THIS GIVES 50 POINTS

Answer:

Z'(6, 7)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.

Translation is the movement of a point up, down, right and left. If a point A(x, y) is translated a units right and b units up, the new point would ne at A'(x + a, y + b). Also, If a point A(x, y) is translated a units left and b units down, the new point would ne at A'(x - a, y - b).

Given that the coordinates of triangle XYZ is at X(7, 11), Y(10, 14) and Z(8, 7).

XYZ will be translated so that the coordinates of X, are (5,11), therefore a translation of 2 units left is done (x - 2, y). The new coordinates are:

X'(5, 11), Y'(8, 14) and Z'(6, 7)

Answer:

(10, 5)

Step-by-step explanation:

Starting coordinate : (9, 5)

x = 9 ; y = 5

Vertical distance (up and down) = y

Horizontal distance (left and right) = x

Movement to the right = positive

Movement to the left = negative

Hence, 1 unit moved to the right ; x + 1

Therefore ;

(9 + 1, 5)

= (10, 5)

Using proportional relationships, we can say that They will walk 12 laps and run 20 laps for a total of 32 miles.

In a direct proportional relationship, the output variable is found by the multiplication of the input variable and the constant of proportionality k, as follows:

y = kx.

Given that we know this, they walk 3/8 of the 8 miles that make up the complete distance. Run 5/8 of the route.

The following are the proportional relationships for the distances:

For a total distance of 32 miles, the distances walked and run are given:

therefore, They will walk 12 laps and run 20 laps for a total of 32 miles as per the proportional relation.

La ecuación estándar de la circunferencia es (x - 0.5)² + y² = 2.5².

En este problema debemos derivar la ecuación estándar de la circunferencia, cuyo diámetro está comprendido por el segmento de recta entre los puntos A(x, y) = (3, - 4) y B(x, y) = (- 2, - 4). La ecuación estándar de la circunferencia se presenta a continuación:

(x - h)² + (y - k)² = r²     (1)

Donde:

El centro de la circunferencia es el punto medio del segmento de recta AB:

(h, k) = 0.5 · (3, - 4) + 0.5 · (- 2, 4)

(h, k) = (1.5, - 2) + (- 1, 2)

(h, k) = (0.5, 0)

Y el radio de la circunferencia es la mitad de la longitud del segmento de recta AB:

\(r = \frac{1}{2}\cdot \sqrt{(-2 - 3)^{2}+[-4 - (-4)]^{2}}\)

r = 2.5

Por tanto, la ecuación estándar de la circunferencia es (x - 0.5)² + y² = 2.5².

v = (1, 0, -1) cannot be both a row of A and in the nullspace of A is a false statement.

v = (1, 0, −1)  cannot be of row A .

Let us consider the matrix A,

And v be the row of the matrix A.

Suppose that v = (1, 0, -1) is a row of a matrix A

And also lies in the nullspace of A.

Let's denote the other rows of A by R1 and R2,

Then the matrix A can be written as,

Suppose that v = (1, 0, -1) is a row of a matrix A and also lies in the nullspace of A.

A = [1, 0, -1]

      R1

      R2

Suppose Av = 0

v represents the row of the matrix.

v × v = 0

⇒ v = 0

and Av =  [1 0 -1][1]   [0]

            = [0] . [0]

            = [0]

But 1×1 + 0×0 + (-1)×(-1) = 0                

which is clearly false.

Therefore, this contradiction shows that v = (1, 0, -1) cannot be both a row of A and in the nullspace of A.

12 is the ending value of sum, if the input is: 2 5 7 3. all variables are integers.

An integer is a whole number with no fractional or decimal components. It is a subset of the real numbers, and can be either positive, negative, or zero. An integer can be written without a decimal point, and can be expressed as an exact, repeating number in a fractional or decimal form. Examples of integers include -2, 5, 0, and 17.

