What are the coordinates of the image a ABC after a dilation with center (0,0) and a scale factor of 3? Explain how you got your answers.​

Answer:

x = 30, y = 15

Step-by-step explanation:

x = 2*15 = 30

(Central angle is twice the inscribed angle standing on the same arc.)

Similarly,

y = 15

(Base angles of isosceles triangle are equal)

Part (a)

\(v=22(3)^{d/10}\)

Part (b)

We can rewrite the function as \(v=22(3^d)(3^{1/10})\). Thus, the percentage is \(100(1-3^{1/10})=11.6\%\)

A model for the number of views, v, as a function of the number of days, d, since there were 22 views is \(v = 22(3)^{d/10}\) and the views increasing per day by 11.6%.

Exponential growth is a pattern of data that shows greater increases with passing time, creating the curve of an exponential function.

Given that, The total views of an online video are tripling every ten days. Initially there are 22 views of the video, v represents the number of views and d represents days

a) Since the number of views are tripling every ten days, so, the function will be =  \(v = 22(3)^{d/10}\)

b) We have function \(v = 22(3)^{d/10}\)

So, percentage = \(100(1-3^{1/10})\) = 11.6%

Hence, A model for the number of views, v, as a function of the number of days, d, since there were 22 views is \(v = 22(3)^{d/10}\) and the views increasing per day by 11.6%.

Answer:

Subtract the circle from the square

Step-by-step explanation:

(10× 10) - 25pi

Answer:

= 1799   or   224.875

     8

Step-by-step explanation:

5³ − (6/48) + 10²

= 125 - (0.125) + 100

= 224.875

or

5³ − (6/48) + 10²

= 125 - 1/8 + 100

= -1/8 + 225

= (225 * 8)/8 - 1/8

= (225 * 8-1) / 8

= 1799   or   224.875

     8

Answer:

\(\huge \boxed{\frac{1799}{8} }\)

\(\rule[225]{225}{2}\)

Step-by-step explanation:

\(\displaystyle 5^3-(\frac{6}{48} )+10^2\)

Solving for exponents:

False. Time-series models do not rely on judgment in an attempt to incorporate qualitative or subjective factors into the forecasting model.

One of the most often used methods of data science in business, finance, supply chain management, production, and inventory planning is time series forecasting. A time component is often present in prediction difficulties, necessitating the extension of time series data or time series forecasting. Another crucial field of machine learning (ML) is time series forecasting, which may be viewed as a supervised learning issue.

Time series models are utilized to forecast events. Moving average, smooth-based, and ARIMA are common example types. It's important to choose the model that works best depending on the unique time series because not all models will produce similar outcomes for the comparable dataset.

Trend analysis, regression analysis, and time series models are the three categories of forecasting models. To determine whether the data exhibits a long-term trend, trend analysis is utilized.

Answer:

The surface area of the triangular prism is 84 square centimeters.

Step-by-step explanation:

The surface area of a figure is exactly what it means, the area of its outer surface or the added areas of each face that makes the figure.

Nets are a way to find surface area easier because it is an outline of the faces of the 3d figure.

But since we don’t have a net, we will just find the area of each face that forms this right triangular prism:

The two congruent triangular bases:

1/2 x 4 x 3 = 6 cm^2

6 x 2 = 12 cm^2

Lateral bottom rectangular face:

6 x 3 = 18 cm^2

Lateral to the right rectangular face:

5 x 6 = 30 cm^2

Lateral to the left rectangular face:

4 x 6 = 24 cm^2

Add up all the values:

12 + 18 + 30 + 24 = 84

The SA is 84 square centimeters

Answer:

The direction angle for the vector measured clockwise from the positive x-axis is approximately 105.001°.

Step-by-step explanation:

Let be \(P(x,y)\) a point containing the components of a vector, the direction angle for the vector regarding origin (\(\theta\)), in sexagesimal degrees, is determined by the following formula:

\(\theta = \tan^{-1} \frac{y}{x}\) (1)

Where:

\(x\) - x-coordinate of the point P.

\(y\) - y-coordinate of the point P.

Let consider that \(P(x,y) = (-7.765, 28.978)\). After a quick inspection, we note that vector stands in the 2nd Quadrant (\(x < 0 , y > 0\)). Then, the direction of the angle with respect to the positive x semiaxis is:

\(\theta = \tan ^{-1} \left(\frac{28.978}{-7.765} \right)\)

\(\theta \approx 105.001^{\circ}\)

The direction angle for the vector measured clockwise from the positive x-axis is approximately 105.001°.

