The image of vertex Z after a 90 degree counterclockwise rotation about the origin is (-34, -1). To find the coordinates of the image points for X and Y, we would need to know their coordinates as well.

Although the question is a little challenging to understand as worded, I'll do my best to respond.

Here is what I believe you are asking, assuming "verticals eggs" is a typo and you meant "vertex angles" and "Z bar" is a typo and you meant "Z = (-1, 34)":

Triangle XYZ has vertex angles at X and Y and vertices at X, Y, and Z. Pointed at is Vertex Z (-1, 34). What are the coordinates of the picture points for the triangle XYZ if the triangle is rotated 90 degrees anticlockwise about the origin?

We can use the following rotation matrix to rotate the origin 90 degrees anticlockwise:

R = [sin(90); cos(90); cos(90)-cos(90)]

R = [0 -1; 1 0]

We may represent the coordinates of each point in the triangle as a column vector and then multiply by the rotation matrix to apply this matrix to each point in the triangle:

[X'; Y'] = R * [X; Y]

[Z'] = R * [Z; 1]

(Notice that we make the Z coordinate a homogeneous coordinate by adding a third component of 1 to it.)

We are unable to provide the precise coordinates of the image points without knowing the X and Y coordinates. However, we can multiply matrices using the Z coordinate that is provided:

[Z'] = R * [-1; 34; 1]

[Z'] = [(-1) * 0 + 34 * (-1) + 1 * 0; (-1) * 1 + 34 * 0 + 1 * 0; (-1) * 0 + 34 * 0 + 1 * 1]

[Z'] = [-34; -1; 1]

Hence, vertex Z's image following a 90° anticlockwise rotation of the origin is (-34, -1). We would also need to know their coordinates in order to determine the coordinates of the image points for X and Y.

Answer:

supplementary: 1 and 2, as they add to 180

vertical: 2 and 3, as they are opposite and equal each other.

Answer:

Step-by-step explanation:

Supplementary angles are 2 angles that add up to 180 degrees, and vertical angles are angles opposite to each other. So for supplementary, we can have 1-2,3-4,5-6,7-8,1-3,2-4,5-7,6-8.

And for vertical, there can be 5-8,6-7,1-4 and 2-3

The value of the interquartile range for the given subsample is 8.

The interquartile range (IQR) is a measure of the dispersion of a set of observations. It is defined as the difference between the third quartile and the first quartile (Q3-Q1). The subsample data is as follows: 24, 27, 35, 31, 21, 22, 28, 18, 25, 24, 36, 20. The interquartile range for the subsample data can be computed as follows:

Step 1: Arrange the data in ascending order: 18, 20, 21, 22, 24, 24, 25, 27, 28, 31, 35, 36.

Step 2: Find the median of the lower half of the data, which is called the first quartile, Q1. Here, the lower half of the data is 18, 20, 21, 22, 24, and 24. Hence, the median of the lower half of the data is the average of the two middle values, which is Q1 = (22 + 21)/2 = 21.5.

Step 3: Find the median of the upper half of the data, which is called the third quartile, Q3. Here, the upper half of the data is 24, 25, 27, 28, 31, 35, and 36. Hence, the median of the upper half of the data is the average of the two middle values, which is Q3 = (28 + 31)/2 = 29.5.

Step 4: Calculate the interquartile range as the difference between the third quartile and the first quartile: IQR = Q3 - Q1 = 29.5 - 21.5 = 8.

Therefore, the value of the interquartile range for the given subsample is 8.

Variables:

A variable is a characteristic of an object. Their values may occur more than once for a set of data. We consider just two main types of variables in this course.

Quantitative Variables - Variables whose values result from counting or measuring something.

Qualitative Variables - Variables that are not measurement variables. Their values do not result from measuring or counting.

Given,

A pharmaceutical company conducts an experiment in which a subject takes 75 mg of a substance orally.

And  the researchers measure how many seconds it takes for one quarter of the substance to exit the bloodstream.

