To find the image of point Q after applying the given translation rule, we need to apply the rule to the coordinates of point Q(-2, 6).

Using the translation rule (x, y) → (x + 4, y - 5), we can apply the rule to the coordinates of point Q:

Q' = (-2 + 4, 6 - 5)

= (2, 1)

Therefore, the image of point Q after the translation is Q'(2, 1).

Part: $1.92 (the discount amount)

Percent: 30% (the discount percentage)

Base: The original price of the item before the discount and sale, which we can calculate as follows:

Let x be the original price of the item.

The discount of $1.92 represents 30% of the original price, so we can write:

0.30x = 1.92

Solving for x, we get:

x = 1.92 / 0.30

x = 6.40

Therefore, the base is $6.40 (the original price of the item before the discount and sale).

The probability of winning the jackpot on one try is 1/30 or 0.0333 (rounded to four decimal places).

To calculate the probability of winning the jackpot on one try, we need to determine the number of favorable outcomes (winning combinations) and the total number of possible outcomes.

The number of favorable outcomes can be calculated by selecting 4 different numbers from 1 to 45 (without considering the order) and one number from 1 to 30. This can be represented as:

C(45, 4) * C(30, 1)

where C(n, r) represents the number of combinations of n items taken r at a time.

The total number of possible outcomes is the total number of ways to select 4 numbers from 1 to 45 (without considering order) multiplied by the number of ways to select one number from 1 to 30. This can be represented as:

C(45, 4) * 30

To calculate the probability, we divide the number of favorable outcomes by the total number of possible outcomes:

Probability = (C(45, 4) * C(30, 1)) / (C(45, 4) * 30)

Simplifying the expression:

Probability = C(30, 1) / 30

Probability = 1 / 30

Therefore, the probability of winning the jackpot on one try is 1/30 or 0.0333 (rounded to four decimal places).

Answer:

Since all three distances are equal to 2√3, we can conclude that the points 2, -1+i√3, -1-i√3 form an equilateral triangle on the Argand plane. This proves the statement.

Step-by-step explanation:

To prove that the points 2, -1+i√3, -1-i√3 form an equilateral triangle on the Argand plane, we need to show that each side of the triangle has the same length, which is equal to the distance between any two of the points.

Let's first find the distance between points 2 and -1+i√3. We can use the distance formula:

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

where (x₁, y₁) = (2, 0) and (x₂, y₂) = (-1, √3). Substituting in the values, we get:

d₁ = √[(-1 - 2)² + (√3 - 0)²] = √[9 + 3] = √12 = 2√3

Next, let's find the distance between points -1+i√3 and -1-i√3:

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

where (x₁, y₁) = (-1, √3) and (x₂, y₂) = (-1, -√3). Substituting in the values, we get:

d₂ = √[(-1 - (-1))² + (-√3 - √3)²] = √[0 + 12] = 2√3

Finally, let's find the distance between points -1-i√3 and 2:

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

where (x₁, y₁) = (-1, -√3) and (x₂, y₂) = (2, 0). Substituting in the values, we get:

d₃ = √[(2 - (-1))² + (0 - (-√3))²] = √[9 + 3] = √12 = 2√3

Since all three distances are equal to 2√3, we can conclude that the points 2, -1+i√3, -1-i√3 form an equilateral triangle on the Argand plane. This proves the statement.

The correct sum of numbers from 1 to n is 100.

We have,

Let's assume the correct sum of numbers from 1 to n is S.

According to the problem,

Juan made a mistake and added one of the numbers twice.

Let's call this number x.

The wrong sum that Juan obtained is 100.

The correct sum, S, can be expressed as the sum of numbers from 1 to n excluding the number x, plus the number x itself:

S = (1 + 2 + 3 + ... + (x-1) + (x+1) + ... + n) + x.

Since Juan added x twice, the wrong sum can be expressed as the sum of numbers from 1 to n without excluding any number: 100 = 1 + 2 + 3 + ... + (x-1) + x + (x+1) + ... + n.

We can subtract the correct sum equation (step 4) from the wrong sum equation (step 5) to find the value of x:

100 - S = (1 + 2 + 3 + ... + (x-1) + x + (x+1) + ... + n) - ((1 + 2 + 3 + ... + (x-1) + (x+1) + ... + n) + x).

Simplifying further, we get: 100 - S = x - x = 0.

From step 6, we see that 100 - S = 0, which means S = 100.

Therefore,

The correct sum of numbers from 1 to n is 100.

In conclusion, the correct sum of the numbers from 1 to n is 100.

Adding the two cases together, we get a total of 360 + 720 = 1080 six-digit numbers that can be formed using the digits 1, 2, 3, 4, 5, and 6 once, such that the number is divisible by its unit digit.

To find the number of 6-digit numbers that can be formed using the digits 1, 2, 3, 4, 5, and 6 once, such that the 6-digit number is divisible by its unit digit, we can consider the following cases:

Case 1: The unit digit is 2, 4, or 6

In this case, the unit digit is already divisible by itself. We have 3 choices for the unit digit. For the remaining 5 digits, we have 5 choices for the first digit, 4 choices for the second digit, 3 choices for the third digit, 2 choices for the fourth digit, and 1 choice for the fifth digit. Therefore, the total number of 6-digit numbers is 3 * 5 * 4 * 3 * 2 * 1 = 360.

