y = 19/x^3       <===== solve for 'x'

x = cube rt (19/y)     < ====now switch the x and y's

y = cube rt ( 19/x)

Answer: f^-1(x) = 19^3/x

Step-by-step explanation:

Given that : f(x) = y = 19/x^3

x^3 = 19/y

y = (19)^3/x = f^-1(x)

The mean is sensitive to small changes in data and influenced by outliers, while the median is more stable and less affected by outliers.

The mean and median are both measures of central tendency in a data set, but they have different properties and uses. The mean is calculated by adding up all the values in the data set and dividing by the total number of values.

It is sensitive to outliers or extreme values, as even a single outlier can significantly affect the mean. For example, if we have a data set of {1, 2, 3, 4, 100}, the mean would be 22, which is greatly influenced by the outlier value of 100.

On the other hand, the median is the middle value when the data set is arranged in ascending or descending order. It is less sensitive to outliers and extreme values, making it a more stable measure of central tendency.

In the same data set {1, 2, 3, 4, 100}, the median would be 3, which is not affected by the outlier value of 100. Therefore, when a data set has outliers or extreme values, the median is often preferred over the mean as a descriptor.

In summary, the mean is sensitive to small changes in data and influenced by outliers, while the median is more stable and less affected by outliers.

So, we know that:

Every 12 hours, the population doubles.

We start with 1000 bacteria.

We want to find the number of bacteria after 72 hours (3 days).

72 / 12 = 6, so we know the population doubles 6 times.

So set up a formula:

It doubles six times, so we must do 2^6 * 1000 = P

P = 64,000 bacteria, or 6.4 x 10^4 in scientific notation.

Answer:

y = - cos ( \(\frac{3}{4}\) x + \(\frac{\pi }{4}\) )

Step-by-step explanation:

y = A cos ( Bx + C) + D

Vertical shift D = 0

A = - 1

Compression / Stretching B

Period of given function is \(\frac{8\pi }{3}\)

Period of cos x is 2π

\(\frac{8\pi }{3}\) = \(\frac{2\pi }{B}\) ⇒ B = \(\frac{3}{4}\)

Horizontal shift is C ÷ B

Horizontal shift of given function is \(\frac{\pi }{3}\)

\(\frac{\pi }{3}\) = C ÷ \(\frac{3}{4}\) ⇒ C = \(\frac{\pi }{4}\)

So, the equation of given function is

y = - cos ( \(\frac{3}{4}\) x + \(\frac{\pi }{4}\) )

\(0.5x > 4.5\)

Divide both sides by 0.5:

\(\dfrac{0.5x}{0.5} > \dfrac{4.5}{0.5}\)

Answer:

Answer:

2/5 is already a fraction.... it's an improper fraction.

The given matrix A is a 2x2 matrix.

First, we find the characteristic polynomial by taking the determinant of the matrix A minus λ times the identity matrix I:

|A - λI| =

|1-λ 2 |

| 3 2-λ| = (1-λ)(2-λ) - 2(3) = λ^2 - 3λ - 4

Thus, the characteristic polynomial of A is λ^2 - 3λ - 4.

Next, we find the eigenvalues of A by solving the characteristic polynomial:

λ^2 - 3λ - 4 = 0

(λ - 4)(λ + 1) = 0

Thus, the eigenvalues of A are λ1 = 4 and λ2 = -1.

To find the eigenvectors, we solve the system of linear equations (A - λI)x = 0 for each eigenvalue.

For λ1 = 4, we have:

(1-4)x1 + 2x2 = 0

3x1 - 2x2 = 0

Solving this system, we get the eigenvector x1 = [2, 3] (or any non-zero scalar multiple of it).

For λ2 = -1, we have:

(1+1)x1 + 2x2 = 0

3x1 + 2+1x2 = 0

Solving this system, we get the eigenvector x2 = [-1, 3] (or any non-zero scalar multiple of it).

To find an invertible matrix P such that P^-1 AP is diagonal, we construct the matrix P using the eigenvectors x1 and x2 as its columns. That is,

P = [2 -1; 3 3]

We can verify that P is invertible by calculating its determinant:

|P| = (2)(3) - (-1)(3) = 9

Since |P| is non-zero, P is invertible.

Then, we calculate P^-1:

P^-1 = (1/9)[3 1; -3 2]

Finally, we can check that P^-1 AP is diagonal:

P^-1 AP = (1/9)[3 1; -3 2][1 2; 3 2][2 -1; 3 3]

= (1/9)[12 0; 0 -1][2 -1; 3 3]

= [8/3 -4/3; -3 1]

Thus, we have found the characteristic polynomial, eigenvalues, eigenvectors, and invertible matrix P such that P^-1 AP is diagonal.

The total distance of the race will be 7.4 meters. the correct option is B.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Miguel and his brother Ario are both standing 3 meters from one side of a 25-meter pool when they decide to race. Miguel offers Ario a head start. Miguel says he will start when the ratio of Ario's completed meters to Ario's remaining meters is 1:4.

The formula for the calculation is given as,

x = ( m ) / ( m + n) ( x₂ - x₁ ) + x₁

x = ( 1 ) / ( 5 ) ( 25 - 3 ) + 3

Yes, the mysteries equal 0.06 of the total books.

Marcella said that the mysteries equal 0.06 of the total books.

To check the mysteries equal 0.06 of the total books is correct or not.

We can follow these steps:

1. Identify the total number of books and the number of mysteries: Marcella read 100 books, and 60 of them were mysteries.

2. Calculate the fraction of mysteries: Divide the number of mysteries (60) by the total number of books (100) to find the fraction of mysteries.

3. Compare the fraction with Marcella's claim: If the calculated fraction equals 0.06, then she is correct.

Now let's perform the calculations:

60 mysteries ÷ 100 total books = 0.6

Since 0.6 ≠ 0.06, Marcella's claim that the mysteries equal 0.06 of the total books is incorrect. In reality, mysteries make up 0.6 or 60% of the total books she read.

A model to support this answer could be a pie chart, where the circle represents the 100 books, and the mysteries portion is shaded in. By dividing the circle into 10 equal sections, the mysteries would fill 6 of those sections, which represents 60% of the total books.

Answer:

The equation, in slope-intercept form, of the second railroad track is y = -4x + 17.

To determine the equation of the second railroad track, we need to find the slope and y-intercept. The given information states that the second track passes through the point (2, 9).

We can calculate the slope (m) using the formula: m = (y2 - y1) / (x2 - x1), where (x1, y1) represents the coordinates of the first track (0, 32) and (x2, y2) represents the coordinates of the second track (2, 9).

Substituting the values, we have: m = (9 - 32) / (2 - 0) = -23 / 2 = -11.5.

Now that we have the slope, we can determine the y-intercept (b) using the slope-intercept form y = mx + b. Plugging in the values of the point (2, 9) and the slope (-11.5), we can solve for b:

9 = -11.5 * 2 + b

9 = -23 + b

b = 9 + 23

b = 32.

Therefore, the equation of the second railroad track in slope-intercept form is y = -11.5x + 32.
