Rotate this image 180° clockwise around the point (–2, 1):

The set of items that are part of both sets F and G is indicated by the symbol F G. It is the group of equilateral triangles that are also isosceles triangles, to put it another way.

Due to its three congruent sides, every equilateral triangle is an isosceles triangle. F G = F hence equals "equilateral triangles." By eliminating the unnecessary component, we can make F G simpler.

Consequently, F G = "equilateral triangles"

When seen collectively, a set is a group of items. The elements or members of the set are the things that make it up. Any mathematical object, such as integers, functions, or other sets, may be one of the elements of a set.

Answer: If Hue can form 2 rows of a given length with 3 chairs left over, we can represent this as:

2x + 3 = chairs in that row length

Also, if she can form 8 rows of that same length if she gets 15 more chairs, we can represent this as:

8x + 15 = chairs in that row length

Since the number of chairs in that row length is the same in both equations, we can set them equal to each other:

2x + 3 = 8x + 15

To solve for x, we can subtract 3 from both sides:

2x = 8x + 12

Then we can subtract 2x from both sides:

6x = 12

Finally, we can divide both sides by 6:

x = 2

So the number of chairs in that row length is 2x + 3 = 2(2) + 3 = 7.

The degree measure of the smaller angle formed by the hands of a clock at 10 O'clock is 60°.

The degree measure of a full circle is 360 degrees. The clock face is divided into 12 equal parts, or 30-degree increments, for the hours. At 10 o'clock, the hour hand would point to the 10 on the clock face, and the minute hand would point to the 12.

This makes them 1/6th of a circle apart, and (1/6) * 360° = 60°.

The angle between the two hands would be formed by the distance between the 10 and the 12, which is 60 degrees.

Comparing rounding and compatible number, rounding gives a closer estimate than compatible number.

While compatible numbers are those that are simple to multiply mentally, rounding entails reducing one or both of the numbers to a close "friendly" number.

Estimating the result of 48 x 123 can be done using compatible integers and rounding.

Compatible numbers make it simpler to find an estimate calculation because they are close in value to the real number. A multiplication issue is presented here. By rounding the values to the closest hundreds place, you can obtain an approximation of the product. 400 and 100 are equivalent to 395 and 103.

1) Using compatible numbers :

48 = 50

123 = 100

50 × 100 = 5000

2) By rounding numbers :

48 = 50

123 = 120

50 × 120 = 6000

6000 is closer to the actual value of the product than 5000 ;

Therefore, rounding gives a closer estimate than compatible number.

In general, the maximum order of the spectrum that can be observed with a diffraction grating is limited by the grating equation.

This equation states that mλ = d(sinθi - sinθr), where m is the order of the diffraction, λ is the wavelength of light, d is the spacing between the grating lines, θi is the angle of incidence, and θr is the angle of diffraction. Since d is fixed and θi is typically kept constant, the maximum order of the spectrum that can be observed is limited by the angle of diffraction (θr). This angle can be calculated using the equation θr = sin-1[(mλ/d)+sinθi]. Thus, the maximum order of the spectrum is limited by the value of θr, which is determined by the wavelength of light and the spacing between the grating lines.

Answer: a) To calculate the total rate of return if Josh invests the same amount in each company, we need to add up the individual rates of return from each company and divide by the number of companies.

The total rate of return for the four companies is: (7.62% + -4.17% + -0.83% + 3.70%) / 4 = 2.52%

So the total rate of return if Josh invests the same amount in each company is 2.52%.

b) To calculate the total rate of return if Josh invests three times as much in Stiller Co. as in the other companies, we need to multiply the rate of return for Stiller Co. by 3 and add it to the rates of return for the other companies.

The total rate of return for the four companies is: (-4.17% x 3) + 7.62% + -0.83% + 3.70% = -7.32%

So the total rate of return if Josh invests three times as much in Stiller Co. as in the other companies is -7.32%.

It's important to note that the answer may change if the investment amount on each company is different.

What is a pie chart?

One sort of graph that illustrates the information in the circular graph is a pie chart. It is a sort of graphical representation of data where the slices of pie depict the relative sizes of the data. A list of numerical and categorical variables is necessary for a pie chart. Pie in this context refers to the entire thing, and slices to its component portions.