Angle the given vector makes with the positive x-axis when measured counterclockwise is required.

The direction of the angle for the vector measured counterclockwise from the positive x-axis is 105°. The calculations have been shown below by using the concepts of vector.

The given vector is (-7.765,28.978)

The angle is found by the formula

\(\theta=\tan^{-1}\dfrac{y}{x}\)

Here,

y = 28.978

x = -7.765

Substituting the given values we get

\(\theta=\tan^{-1}\dfrac{28.978}{-7.765}=-74.99=-75^{\circ}\)

So, the required angle is

\(180-75=105^{\circ}\)

In the given list, the students with marks greater than 45 are: 50, 49, 47, 48, 49, 48, 47, 49, 48, 50, 47, 49, 48, 46, 47, 48, 47.

Counting these numbers, we find that there are 17 students who obtained more than 45 marks.

b) To find the number of students getting less than 45 marks, we count the students whose marks are less than 45 in the given list.

In the given list, the students with marks less than 45 are: 44, 44, 42, 41, 41, 42, 41, 44, 44, 42, 45, 45, 45, 44, 45.

Counting these numbers, we find that there are 15 students who obtained less than 45 marks.

c) To find the maximum number of students getting the same marks, we look for the mark that appears most frequently in the given list.

In the given list, the marks obtained by the students are: 44, 50, 44, 49, 42, 47, 45, 42, 44, 48, 49, 48, 47, 49, 47, 41, 45, 48, 41, 48, 41, 42, 47, 49, 49, 48, 50, 47, 49, 48, 46, 44, 45, 45, 46, 44, 42, 47, 48, 45.

Counting the frequency of each mark, we find that the marks 47 and 48 appear most frequently, with a count of 6 each. Therefore, the maximum number of students getting the same marks is 6.

d) To find the average marks obtained by the students in the class, we sum up all the marks and divide by the total number of students.

Total marks = 44 + 50 + 44 + 49 + 42 + 47 + 45 + 42 + 44 + 48 + 49 + 48 + 47 + 49 + 47 + 41 + 45 + 48 + 41 + 48 + 41 + 42 + 47 + 49 + 49 + 48 + 50 + 47 + 49 + 48 + 46 + 44 + 45 + 45 + 46 + 44 + 42 + 47 + 48 + 45

           = 1912

Total number of students = 40

Average marks = Total marks / Total number of students

                 = 1912 / 40

                 = 47.8

Therefore, the average marks obtained by the students in the class is 47.8.

e) To find the number of students getting more than the average marks, we count the students whose marks are greater than 47.8.

In the given list, the students with marks greater than 47.8 are: 50, 50, 49, 48, 49, 48, 49, 48, 50, 49, 49, 48, 48, 50, 49, 49, 48, 48, 47, 49, 49, 48, 50, 47,

49, 49, 48, 50, 47, 49, 49, 48, 48, 49, 48, 47, 48, 49, 49, 48, 50, 49.

Counting these numbers, we find that there are 40 students who obtained more than the average marks.

A circle having radius 5 and centre at (0,0) has equation x² + y² = 25.

What is the equation of circle?

A circle is a closed curve that extends outward from a set point known as the centre, with each point on the curve being equally spaced from the centre. A circle with a (h, k) centre and a radius of r has the equation:

(x-h)² + (y-k)² = r²

Let (x,y) be any point on the circle.

Given that centre of the circle is origin (0,0).

Now, we know that the distance from any point on the circle to the centre is equal to the radius of the circle.

So, distance between point (x,y) and centre (0,0)  is equal to radius of the circle which is given 5 units.

Now, using the distance formula -

√[(x - 0)² + (y - 0)²] = 5

Squaring on both the sides of the equation -

(x - 0)² + (y - 0)² = 25

So, the equation of the circle with radius 5, centred at the origin is x² + y² = 25.

Therefore, the equation is x² + y² = 25.

Step-by-step explanation:

(12)B > 180

Her goal is to make more than 180 so if she wants to sell each book for $12 then so if she sells 14 books or above she would get more than $180.

So B could equal anything 16 and above but in my case I chose 24

(12)24 = 288 > 180

So write a equation like mine that equals a number that's greater than 180. Keep in mind each book sells for $12 each. Then solve for B which is how many books she has to sell to get the number greater than 180.
