Therefore , the solution of the given problem of coordinates comes out to be B' = (-2, 1)  and  C' = (4, 6) .

A coordinate system is a method that employs one or more values or coordinates to accurately locate points or even other mathematical objects on a space, such as Euclidean space. Coordinates, that are pairs of numbers, are used to locate a point or object on a double plane. The y and x vectors are two integers that specify where a point is situated on a two - dimensional plane. a group of numerals designating particular places. Usually, the number has two numbers.

Here,

By adding 1 to the x-coordinate and 3 to the y-coordinate, we can determine that position A is translated to point A'. As a result, we can determine the values of B' and C' using the same translation vector.

We increase the x-coordinate for position B by one

=> (-3 + 1 = -2) and

the y-coordinate by three

=> (-2 + 3 = 1). Consequently, B"s values are (-2, 1).

We increase the x-coordinate for position C by one

=> (3 + 1 = 4) and

the y-coordinate by three

=>(3 + 3 = 6). Consequently, C"s dimensions are (4, 6).

Consequently, the translated locations' coordinates are as follows:

Answer:

Let's start by defining some variables to represent the given information:

T0 = 48°F (the current temperature)

deltaT = -1.5°F/hour (the rate of change in temperature)

T = 36°F (the target temperature)

We want to find how many hours it will take for the temperature to drop from 48°F to 36°F, so let's call that time h. We can use the formula for the linear relationship between temperature and time:

T = T0 + deltaT * h

We want to solve for h when T = 36°F, so we can substitute the given values and solve for h:

36 = 48 + (-1.5) * h

-12 = -1.5h

h = 8

Therefore, it will take 8 hours for the temperature to drop from 48°F to 36°F, assuming the temperature continues to decrease at a rate of 1.5°F per hour.

The probability of rolling a sum of 5 when rolling a 6-sided die twice is 1/9.

According to the Law of Large Numbers, a fundamental tenet of probability theory, the average of the results of an experiment approaches the predicted value of the random variable being measured as the number of trials in the experiment rises. In other words, the Law of Big Numbers states that the observed results will be closer to the predicted outcomes the more times an experiment is conducted.

The total number of outcomes when a die is rolled two times is 36.

The sum of 5 is obtained for the following outcomes:

(1,4), (2,3), (3,2), and (4,1)

Thus,

P(sum of 5) = 4/36 = 1/9

Answer:

If repetition of letter A is allowed and letter B cannot be repeated, then there are two cases to consider when constructing a 3-digit number:

Case 1: The first digit is letter A. In this case, there are 6 options for the first digit (since any of the 6 digits can be used), and there are 5 options for each of the remaining digits (since letter B cannot be repeated). Therefore, the total number of 3-digit numbers that can be formed in this case is:

6 x 5 x 5 = 150

Case 2: The first digit is not letter A. In this case, there are 5 options for the first digit (since letter A cannot be repeated), and there are 5 options for each of the remaining digits (since letter B cannot be repeated). Therefore, the total number of 3-digit numbers that can be formed in this case is:

5 x 5 x 4 = 100

To get the total number of 3-digit numbers that can be made from 1, 2, 3, 4, 5, and 6 with letter A repetition allowed and letter B repetition not allowed, we add the number of possibilities from Case 1 and Case 2:

Total = 150 + 100 = 250

Therefore, there are 250 different 3-digit numbers that can be made from 1, 2, 3, 4, 5, and 6 with letter A repetition allowed and letter B repetition not allowed.

There are 720 numbers consisting of 3 digits that can be made from 1, 2, 3, 4, 5, and 6 if letter A repetition is allowed and letter B repetition is not allowed.

This can be calculated by taking the number of possible combinations for each digit (6 for A, 5 for B, 4 for C) and multiplying them together: 6 x 5 x 4 = 120. Since there are 6 possible numbers for each digit, there are 120 combinations for a 3-digit number. Then, multiplying 120 by 6 (since repetition is allowed) yields 720 possible 3-digit numbers.

For the given arithmetic series, a_(1) = 27, d = 4, a_(n) = 783, n = 190, and n^(2) = 36100.

The given arithmetic series is 27, 31, 35,..., 783.

To find the first term, a_(1), we can simply look at the first term in the series. Therefore, a_(1) = 27.

To find the common difference, d, we can subtract the first term from the second term, or the second term from the third term. Therefore, d = 31 - 27 = 4.

To find the nth term, a_(n), we can use the formula a_(n) = a_(1) + (n - 1)d. We know that a_(1) = 27, d = 4, and a_(n) = 783, so we can plug these values into the formula and solve for n:

783 = 27 + (n - 1)(4)

756 = (n - 1)(4)

189 = n - 1

n = 190

Therefore, the nth term is 190.

