The distance between the points (-3, 2) and (2, -2) is approximately sqrt(41), which is an irrational number.

To find the distance between two points (-3, 2) and (2, -2), we can use the Pythagorean theorem and consider the points as the vertices of a right triangle.

The base of the triangle is the horizontal distance between the x-values of the two points.

In this case, it is given by:

Base = 2 - (-3) = 2 + 3 = 5

Next, we need to find the height of the triangle, which is the vertical distance between the y-values of the two points. It is given by:

Height = -2 - 2 = -4

Now, we have the base and the height of the triangle.

To find the distance between the two points, we can use the Pythagorean theorem, which states that the square of the hypotenuse (distance) is equal to the sum of the squares of the other two sides (base and height).

Using the Pythagorean theorem:

Distance^2 = Base^2 + Height^2

Distance^2 [tex]= 5^2 + (-4)^2[/tex]

Distance^2 = 25 + 16

Distance^2 = 41

To find the distance, we take the square root of both sides:

Distance = sqrt(41).

Step-by-step explanation:

Can you provide an image please?

Answer:

C

Step-by-step explanation:

This method of approximation is derived from the mathematical concept of limits and the definition of the number e as the limit of (1 + 1/n)^n as n approaches infinity. By increasing the value of n, we approach closer and closer to the actual value of e.

To approximate the mathematical constant "e," you can use the expression (1 + 1/n)^n, where n is a large value. As n approaches infinity, this expression converges to the value of e. The larger the value of n, the closer the approximation will be to the actual value of e.

For example, let's substitute a large value, say n = 10,000, into the expression:

Approximation of e ≈ (1 + 1/10,000)^10,000

Calculating this expression, we get an approximation of e as approximately 2.7181459. Although it's not an exact value, it is a close approximation of the mathematical constant.

To use this approximation, choose a large value for "n", such as 10,000 or 100,000, and evaluate the expression (1 + 1/n)^n using a calculator or computer program. The result will be a close approximation of the value of "e". The larger the value of "n", the more accurate the approximation will be.

The graph of the line y = 4x + 1 is on the graph at the end.

A linear equation in the slope-intercept form is written as:

Where a is the slope and b is the intercept of the y-axis.

Here we know that:

The triangle after the reflection over the line y = x has image points: (x'k), (5,-2), and (-6,-1). The corresponding preimage points are: (3,4), (4,3), and (-2,5).

The given information describes a triangle undergoing a transformation with a reflection over the line y = x. Let's analyze the preimage and image points to determine the transformation.

Preimage points: (3,4), (4,3), and (-2,5)

Image points: (x'k), (5,-2), and (-6,-1)

Since we know the reflection is over the line y = x, we can determine the image points by swapping the x and y coordinates of the preimage points. Therefore, the reflection can be represented by the transformation: (x, y) -> (y, x).

Applying this transformation to the preimage points, we get the image points as follows:

(3,4) -> (4,3)

(4,3) -> (3,4)

(-2,5) -> (5,-2)

Now we can check if the image points match the given image points:

(4,3) matches (x'k)

(3,4) matches (5,-2)

The factors of the original expression, u and v to produce a sum of simpler terms, the derivative of y with respect to x is: y' = -2x⁴ - x² - 10x + 15

Given the expression y = (3 - x²) (x³ - 5x + 5),

We need to find the derivative of y with respect to x.

We can find y' using two methods:

Method 1: Applying the Product RuleIf y = uv, then we know that y' = u'v + uv'Applying this formula to the given expression, We get:

y = (3 - x²) (x³ - 5x + 5)u = (3 - x²) and v = (x³ - 5x + 5)

Differentiating u and v, we get:u' = -2x and v' = 3x² - 5

Substituting these values into the formula for y', we get:

y' = u'v + uv' = (-2x) (x³ - 5x + 5) + (3 - x²) (3x² - 5)

Simplifying this expression, we get:

y' = -2x⁴ + 10x² - 10x - 3x² + 15 = -2x⁴ - x² - 10x + 15

Method 2: Multiplying the Factors to Produce a Sum of Simpler Terms to Differentiate

Expanding the given expression, we get:

y = 3x³ - 15x + 15 - x⁵ + 5x³ - 5x - 3x² + 15x² - 15x

Differentiating this expression, we get: y' = 9x² - 15 + 0 - 5x⁴ + 15x² - 5 - 6x + 30x - 15

Simplifying this expression, we get:

y' = -2x⁴ - x² - 10x + 15

Therefore, the derivative of y with respect to x is:y' = -2x⁴ - x² - 10x + 15

x | y

0 | 5

1 | 10

2 | 15

3 | 20

4 | 25

To fill in the table using the function rule y = 5 + 5x, we can substitute different values of x into the equation and calculate the corresponding values of y.

