Car 12 of Train B is also 12 cars away from Car 19 on Train B.

Since each train boasts 31 cars, we can ascertain the total amount of vehicles between Car 19 and Car 12 on Train A:

31 - 19 = 12

Thus, Car 12 on Train A is a dozen units distant from Car 19 on Train A.

Nevertheless, Train B is furthermore moving in an inverring direction and has its exclusive set of automobiles between Car 19 and Car 12. We comprehend that the matching figure of cars must be amongst Car 19 and Car 12 on Train B as with Train A.

In essence, Car 12 of Train B is also 12 cars away from Car 19 on Train B.

The equation 2 log₅ x = log₅ 4 + log₅ 9 has two solutions: x = 6.

To solve the equation 2 log₅ x = log₅ 4 + log₅ 9, we can use logarithmic properties to simplify and find the value of x.

Using the properties of logarithms, we can rewrite the equation as follows:

2 log₅ x = log₅ (4 * 9)

Next, we simplify the right side:

2 log₅ x = log₅ (36)

Now, we can use the property of logarithms that states logₐ b = c is equivalent to aᶜ = b. Applying this property, we have:

x² = 36

Taking the square root of both sides, we get:

x =  √36

Since the square root of 36 can be either positive or negative, we have two possible solutions:

x = 6

It's important to note that when working with logarithmic equations, we must always check if the obtained solutions satisfy the domain restrictions of the original equation. In this case, since the logarithm has a base of 5, the solution x = 6.

a) To re-express the given differential equation as a first-order differential equation using matrix and vector notation, we can rewrite it in the form:

\(x' = Ax\)

where x is a vector and A is a square matrix.

b) To determine the stability of the system obtained in part (a), we need to analyze the eigenvalues of matrix A.

If all eigenvalues have negative real parts, the system is stable.

If at least one eigenvalue has a zero real part, the system is neutrally stable.

If at least one eigenvalue has a positive real part, the system is unstable.

c) To compute the eigenvalues and eigenvectors of matrix A, we solve the characteristic equation

\(det(A - \lambda I) = 0\),

where λ is the eigenvalue and I is the identity matrix.

By solving this equation, we obtain the eigenvalues.

Substituting each eigenvalue into the equation

\((A - \lambda I)v = 0\),

where v is the eigenvector, we can solve for the eigenvectors.

d) Once we have computed the eigenvalues and eigenvectors of matrix A, we can construct the diagonalization relationship as follows:

\(A = PDP^{(-1)}\)

where P is a matrix whose columns are the eigenvectors of A, and D is a diagonal matrix whose diagonal elements are the eigenvalues of A.

To show that this relationship is valid, we can compute \(PDP^{(-1)}\) and verify that it equals A.

Answer:

I think that it may be the last one

Step-by-step explanation:

Answer:

y=5x+44

Step-by-step explanation:

Parallel lines have equal gradients therefore the line will have a gradient =5

Substitute the gradient into the equation y= mx+c. You'll get something like this: y=5x+c

Substitute the given point into the equation. You'll get something like this: 9=5(-7)+c

Calculate the value of c. You'll get 44 as the value of c.

Then substitute the value of c into the original equation. You'll get y= 5x+44

Answer:

\(\mathbf{L(x)= ( - \dfrac{1}{3})x^3 + 45x^2 -200x +31000}\)

Step-by-step explanation:

From the given information:

Let assume the population is denoted by L

The rate of change of the young adults per year given  can be represented as;

\(\dfrac{dL}{dx}= -x^2 +90x - 200\)

where;

x = 0 since 2010

\(dL = -x^2 +90x -200 dx\)

\(L = \int( -x^2 +90x -200 ) \ dx\)

\(L = - \dfrac{1}{3}x^3 + 45x^2 -200x +C\)

here;

L(0) = 31000

∴

\(- \dfrac{1}{3}(0)^3 + 45(0)^2 -200(0)+C= 31000\)

C = 31000

\(\mathbf{L(x)= ( - \dfrac{1}{3})x^3 + 45x^2 -200x +31000}\)

The simplified form of -20/2(7 2/3) is -230/3.

To solve the expression -20/2(7 2/3), we need to follow the order of operations, which states that we should perform the operations inside parentheses first, then any multiplication or division from left to right, and finally any addition or subtraction from left to right.