To find the value of n^(2), we can simply square the value of n:

n^(2) = 190^(2) = 36100

Therefore, the value of n^(2) is 36100.

The wind generator will produce 2744W of power in a 35mph wind.

To find the power generated by the wind generator in a 35mph wind, we can use the formula P = kV³, where P is the power generated, k is a constant, and V is the wind's speed.

First, we need to find the value of k. We can do this by plugging in the given values of P and V into the formula and solving for k:

1000W = k(25mph)³ 1000W = k(15625mph³)

k = 1000W/15625mph³

k = 0.064W/mph³

Now that we have the value of k, we can plug it back into the formula along with the new wind speed of 35mph to find the power generated:

P = (0.064W/mph³)(35mph)³

P = (0.064W/mph³)(42875mph³)

P = 2744W

The model for the BMI of a person is:
BMI = (152100/weight in pounds)/(height in inches)^2

The Body Mass Index (BMI) of a person can be calculated using the formula:
BMI = (weight in pounds)/(height in inches)^2

In this case, the BMI varies directly as a person's weight in pounds and inversely as the square of the person's height in inches. This means that as the weight increases, the BMI increases and as the height increases, the BMI decreases.

To find a model for the BMI of a person, we can use the formula:
BMI = k(weight in pounds)/(height in inches)^2

Where k is a constant of proportionality. To find the value of k, we can use the given information that a 6ft 6in tall person has a BMI of 25.

First, we need to convert the height from feet and inches to inches. 6ft 6in is equivalent to 78 inches. Then, we can plug in the values into the formula and solve for k:

25 = k(weight in pounds)/(78 inches)^2
25(78 inches)^2 = k(weight in pounds)
152100 = k(weight in pounds)

Therefore, the model for the BMI of a person is:
BMI = (152100/weight in pounds)/(height in inches)^2

This model can be used to calculate the BMI of a person given their weight in pounds and height in inches.

The sides of the triangle circumscribed about a circle of radius 4 and divided on one side by the circle into segments of length 6 and 8 are 6, 8, and 4.

The triangle circumscribed about a circle of radius 4 and divided on one side by the circle into segments of length 6 and 8 can be found using the Law of Cosines. The Law of Cosines states that c2 = a2 + b2 - 2ab cos C, where c is the length of the hypotenuse, a and b are the lengths of the other sides, and C is the angle opposite side c.

We know the hypotenuse of this triangle is 8, as it is the length of one of the segments on the side of the triangle. We also know that angle C is 90° as it is a right triangle.

Therefore, using the Law of Cosines we can find the length of the other side of the triangle, which is 6. The equation is 82 = 62 + a2 - 2(6)(a)cos(90°). Solving this equation, we find that a = 4.

Therefore, the sides of the triangle circumscribed about a circle of radius 4 and divided on one side by the circle into segments of length 6 and 8 are 6, 8, and 4.

The standard form for the quadratic equation written in vertex form y = 2(x - 2)² + 5 is y = 2x² - 8x + 13.

What is a quadratic function?

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree.

To change the equation y = 2(x - 2)² + 5 from vertex form to standard form, we need to expand the squared term and simplify the expression.

Here are the steps -

Start with the vertex form: y = 2(x - 2)² + 5.

Expand the squared term using the formula (a - b)² = a² - 2ab + b².

In this case, a = x and b = 2, so we have -

y = 2(x - 2)(x - 2) + 5

y = 2(x² - 4x + 4) + 5

Multiply the coefficient 2 by each term inside the parentheses -

y = 2x² - 8x + 8 + 5

Combine the constant terms -

y = 2x² - 8x + 13

This is the standard form of the quadratic equation.

In standard form, the quadratic equation is written as y = ax² + bx + c, where a, b, and c are constants.

In this case, a = 2, b = -8, and c = 13.

Therefore, the standard form is y = 2x² - 8x + 13.

  3-4-5 right triangle is scalene

Step-by-step explanation:

You want to show the triangle defined by points P(3,2),Q(6,2) and R(6,6) is a scalene triangle.

We observe that points P and Q have the same y-coordinate, so lie on the horizontal line y=2. The length PQ is 6 -3 = 3 units.

Points Q and R have the same x-coordinate, so lie on the vertical line x=6. The length QR is 6 -2 = 4 units.

These legs are different lengths and are at right angles to each other. The third leg, the hypotenuse, will be longer than either of them.

The triangle's sides are unequal, so the triangle is a scalene triangle.