The rent charges is = GH¢ 80.00

The savings can be obtained by ratio method -

Savings is depicted by 24° and rent by 96° in the pie chart.

So, the ratio will be 24/96.

Then the savings value will be -

(24/96) × 80

(1/4) × 80

20

Therefore, the savings value is GH¢ 20.00.

The total angle of pie chart is 360°.

Savings is depicted by 24°, rent by 96°, entertainment by 48° and clothing by 48° in the pie chart.

The angle for food will be -

360° - (24° + 96° + 48° + 48°)

360° - 216°

144°

Now the fraction that is for food -

144/360

2/5

Therefore, food covers 2/5 part of pie chart.

The amount spent on food can be obtained by formula of angle sector -

We first thought of a matrix as a rectangular array of numbers. When the number of rows is m and columns is n, we say that the dimensions of the matrix are m×n.

A vector is most simply thought of as a matrix with a single column. There are two operations we can perform with vectors: scalar multiplication and vector addition. Both of these operations have geometric meaning.

Given a set of vectors and a set of scalars we call weights, we can create a linear combination using scalar multiplication and vector addition.

The product of two matrices can be seen as the result of taking linear combinations of their rows and columns. This way of interpreting matrix multiplication often helps to understand important results in matrix algebra.

Problem 22

The smaller inner circle has a radius of r = 5. That will be plugged into the circumference formula below.

C = 2pi*r

C = 2pi*5

C = 10pi

This is the exact distance around the circle in terms of pi. Think of it like the amount of fencing you need to enclose the circle.

If you want an approximate perimeter, then use something like pi = 3.14

So 10pi = 10*3.14 = 31.4 cm is the approximate perimeter aka circumference of the smaller circle.

-------------

The larger circle is the same idea. The radius is r = 5+5 = 10 cm

C = 2pi*r

C = 2pi*10

C = 20pi .... exact circumference

C = 20*3.14

C = 62.8 ... approximate circumference

Use more decimal digits of pi to get a more accurate value.

===================================================

Problem 23

The smaller circle has a diameter of 9 ft, which means the radius is r = 9/2 = 4.5 ft

C = 2pi*r

C = 2pi*4.5

C = 9pi .... exact circumference

C = 9*3.14

C = 28.26 .... approximate circumference

The units of the circumference are in feet

-------------

The larger circle has radius r = 4.5+2.5 = 7 ft

C = 2pi*r

C = 2pi*7

C = 14pi .... exact circumference

C = 14*3.14

C = 43.96 .... approximate circumference

===================================================

Problem 24

The larger circle has radius 22. This radius is the diameter of the smaller circle.

So the smaller circle has radius 22/2 = 11

C = 2pi*r

C = 2pi*11

C = 11pi .... exact circumference

C = 11*3.14

C = 34.54 .... approximate circumference

The circumference units are "meters".

-------------

Now onto the larger circle

C = 2pi*r

C = 2pi*22

C = 44pi .... exact circumference

C = 44*3.14

C = 138.16 .... approximate circumference

Step-by-step explanation:

Markup is what a store adds to the price they paid in order to come up with a selling price.

store selling price = cost to store + markup

Store purchase price: $993

Store markup of 200%: 200% of $993 = 2 × $993 = $1986

Store selling price: $993 + $1986 = $2979

14% tax: 14% of $2979 = 0.14 × $2979 = $417.06

Total selling price including markup & sales tax: $2979 + $417.06 = $3396.06

The partials ∂y/∂x = 1 and ∂z/∂x = -1, so we get the Reciprocal Theorem.

Reciprocity Theorem: Let F(x, y, z) be a continuous function of x, y, and z, then we have

∂F/∂x = (∂F/∂y)x - (∂F/∂z)y

This is proven by writing the condition of F(x, y, z) = 0 into explicit forms x-x(y,z) or z-z(x,y). Then from the chain rule, we have

∂F/∂x = (∂F/∂y)(∂y/∂x) + (∂F/∂z)(∂z/∂x)

And since x = x(y,z) and z = z(x,y), the partials ∂y/∂x = -1 and ∂z/∂x = 1, so we get the Reciprocity Theorem.