An integer is divisible by 9 if and only if the sum of its decimal digits is divisible by 9, can be proved by using congruent module system.

Let us first prove that if the sum of the digits of a number is divisible by 9, then the number is divisible by 9.

Let n be a positive integer and let a₀,a₁,a₂,....,ak be its decimal digits.

We know that any positive integer n can be expressed in the following form:

n = a₀ + 10a₁ + 100a₂ + ... + ak * 10k

Notice that each power of 10 is congruent to 1 modulo 9.

Therefore, we have:

n ≡ a₀ + a₁ + a₂ + ... + ak (mod 9)

If the sum of the digits of n is divisible by 9, then n ≡ 0 (mod 9).

This implies that n is divisible by 9.Now, let us prove that if a number is divisible by 9, then the sum of its digits is divisible by 9.

Let n be a positive integer that is divisible by 9. We can write n in the following form:n = a0 + 10a1 + 100a2 + ... + ak * 10k

Since n is divisible by 9, it follows that:n ≡ a₀ + a₁ + a₂ + ... + ak (mod 9)

Because each power of 10 is congruent to 1 modulo 9, we have:

n ≡ a₀ + a₁ + a₂ + ... + ak (mod 9)≡ a0 + 10a1 + 100a₂ + ... + ak * 10k (mod 9)≡ n (mod 9)

This implies that n ≡ 0 (mod 9), which means that the sum of the digits of n is divisible by 9.

The tangential and normal components of the acceleration when s = 10 m is 40 m/s^2 and 8 m/s^2 respectively.

In the given question, a car is travelling along the road with a speed of 2s m/s, where s is in meters.

We have to determine the tangential and normal components of the acceleration when s = 10 m.

Speed (v) = 2s  

Motion is circular so, Radius of circle = 50m

Tangential acceleration = dv/dt

Tangential acceleration = d(2s) / dt

Tangential acceleration = 2(ds)/dt

Tangential acceleration = 2v

Tangential acceleration = 2(2s)

Tangential Acceleration = 4s

As given s = 10 m

Tangential acceleration = 4 x 10

Tangential acceleration  = 40 m/s^2

Normal acceleration = v^2/ r

Normal acceleration = 4s^2/r

Normal acceleration = {4 x 10^2}/50

Normal acceleration = {4 x 100}/50

Normal acceleration = 400/50

Normal acceleration = 8 m/s^2

Answer:

y=2x-8

Step-by-step explanation:

To write the equation in slope intercept form y=mx+b you need a slope and the y-intercept. We will calculate the slope and then substitute it and a point into the point slope form . Simplifying this form y-y1=m (x-x1) will result in slope intercept form.

Calculate the slope by subtracting the y values and x values of the points.

m= 6-0/7-4= 6/3=2

The slope is 2. Choose one point to use the slope with in the point slope form. Then substitute and simplify.

y-0=2(x-4)

A ratio obtained by multiplying or dividing the numerator and denominator of a given ratio by the same number is called an equivalent ratios.

Hope this helps you ;]

Step-by-step explanation:

Answer:

7 - 2m can be translated to "7 minus two times m" or "the difference between 7 and twice m".

3(m + 2) = 15 can be translated to "three times the sum of m and 2 is equal to 15" or "the product of 3 and the sum of m and 2 is 15".

To solve the equation, we can start by distributing the 3 on the left side:

3(m + 2) = 15

3m + 6 = 15

Then, we can subtract 6 from both sides:

3m + 6 - 6 = 15 - 6

3m = 9

Finally, we can divide both sides by 3:

3m/3 = 9/3

m = 3

Therefore, the solution to the equation 3(m + 2) = 15 is m = 3.

5m - m(2 - m) can be translated to "5m minus the product of m and the difference between 2 and m" or "the difference between 5m and m times the quantity 2 minus m".

To simplify the expression, we can use the distributive property to expand the second term:

5m - m(2 - m) = 5m - 2m + m^2 = m^2 + 3m

Therefore, the simplified expression is m^2 + 3m.