Integers are a special type of whole number that are used to represent counting numbers, negative numbers, and zero. They are a subset of the real numbers, which are any number that can be represented on a number line. Integers are non-fractional numbers that do not contain decimal points or other decimal components. They can be expressed as an exact number, such as -2 or 5, or as a repeating decimal or fraction, such as 3/2 or 0.75.

The answer is d. 12. To calculate the ending value of sum, we need to add up all the integers. In this case, the integers are 2, 5, 7, and 3. When added together, 2 + 5 + 7 + 3 = 17. Therefore, the ending value of sum is 17 - 5 = 12.

a proposition, The proposition is a meaningful statement. without any question,

Mathematical reasoning techniques are laid forth in the rules of mathematical logic. The father of logical reasoning was the Greek philosopher Aristotle. The theoretical foundation for many branches of mathematics, and hence computer science, is provided by logical reasoning. It is used in the design of computing devices, artificial intelligence, the definition of data structures for programming languages, and many other practical areas of computer science.

Statements to which the truth values "true" and "false" can be given are the focus of propositional logic. The objective is to evaluate these claims, either singly or collectively.

Answer:

60 sedans

Step-by-step explanation:

The computation of the number of sedans sold in 2000 is given below:

Given that

The ratio of sedans and SUV is 5:4

And, in 2010 its ratio is 2:7

Now in 2010, 84 SUVs sold

So

84 SUVS = 7

For total 9, it would be

= 84 × 9 ÷  7

= 108 vehicles

Now the number of sedans is

= 108 × 5 ÷ 9

= 60 sedans

Given:

Circles A, B, and C overlap.

The overlap of circles B and C is labeled x.

To find:

The three correct statements about x.

Solution:

It is given that the overlap of circles B and C is labeled x. It means x represent the common elements of B and C.

So, x belongs to the intersection and union of B and C.

\(x\in B\cup C\)

\(x\in B\cap C\)

Since x is the element of C, therefore it is also the element of A union C.

\(x\in A\cup C\)

The overlap of circles B and C is labeled x. It means \(x\notin A\). So,

\(x\notin A\cap C\).

Therefore, the correct options are A, B and C.

Answer:

A, B and C.

The correlation coefficient of the security X and Y returns is closest to 0.67, indicating a moderate positive correlation between the two securities.

The correlation coefficient of the security X and Y returns is closest to 0.67. This can be calculated by dividing the covariance of the returns by the square root of the product of the variances of X and Y.

The correlation coefficient measures the strength and direction of the linear relationship between two variables. It ranges between -1 and 1, with values close to 1 indicating a strong positive correlation, values close to -1 indicating a strong negative correlation, and values close to 0 indicating a weak or no correlation.

In this case, the given covariance is 10, the variance of Security X's returns is 13%, and the variance of Security Y's returns is 17%. To calculate the correlation coefficient, we use the formula:

Correlation coefficient = Covariance / (\(\sqrt{}\)(Variance_X) * \(\sqrt\)(Variance_Y))

Plugging in the values, we get:

Correlation coefficient = 10 / (\(\sqrt\)(13%) * \(\sqrt\)(17%)) ≈ 0.67

Therefore, the closest option is 0.67, indicating a moderately strong positive correlation between the returns of Security X and Security Y.

Step-by-step explanation:

Answer:

y = - \(\frac{1}{2}\) x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = A(10, - 2) and (x₂, y₂ ) = B(4, 1)

m = \(\frac{1+2}{4-10}\) = \(\frac{3}{-6}\) = - \(\frac{1}{2}\) , then

y = - \(\frac{1}{2}\) x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (4, 1 )

1 = - 2 + c ⇒ c = 1 + 2 = 3

y = - \(\frac{1}{2}\) x + 3 ← equation of line

Answer:

y = -5/2x + 5

Step-by-step explanation:

slope intercept form: y = mx + b

5x + 2y = 10 ------- subtract 5x on both sides

2y = -5x + 10 ------- divide 2 on both sides

y = -5/2x + 5
