which it is being cut.

What is an Angle?

An angle is a geometrical shape that consists of two rays sharing a common endpoint. The common endpoint is known as the vertex, and the two rays are known as the arms of the angle. An angle can be measured in degrees, radians, or gradians. Degrees are the most commonly used unit of measuring angles.How to Calculate Each Piece Measurement of an Angle if Cut into 9 Equal Lengths

To determine each piece measurement of an angle if cut into nine equal lengths, we will need to carry out the following steps:

Step 1: Calculate the total angle measure Suppose the angle being cut into nine equal lengths is an obtuse angle measuring 120 degrees. In that case, the total angle measure will be 120 degrees.

Step 2: Divide the total angle measure by the number of parts into which it is being cut.120 degrees ÷ 9 = 13.3333 degrees

Step 3: Add the kerf width to the piece measurements.0.125 x 9 = 1.125 degrees13.3333 + 1.125 = 14.4583 degrees

Therefore, each piece measurement of an angle of 120 degrees cut into nine equal lengths with a kerf width of 0.125 would be 14.4583 degrees.

The complete subtraction problem is given by the image at the end of the answer.

In this problem, we have to complete the subtraction problem given on the image at the end of the answer.

The subtraction starts from the last decimal digit, hence:

2 - 0 = 2.

Then, from the first decimal digit, we have that:

x - 8 = 3.

x = 11.

A single digit cannot be written as 11, hence it will be written as 1 plus 10 taken from the unit digit of the integer part.

Then the subtraction at the unit digit of the integer part will be of:

3 - 9 = ... (3 because one was taken for the decimal part).

Hence one is taken from the tenths digit, and the equivalent subtraction is:

13 - 9 = 4.

Hence these terms become known:
