The formula for the geometric sequence that begins with the terms 81, 54, 36, and so on is:

aₙ = 81 * (1/3)^(n-1)

To find a formula for a geometric sequence that begins with the terms 81, 54, 36, and so on, we need to determine the common ratio between consecutive terms.

By observing the sequence, we can see that each term is obtained by dividing the previous term by 3. Hence, the common ratio is 1/3.

Let's denote the first term as a₁ and the common ratio as r.

a₁ = 81 (the first term)

r = 1/3 (the common ratio)

The general formula for a geometric sequence is given by:

aₙ = a₁ * r^(n-1)

where aₙ represents the nth term of the sequence.

Substituting the values we have:

aₙ = 81 * (1/3)^(n-1)

The formula for the geometric sequence that begins with the terms 81, 54, 36, and so on is:

aₙ = 81 * (1/3)^(n-1)

Using this formula, you can find any term in the sequence by substituting the corresponding value of n.

For example, to find the 5th term of the sequence, you would substitute n = 5 into the formula:

a₅ = 81 * (1/3)^(5-1)

a₅ = 81 * (1/3)^4

a₅ = 81 * (1/81)

a₅ = 1

The 5th term of the sequence is 1.

Step-by-step explanation:

The hunter wants Sylvia to tell him where the heron is, but she​ is conflicted and does not reveal the heron's location.

This is because, from the complete text, the narration is told about the interaction between Sylvia and the hunter who she certainly likes and he offers her money to tell him the location of the heron, but when she sees the heron and enters its world, she is conflicted and does not reveal its location.

This refers to the storytelling done with the aid of a narrator to describe the events in a story, the plot, settings, and conflicts in the story.

He can tell the story from the first-person narrative, second-person narrative, limited third-person narrative, omniscient narrative, etc.

Step-by-step explanation:

I got it right in a test.

The real root of √0.25 is 0.5. A real root of a number is a number that, when multiplied by itself, equals the original number. In this case, we need to find a number that, when multiplied by itself, equals 0.25.

We can rewrite 0.25 as 25/100, or 1/4. So, the real root of √0.25 is the number that, when multiplied by itself, equals 1/4. This number is 0.5, because 0.5 * 0.5 = 1/4.

To verify our answer, we can plug 0.5 into the original expression and see if it evaluates to 0.25. We have:

√0.25 = √(25/100) = √(1/4) = 0.5

As we can see, 0.5 does indeed evaluate to 0.25. Therefore, the real root of √0.25 is 0.5.

On solving the provided question, we can say that - so, percentage - 400/500 X 100 = 80%

A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. It is frequently denoted using the percent symbol "%," though. The amount of percentages has no dimensions. With a denominator of 100, percentages are basically fractions. To show that a number is a percentage, place a percent symbol (%) next to it. For instance, if you correctly answer 75 out of 100 questions on a test (75/100), you receive a 75%. To compute percentages, divide the amount by the total and multiply the result by 100. The percentage is calculated using the formula (value/total) x 100%.

The original cost of the car was $12,935.74 (rounded to the nearest $100).

(a) To find the depreciation rate for a car that originally cost $20,000 and is worth $12,000 after 4 years, we can use the formula:

\(C = (1 - r)^n * C_0\)

where C is the value of the car after n years, C_0 is the original cost of the car, and r is the yearly depreciation rate.

Plugging in the values given, we get:

\(12,000 = (1 - r)^4 * 20,000\)

Solving for r, we get:

\(1 - r = (12,000/20,000)^(1/4) = 0.8185\)

r = 1 - 0.8185 = 0.1815

The depreciation rate for the car is 18.2% (rounded to the nearest tenth of a percent).

(b) To find the original cost of a car that has a yearly depreciation rate of 11% and is worth $10,000 after 2 years, we can use the same formula:

\(C = (1 - r)^n * C_0\)

Plugging in the values given, we get:

\(10,000 = (1 - 0.11)^2 * C_0\)

Solving for C_0, we get:

\(C_0 = 10,000 / (0.89)^2 = $12,935.74\)

The original cost of the car was $12,935.74 (rounded to the nearest $100).

Answer:

1. width = 4 inches length = 13 inches

2. 225 m²

Step-by-step explanation:

1. So we know there are two sides and one side is 9 more than the other.

We let one side be x as we don't know what the number is. The other side is x+9 as its 9 more than the first side but we don't what that is either.

We know the area of a rectangle is A = bh.

The two sides are x and x+9

so, x(x+9) = 52

x² + 9x = 52

x² + 9x - 52 = 0

x² + 13x - 4x - 52 = 0

x(x+13) -4(x+13) = 0

(x-4)(x+13) = 0

x = 4 x = 13

The answer is x = 4 because you can't have x = -13 as negative lengths don't exist.

So if one side is x and the other side is x+ 9. Then plugging in 4 to both gets us, 4 and 13 as the dimensions.

The length is 9 more than width so,

length = 13 inches and width = 4 inches.

2. We know the area of a rectangle is A = bh.

One side is x + 10 and the other is x+15

Area is 750.

(x+10)(x+15) = 750

x²+15x+10x+150 = 750

x²+15x+10x-600 = 0

x²+25x-600 = 0

(x+40)(x-15) = 0

x = 15 as we can't have x = -40 because negative distance does not exist.

The bistro has sides x and x.

So the area is x * x.

15 * 15 = 225 m².

Predictive data analytics can be used by the oil exploration company to address their problem by (a) building predictive models to identify high-potential drilling sites based on historical data and (b) using machine learning algorithms to analyze various data sources and identify patterns that lead to successful oil well locations. These approaches will help the company save costs by focusing their exploratory drilling efforts on sites with higher chances of success.

1. Building predictive models: The company can gather historical data on drilling sites, including factors such as geological features, soil characteristics, and measurements from gravitational and seismic instruments. By using this data, they can develop predictive models using machine learning algorithms.

These models will analyze the data patterns and identify the characteristics that correlate with successful oil well locations. The predictive models will provide a probability score or ranking for each potential drilling site, indicating the likelihood of finding viable oil wells.

2. Analyzing various data sources: Another approach is to utilize predictive analytics to analyze multiple data sources simultaneously. The company can integrate data from ordinance survey maps, aerial photographs, rock and soil samples, and other relevant sources.

Machine learning algorithms can be applied to identify patterns and relationships between the collected data and successful oil well locations. This analysis will help the company prioritize drilling sites based on the probability of success, reducing the need for extensive exploratory drilling.

For both proposed approaches, the data required would include historical data on drilling sites, geological features, soil characteristics, measurements from gravitational and seismic instruments, ordinance survey maps, aerial photographs, and other relevant data sources.

To utilize the insights provided by the predictive analytics solutions, the company would need the capacity to store and process large volumes of data. They would also require data analysis tools and infrastructure to run the predictive models and generate actionable insights in a timely manner.

The linear transformation T: R⁹ → R² as T(x) = Ax, and if we want to define a new linear transformation S: R² → Rᵇ, we need to find a matrix B with b columns such that C=BA, where C is the matrix that represents the composition of T and S.

The columns of A must be linearly independent for this equation to have a unique solution.

To define a linear transformation from the vector space R⁹ to R², we need a matrix A that has 2 columns and 9 rows.

Let us denote this matrix as A=[a1 a2 ... a9], where each column ai is a 9-dimensional column vector.

Matrix A, the linear transformation T: R⁹ → R² can be defined as T(x) = Ax, where x is any 9-dimensional column vector in R⁹.

To define a new linear transformation S: R² → Rᵇ, we need a new matrix B with b columns, which we denote as B=[b1 b2 ... bb].

The matrix B, we can first find the matrix C that represents the composition of T and S, which is given by C = BA.

Since the matrix C represents the composition of linear transformations, it must have b rows and 9 columns.

B must be a 2x b matrix.

Matrix a must be a b×a matrix, and the input vector x must have a dimensions (a×1) for the linear transformation t(x) = ax to be well-defined.

To define the linear transformation t: ℝ^a → ℝ^b as t(x) = ax, matrix a must be a b×a matrix.

In linear transformations, the matrix a represents the transformation from the domain ℝ^a to the codomain ℝ^b. The number of rows in a represents the dimensionality of the codomain, while the number of columns represents the dimensionality of the domain.

Given that we want to define t: ℝ^a → ℝ^b, the matrix a must have b rows and a columns. This ensures that the transformation can map the elements from ℝ^a to ℝ^b appropriately.

Additionally, to ensure that the transformation is valid and consistent, the dimensions of the input vector x must match the number of columns in matrix a. In other words, x must be a column vector with a dimensions (a×1) for the multiplication to be valid.

First, convert 1 1/3 to improper fraction:

1 1/3 = 4/3

Second, make denominator the same by multiplying 4/3 by 2/2:

4/3 * 2/2 = 8/6

Third, subtract:

8/6 - 5/6 = 3/6

Fourth, simplify:

3/6 = 1/2

The correct answer for the difference between \(1\dfrac{1}{3}\)  and \(\dfrac{5}{6}\)  is  \(\dfrac{1}{2}\) .

Given expression:

\(1\dfrac{1}{3} - \dfrac{5}{6}\)

convert \(1\dfrac{1}{3}\)  to an improper fraction:

\(1\dfrac{1}{3} = \dfrac{3*1 + 1}{3}\)
