The coordinates of point E is (-2, -1.5)

How to determine the coordinates of point E?

see in the file attached below

The given parameters are

C = (1, 6)

D = (-3, -4)

The ratio 3/4 can be represented as:

m : n = 3 : 1

So, the coordinate of point E is

E = 1/(m + n) * (mx2 + nx1, my2 + ny1)

So, we have:

E = 1/(3 + 1) * (3 * -3 + 1 * 1, 3 * -4 + 1 * 6)

Evaluate

E = 1/(4) * (-8, -6)

This gives

E = (-2, -1.5)

Hence, the coordinates of point E is (-2, -1.5 )

Answer:

  (d)  b/a

Step-by-step explanation:

The applicable rule of exponents is ...

  (a^b)/(a^c) = a^(b-c)

__

Then the expression simplifies to ...

  b^-2/(ab^-3) = b^(-2-(-3))/a = b^1/a = b/a

Answer: Choice B)  \(y \ge \frac{3}{4}x-3\)

The boundary is the equation y = (3/4)x-3 which goes through (0,-3) and (4,0)

This boundary is a solid line. Since it's a solid line, we will involve "or equal to" as part of the inequality sign.

The shading above the boundary line indicates we'll also have "greater than" as part of the inequality sign.

So overall, the inequality sign is "greater than or equal to". That leads to choice B.

The differences are not all equal, this sequence is not an Arithmetic sequence.

An arithmetic sequence refers to a sequence of numbers that have a common difference. This means that the numbers in the sequence increase or decrease by a fixed amount known as the common difference. An example of an arithmetic sequence is 2, 4, 6, 8, 10, and so on, where the common difference is 2.  Therefore, a sequence that has a common difference is an arithmetic sequence.
Here are some examples of sequences to determine if they are arithmetic:
1. 4, 9, 14, 19, 24, ...
To determine whether this is an arithmetic sequence, we need to find the common difference. We do this by subtracting each number from the one that follows it:
9 − 4 = 5
14 − 9 = 5
19 − 14 = 5
24 − 19 = 5
Since the differences are all equal to 5, this sequence is an arithmetic sequence with a common difference of 5.
2. 2, 5, 8, 11, 14, ...
To determine whether this is an arithmetic sequence, we need to find the common difference. We do this by subtracting each number from the one that follows it:
5 − 2 = 3
8 − 5 = 3
11 − 8 = 3
14 − 11 = 3
Since the differences are all equal to 3, this sequence is an arithmetic sequence with a common difference of 3.
3. 3, 6, 11, 18, 27, ..
To determine whether this is an arithmetic sequence, we need to find the common difference. We do this by subtracting each number from the one that follows it:
6 − 3 = 3
11 − 6 = 5
18 − 11 = 7
27 − 18 = 9
Since the differences are not all equal, this sequence is not an arithmetic sequence.

Friend functions may directly modify or access the private data members. group of answer choices are true.

A friend function in C++ is a function that is not a member of a class but has access to its private and protected members. It is declared with the keyword "friend" inside the class. One of the advantages of using friend functions is that they can directly modify or access the private data members of a class, bypassing the normal access restrictions.

Friend functions are able to do this because they are granted special privileges by the class they are declared in. This means that they can access private data members and even modify them without using the usual public member functions of the class.

This feature can be useful in certain scenarios. For example, if we have a class that represents a complex number, we may want to provide a friend function to calculate the magnitude of the complex number directly using its private data members, instead of going through a getter function..

In conclusion, friend functions in C++ can indeed directly modify or access private data members. While this can be a powerful tool in certain cases, it should be used with caution to maintain the integrity of the class's encapsulation.

Answer:

7 and 1/8 i think

Step-by-step explanation:

Equilibrium occurs when the forward and reverse reactions take place at a constant rate in a closed system at a constant temperature.