Case 2: The unit digit is 1, 3, or 5

In this case, the unit digit is not divisible by itself. We have 3 choices for the unit digit. For the remaining 5 digits, we have 5 choices for the first digit, 4 choices for the second digit, 3 choices for the third digit, 2 choices for the fourth digit, and 1 choice for the fifth digit. However, for the sixth digit, it cannot be the same as the unit digit since the number needs to be divisible by the unit digit. Therefore, we have 2 choices for the sixth digit. Hence, the total number of 6-digit numbers is 3 * 5 * 4 * 3 * 2 * 2 = 720.

Adding the two cases together, we get a total of 360 + 720 = 1080 six-digit numbers that can be formed using the digits 1, 2, 3, 4, 5, and 6 once, such that the number is divisible by its unit digit.\

Step-by-step explanation:

Multiplying 0.79 by √2 yields an irrational answer.

To determine which number produces an irrational answer when multiplied by 0.79, we need to identify a number that, when multiplied by 0.79, results in a non-terminating and non-repeating decimal.

If the result of multiplying a number by 0.79 is a rational number, it would have a terminating or repeating decimal representation. However, if the result is an irrational number, it would have a non-repeating and non-terminating decimal representation.

To find such a number, we can look for an irrational number, such as the square root of a non-perfect square. Let's consider √2.

When we multiply 0.79 by √2, the result is:

0.79 * √2 ≈ 1.1141...

The decimal representation of this product does not terminate or repeat, indicating that it is an irrational number. Therefore, multiplying 0.79 by √2 produces an irrational answer.

In summary, multiplying 0.79 by √2 yields an irrational answer.

To find a pair of values that make the linear equation 14x - y = -14 a true statement, we can choose any value for x and calculate the corresponding value of y.

Let's choose x = 2:

14(2) - y = -14

28 - y = -14

Now, we can solve for y:

-y = -14 - 28

-y = -42

Dividing both sides by -1 (to isolate y):

y = 42

Therefore, the pair of values (x, y) that make the equation true is (2, 42).

Step-by-step explanation:

If the company has budgeted 6 2/3 hours to complete a project, and 1/4 of that time is spent on research, we can find the amount of time spent on research as follows:

Total time for the project = 6 2/3 hours

Time spent on research = (1/4) * (6 2/3) hours

We can simplify 6 2/3 to an improper fraction as follows:

6 2/3 = (6 x 3 + 2) / 3 = 20/3

Substituting this value into the equation above, we get:

Time spent on research = (1/4) * (20/3) hours

Multiplying the fractions, we get:

Time spent on research = 5/3 hours

We can convert this improper fraction to a mixed number as follows:

5/3 = 1 2/3

Therefore, the company plans to spend 1 2/3 hours on research.

If the typical duration for a customer to receive their food in a dining establishment is 15 minutes, it is possible to utilize the exponential function to estimate the likelihood of obtaining the meal within the initial 10 minutes.

The probability density function (PDF) that characterizes the exponential distribution is expressed as f(x) = (1/µ) * e^(-x/µ), where µ denotes the mean or average value.

The average duration in this scenario is 15 minutes, denoted as µ. Our goal is to determine the probability of X falling between the limits of a and b, where a is set at 0 and b is set at 10.

To calculate this probability, we need to integrate the PDF from a to b:

P(0 ≤ X ≤ 10) = ∫[tex][0 to 10] (1/15) * e^(-x/15) dx[/tex]

Integrating this expression gives us:

P(0 ≤ X ≤ 10) = [tex][-e^(-x/15)] from 0 to 10[/tex]

To rewrite equation [tex]x^2 + 5x + 6[/tex] as[tex]x^2 + rx + sx + 6[/tex], we need to choose suitable values for r and s that satisfy r + s = 5.

To rewrite the quadratic expression[tex]x^2 + 5x + 6[/tex] as equivalent to[tex]x^2 + rx + sx + 6[/tex] , we need to find the values of r and s that satisfy the equation.

Let's start by expanding [tex]x^2 + rx + sx + 6:[/tex]

[tex]x^2 + rx + sx + 6 = x^2 + (r + s)x + 6[/tex]

We can see that the coefficient of x in the original expression is 5, and in the rewritten expression, it is (r + s). Therefore, we want to find values for r and s such that r + s = 5.

Next, we need to consider the constant term. In the original expression, the constant term is 6, and in the rewritten expression, it is also 6. Therefore, we want r, s, and 6 to satisfy the equation.

Since r + s = 5, we can solve for one variable in terms of the other. For example, if we choose r = 3, then s = 2 to satisfy the equation. Alternatively, we could choose r = 4 and s = 1, or any other combination that adds up to 5.

So, rewriting [tex]x^2 + 5x + 6[/tex] as [tex]x^2 + rx + sx + 6[/tex]can be achieved by choosing suitable values for r and s that satisfy r + s = 5.

For example, if we choose r = 3 and s = 2, the equivalent expression would be [tex]x^2 + 3x + 2x + 6.[/tex]

In summary, to rewrite[tex]x^2 + 5x + 6[/tex]as [tex]x^2 + rx + sx + 6[/tex], we need to choose suitable values for r and s that satisfy r + s = 5.