Let's create a table:

x | y

0 | 5 + 5(0) = 5 + 0 = 5

1 | 5 + 5(1) = 5 + 5 = 10

2 | 5 + 5(2) = 5 + 10 = 15

3 | 5 + 5(3) = 5 + 15 = 20

4 | 5 + 5(4) = 5 + 20 = 25

Using the function rule y = 5 + 5x, we can substitute each value of x into the equation to find the corresponding value of y. For example, when x = 0, y = 5. When x = 1, y = 10, and so on.

Therefore, the completed table is:

x | y

The correct Option is C. Dominic buys about 18 ounces of romaine lettuce in the 64-ounce container of salad mix.

From the pie chart, we can infer that the percentage of romaine lettuce in the salad mix is 27%.

We can find the number of ounces of romaine lettuce in a 64-ounce container of salad mix by multiplying 64 by 27/100.

This is because we want to find what fraction of the whole salad mix is romaine lettuce, and then multiply it by the total number of ounces in the container.

Using proportions, we can find that:Let x be the number of ounces of romaine lettuce in a 64-ounce container of salad mix.

27/100 = x/64

Solving for x, we get:x = (27/100) * 64 = 18.28

Therefore, there are about 18.28 ounces of romaine lettuce in a 64-ounce container of salad mix.

However, since we are asked to give an approximate answer, we can round this to the nearest whole number, which is 18.

So, Dominic buys about 18 ounces of romaine lettuce in the 64-ounce container of salad mix.

The width of the frame is 1 inch.

To determine the width of the frame, we must subtract the area of the picture from the total area.

Therefore: total area - picture area = frame area

261.44 - 168 = 93.44 square inches

The frame area can also be calculated by multiplying the frame width by 2 (since there are two sides of the frame) and adding it to the picture dimensions.

Thus:2w + 12 = length2w + 14 = width where w is the width of the frame.

Using the above equations, we can solve for w: 2w + 12 = 14, 2w = 2, and w = 1

Mill A and Mill B should be operated for 6 days each in order to meet the contract order most economically

Let's define the variables:

- Let 'x' represent the number of days mill A is operated per week.

- Let 'y' represent the number of days mill B is operated per week.

We need to minimize the cost function, which is the sum of the operating costs for both mills:

Cost = 1000x + 800y

Now, let's consider the production constraints:

For the HIGH grade flour:

Mill A produces 6 quintals per day, so the total weekly production is 6x.

Mill B produces 2 quintals per day, so the total weekly production is 2y.

To meet the contract requirement of 12 quintals per week, we have the constraint:

6x + 2y ≥ 12

For the MEDIUM grade flour:

Mill A produces 2 quintals per day, so the total weekly production is 2x.

Mill B produces 2 quintals per day, so the total weekly production is 2y.

To meet the contract requirement of 8 quintals per week, we have the constraint:

2x + 2y ≥ 8

For the LOW grade flour:

Mill A produces 4 quintals per day, so the total weekly production is 4x.

Mill B produces 12 quintals per day, so the total weekly production is 12y.

To meet the contract requirement of 24 quintals per week, we have the constraint:

4x + 12y ≥ 24

The graph will have the axes 'x' and 'y' representing the number of days mill A and mill B are operated, respectively.

Let's solve the problem graphically:

To plot each constraint, we can convert them into linear equations:

1) 6x + 2y ≥ 12

  Rewrite as: 3x + y ≥ 6

  Plot the line: 3x + y = 6

  From the graph, Mill A should be operated for 2 days per week while Mill B should be operated for 6 days per week.

2) 2x + 2y ≥ 8

  Rewrite as: x + y ≥ 4

  Plot the line: x + y = 4

  From the graph, Mill A should be operated for 4 days per week while Mill B should be operated for 4 days per week.

3) 4x + 12y ≥ 24

  Rewrite as: x + 3y ≥ 6

  Plot the line: x + 3y = 6