Equilibrium in a chemical reaction refers to a state where the forward and reverse reactions occur at the same rate, resulting in no net change in the concentrations of reactants and products over time. This state is achieved in a closed system, meaning no reactants or products can enter or leave the system during the reaction. Additionally, the system must be at a constant temperature for equilibrium to be reached.

At equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction. Initially, as the reactants undergo the forward reaction, the concentration of products increases while the concentration of reactants decreases. Simultaneously, as the products react in the reverse direction, the concentration of reactants increases while the concentration of products decreases. As the system progresses, the rates of both reactions gradually decrease until they reach a point where they are equal. This balanced state is called dynamic equilibrium, as the reactions continue to occur, but with no overall change in the concentration of species. It's important to note that while the concentrations remain constant at equilibrium, the reactions themselves do not stop; they are simply occurring at an equal rate.

The area of sector of the circle is approximately 471 cm².

To find the area of the sector of a circle, we need to use the formula:

Area of Sector = (Central Angle / 360) x πr²

Here, the central angle is 135º, and the radius of the circle is 20 cm.

So, substituting these values in the formula, we get:

Area of Sector = (135/360) x π x 20²
Area of Sector = (3/8) x π x 400
Area of Sector = 150π

Hence, the area of the sector is 150π cm².

However, since π is an irrational number, we need to approximate the value. Taking π ≈ 3.14, we get:

Area of Sector ≈ 150 x 3.14
Area of Sector ≈ 471 cm²

Therefore, the area of the sector is approximately 471 cm².

The probability of at least 2 people having the same birthday in a group of 23 people is 0.5073.

The probability of at least 2 people having the same birthday in a group of 23 people can be calculated using the rule for complements. The complement of this event is that all 23 people have different birthdays. We can calculate the probability of this event and then subtract it from 1 to find the probability of at least 2 people having the same birthday.

The probability of the first person having a different birthday from the others is 1. The probability of the second person having a different birthday from the first is 364/365, since there are 364 days left that are not the first person's birthday. The probability of the third person having a different birthday from the first two is 363/365, and so on.

The probability of all 23 people having different birthdays is:

1 * (364/365) * (363/365) * ... * (343/365)

This simplifies to:

364! / (36522 * 341!)

Using a calculator, we find that this is approximately 0.4927.

Therefore, the probability of at least 2 people having the same birthday is:

1 - 0.4927 = 0.5073

So, the probability of at least 2 people having the same birthday in a group of 23 people is 0.5073.

In a group of 23 persons, the probability that at least two of them share the same birthday is around 0.5073, or 50.73%.

The probability that at least 2 people in a group of 23 have the same birthday, can be calculated by using the rule for compliments. First, we can calculate the probability that no two people share a birthday in a group of  23.

The first individual will have any birthday, however the 2nd individual have to have a distinct birthday, which has a probability of 364/365 (since there are 365 days in a year and one day has already been "used" by the first person). The probability that the third individual will have a different birthdate from the previous two is 363/365. Continuing in this way,

The probability that all 23 people have different birthdays is:

(365/365) x (364/365) x (363/365) x ...

Since the probabilities of all conceivable outcomes must sum up to 1, subtract the likelihood that at least two persons will have the same birthdate from one:

P(at least 2 people have the same birthday) = 1 - (365/365) x (364/365) x (363/365) x ... x (344/365)

P(at least 2 people have the same birthday) = 0.5073

There are 28 choices for the representative and 27 choices for the alternate, for a total of 28 * 27 = 756 possible combinations of representative and alternate.

There are 28 students in Mr. Miller's homeroom, so there are 28 choices for the student council representative. For the alternate, there are 27 remaining students to choose from (since one student has already been chosen as the representative). Therefore, there are 28 choices for the representative and 27 choices for the alternate, for a total of 28 * 27 = 756 possible combinations of representative and alternate.

It is important to note that this is a combination, not a permutation, because the order in which the representative and alternate are chosen does not matter. If the order did matter, there would be a total of 28 * 27 = 756 * 2 = 1512 possible permutations.