First, let's convert the mixed number 7 2/3 to an improper fraction.

7 2/3 = (7 * 3 + 2) / 3 = 23/3

Now, let's substitute the value back into the expression:

-20/2 * (23/3)

Next, we simplify the multiplication:

-10 * (23/3)

To multiply a fraction by a whole number, we multiply the numerator by the whole number:

-10 * 23 / 3

Now, we perform the multiplication:

-230 / 3

Therefore, the simplified form of -20/2(7 2/3) is -230/3.

The height of a woman whose femur (f) measures 49 centimeters is equal to 173.15‬ centimeters.

A function can be defined as a mathematical expression that defines and represents the relationship that exists between two or more variable of a data set.

In order to determine the height of a woman whose femur (f) measures 49 centimeters, we would substitute this numerical value into the first function as follows:

G(f) = 2.57f + 47.22

G(49) = 2.57(49) + 47.22

G(49) = 125.93 + 47.22

A sequence of transformations that would map PQ onto RS include the following: A. a 90° clockwise rotation about the origin, then a reflection in the x-axis.

In Mathematics and Geometry, a reflection over the x-axis is represented by this transformation rule (x, y) → (x, -y). This ultimately implies that, a reflection over or across the x-axis would maintain the same x-coordinate while the sign of the x-coordinate changes from positive to negative or negative to positive.

For a 90° clockwise rotation about the origin, the new coordinates of P is given by:

(x, y)            →      (y, -x)

P (-6, 10)      →      (10, -(6)) = P' (10, -6)

Next, we would apply a reflection over or across the x-axis;

(x, y)                →      (x, -y)

P' (10, -6)       →      (10, -(-6)) = S (10, 6)

It says he wrote checks for 20 dollars and 30 dollars, which takes away 20 dollars and then 30 more dollars, then he deposited 40 more dollars.

Step-by-step explanation:

The vertices of the similar figure that results from the dilation and translation will be A'' = (2a - 1, 2b), B'' = (2c - 1, 2b), C'' = (2c - 1, 2d), and D'' = (2a - 1, 2d).

Assume that the rectangle's four vertices are A, B, C, and D, with the corresponding coordinates being (a, b), (c, b), (c, d), and (a, d).

First, enlarge the rectangle.

We must multiply the coordinates of each vertex by the scale factor of two in order to enlarge the rectangle. We can apply the following formulas because the centre of dilation is at (0, 0):

Old x-coordinate + 2 equals the new x-coordinate

Old y-coordinate + 2 times the new y-coordinate

Therefore, following dilation, the new coordinates for the vertices will be: A' = (2a, 2b)

B' = (2c, 2b)

C' = (2c, 2d)

D' = (2a, 2d)

Translate the Figure in Step 2

The x-coordinate of each vertex must be reduced by one in order to translate the figure one unit to the left. Therefore, following translation, the vertices' new coordinates will be: A' = (2a - 1, 2b)

B'' = (2c - 1, 2b)

C'' = (2c - 1, 2d)

D'' = (2a - 1, 2d)

As a result, A'' = (2a - 1, 2b), B'' = (2c - 1, 2b), C'' = (2c - 1, 2d), and D'' = (2c - 1, 2d) will be the vertices of the similar figure that comes from the dilation and translation. (2a - 1, 2d).

Answer: 16 guests

144-44=100. 144/36=4 tarts a guests. +1=5 tarts a guests. 100/5=20.

16 guests were absent to the party.

Given that Peter ordered 12 boxes of egg tarts.

Each box contains 12 tarts, so initially, there were a total of 12 * 12 = 144 tarts.

There were 36 guests invited for the party.

Each guest was supposed to receive an equal share, which would be 144 tarts / 36 guests = 4 tarts per guest.

There were 44 egg tarts left after the party.

The guests who attended ate one more egg tart than originally planned.

So, for the guests who attended, they ate 4 + 1 = 5 tarts each.

To determine the number of guests who attended, we can divide the total number of tarts eaten by the number of tarts per guest:

Total tarts eaten = 144 tarts - 44 tarts

= 100 tarts

Number of guests who attended = 100 tarts / 5 tarts per guest = 20 guests.

Since there were originally 36 guests invited, and 20 guests attended, the number of guests who were absent would be 36 guests - 20 guests = 16 guests.
