Answer:

  none of the above

Step-by-step explanation:

All of these abbreviations represent postulates that can be used to prove congruence. The HL postulate only applies to right triangles, but all of the others apply to any shape triangle.

All can be used to show congruence.

The resulting vectors after performing the given operations on vectors u and v. are as follow;

2u = 12i.

-3v = -27i + 9j,

u + v = 15i - 3j,

3u - 4v = 18i + 12j

To find 2u, we multiply each component of vector u by 2. Since u = 6i, multiplying each component by 2 gives us 2u = 12i.

To find -3v, we multiply each component of vector v by -3. Since v = 9i - 3j, multiplying each component by -3 gives us -3v = -27i + 9j.

To find u + v, we add the corresponding components of vectors u and v. Since u = 6i and v = 9i - 3j, adding the components gives us u + v = 6i + 9i - 3j = 15i - 3j.

To find 3u - 4v, we multiply each component of vector u by 3 and each component of vector v by -4, and then add the corresponding components. Since u = 6i and v = 9i - 3j, multiplying and adding the components gives us 3u - 4v = 3(6i) - 4(9i - 3j) = 18i + 12j.

Here, we have been given damping ratio values for different period values. Our objective is to compare the correlation coefficient values of the three regression models and determine the best one.

We will do this by using Excel or Matlab's analysis tools. Here, we can clearly see that the damping ratio is non-linearly related to the period. In this case, we will fit a non-linear model which is capable of predicting the damping ratio for given period values. We will start by plotting a scatter plot of the given data. Based on the scatter plot, we can conclude that a non-linear model will be the best fit.  

From the given table, we will first plot a scatter plot for the given damping ratio values against their corresponding period values. This will help us visualize the relationship between the two variables and select the best regression model. Here, we can clearly see that the damping ratio is non-linearly related to the period.

Answer:

The solutions are 0 and 3

Step-by-step explanation:

x = 3-y

((3-y)^2+y^2)=9

=(y^2-6y+9)+y^2) = 9

= 2y^2 - 6y +9 -9 =0

=2y^2 -6y=0

= y*(2y -6) = 0

y1=0 y2=3

The solution of the system x + y = 3 and x² + y² = 9 is y = 0 and y = 3.

A formula known as an equation uses the equals sign to denote the equality of two expressions.

Given:

x + y = 3

x² + y² = 9

Solve the equation as shown below,

x = 3 - y

Put this value of x in the second equation,

The image A'(4, 6) is the result of dilation of the original point A(2, 3) by a scale factor 2 with a center at the origin.

Therefore, we conclude that If A (2, 3) maps to A' (4, 6) under a certain enlargement:

Step-by-step explanation:

We know that when any object is dilated by a certain scale factor, it gets reduced or enlarged. The reduction or enlargement depends upon the scale factor.

If the scale factor > 1, the image is an enlargement.

If the scale factor < 1, the image is reduced.

For example, if a point P(x, y) is dilated by a scale factor of 2 with a center at the origin, the image P' will have the coordinates (2x, 2y).

As scale factor 2 > 1, so the image P' is enlarged.

Given the point

A(2, 3)

Rule of dilation by a scale factor 2 with a center at the origin

P(x, y) → P'(2x, 2y)

A(2, 3) → A'(2(2), 2(3)) = A'(4, 6)

It is clear that image A' has the coordinates (4, 6). i.e. A'(4, 6).

In other words, the image A'(4, 6) is the result of dilation of the original point A(2, 3) by a scale factor 2 with a center at the origin.

Therefore, we conclude that If A (2, 3) maps to A' (4, 6) under a certain enlargement:

We can rewrite the given expression as follows:
$\sqrt{5} \frac{1}{\sqrt{5}} \sqrt{7} \frac{1}{\sqrt{7}} = \frac{\sqrt{5}}{\sqrt{5}} \cdot \frac{\sqrt{7}}{\sqrt{7}} = \frac{5}{\sqrt{5}\sqrt{5}} \cdot \frac{7}{\sqrt{7}\sqrt{7}}$

Now, we simplify further:
$= \frac{5}{5} \cdot \frac{7}{7} = \frac{1 \cdot 1}{1}$

So, in the form $\dfrac{a\sqrt{5}  b\sqrt{7}}{c}$, we have $a = 0$, $b = 0$, and $c = 1$. Therefore, the product $abc = 0 \cdot 0 \cdot 1 = 0$.

First, let's simplify the expression:
$\sqrt{5} \frac{1}{\sqrt{5}} \sqrt{7} \frac{1}{\sqrt{7}} = \frac{\sqrt{5}}{\sqrt{5}} \cdot \frac{\sqrt{7}}{\sqrt{7}} = 1$

So now we want to write $1$ in the form $\dfrac{a\sqrt{5}  b\sqrt{7}}{c}$ with positive integers $a$, $b$, and $c$, and $c$ as small as possible.

We can do this by setting $a=b=c=1$ since $1\cdot 1\cdot 1 = 1$ and $1$ is the smallest possible value for $c$. So we have:
$1 = \dfrac{1\sqrt{5}\cdot 1\sqrt{7}}{1}$

Therefore, $a=1$, $b=1$, and $c=1$, so $abc=1$.

For a uniformly distributed random variable, the correct statement is B: The probability distribution function is constant over the definition space.

A uniformly distributed random variable has a constant probability distribution function (PDF) over its definition space. This means that the probability of obtaining any value within the range of the variable is equal.

Statement A is incorrect because the expected value of a uniformly distributed random variable is not necessarily equal to 1. The expected value is calculated by taking the average of all possible values, and for a uniform distribution, it is equal to the average of the minimum and maximum values in the distribution.

Statement C is also incorrect because a uniformly distributed random variable does not have a probability density function (PDF) since it is a discrete distribution. Instead, it has a probability mass function (PMF), which assigns equal probabilities to each value in its definition space.

Statement D is incorrect because the probability density function (PDF) or probability mass function (PMF) of a uniformly distributed random variable takes on non-negative values since probabilities must be non-negative.

Therefore, the correct statement is B: The probability distribution function is constant over the definition space.

The sale price of the promissory note is approximately $5,354.29.

To calculate the sale price, we need to determine the present value of the remaining payments on the promissory note using the given discount rate of 10% compounded quarterly. The remaining term of the promissory note is 5 years - 2 years 3 months = 2 years 9 months = 2.75 years.

Using the formula for present value, we can calculate the sale price as follows:

Sale Price = Remaining Payments / (1 + Discount Rate/Number of Compounding Periods)^(Number of Compounding Periods * Remaining Time)

Remaining Payments = $7,200 (the face value of the promissory note)

Discount Rate = 10% / 4 = 0.025 (quarterly rate)

Number of Compounding Periods = 4 (quarterly compounding)

Remaining Time = 2.75 years

Plugging in the values, we have:

Sale Price = $7,200 / (1 + 0.025)^(4 * 2.75)

= $7,200 / (1.025)^11

≈ $5,354.29
