The coordinates of A' and B' include the following:

A' (4, 7).

B' (10, 9).

In Mathematics and Geometry, a dilation is a type of transformation which typically changes the size of a geometric object, but not its shape.

Next, we would have to dilate the coordinates of the preimage by using a scale factor of 2 centered at the point (6, 3) by using the following mathematical expression:

(x, y)  →  (k(x - a) + a, k(y - b) + b)

For coordinate A', we have;

Coordinate A' = (5, 5)  →  (2(5 - 6) + 6, 2(5 - 3) + 3)

Coordinate A' = (5, 5)  →  (2(-1) + 6, 2(2) + 3)

Coordinate A' = (5, 5)  →  (-2 + 6, 4 + 3)

Coordinate A' = (5, 5)  →  (4, 7)

For coordinate B', we have;

Coordinate B' = (8, 6)  →  (2(8 - 6) + 6, 2(6 - 3) + 3)

Answer: The correct answer is B

Step-by-step explanation:

The point (2, -2) satisfies the blue inequality but not the red inequality. Explanation: To solve this system of inequalities, we need to check if the point (2, -2) is a solution to both of the inequalities. The blue inequality is y > 2x - 6. Plugging in the values of x = 2 and y = -2 gives:-2 > 2(2) - 6 => -2 > -2This is true, so the point (2, -2) satisfies the blue inequality. The red inequality is y < 1/2x + 1. Plugging in the values of x = 2 and y = -2 gives: -2 < 1/2(2) + 1 => -2 < 2This is false, so the point (2, -2) does not satisfy the red inequality. Therefore, the correct answer is B. The point (2, -2) satisfies the blue inequality but not the red inequality.

Therefore, if the time is between 8:00 a.m. and 3:00 p.m., then people may make withdrawals or deposits at the bank.

This conclusion is based on the given premises that the bank is open during the time between 8:00 a.m. and 3:00 p.m. and that when the bank is open, people may make withdrawals or deposits. By combining these premises with modus ponens (a valid form of deductive reasoning), we can infer that if the time is within the bank's operating hours, then people may make withdrawals or deposits at the bank.

The expression that does NOT represent 9+9+9+9+9+9+9 is 9 x 7.

The given expression 9+9+9+9+9+9+9 can be simplified by adding all the numbers together:

9+9+9+9+9+9+9 = 63

Therefore, the expression 63 represents 9+9+9+9+9+9+9.

However, if we multiply 9 by 7, we get:

9 x 7 = 63

Therefore, 9 x 7 represents the product of 9 and 7, not the sum of seven nines.

Step-by-step explanation:

To calculate your monthly take-home pay, you can use the following formula:

```

Monthly take-home pay = (Regular hourly rate x 40 hours x 5 days) + (Regular hourly rate x 8 hours x 2 Saturdays x 4 weeks) x 2 - Deductions

```

Where:

- Regular hourly rate = $15.20

- Deductions = 29% of gross pay

First, let's calculate the gross pay for one month:

```

Gross pay = (Regular hourly rate x 40 hours x 5 days) + (Regular hourly rate x 8 hours x 2 Saturdays x 4 weeks) x 2

= ($15.20 x 40 x 5) + ($15.20 x 8 x 2 x 4) x 2

= $3,424

```

Next, let's calculate the deductions:

```

Deductions = Gross pay x 29%

= $3,424 x 0.29

= $992.96

```

Finally, let's calculate the monthly take-home pay:

```

Monthly take-home pay = Gross pay - Deductions

= $3,424 - $992.96

= $2,431.04

```

Therefore, your monthly take-home pay is **$2,431.04**.

It will take the ball 2.12s to the nearest hundredth to hit the ground.

Quadratic formula is a formula that gives the solutions of the general quadratic equation ax² + bx + c = 0 and that is usually written in the form

x = (-b ± √(b2 − 4ac))/(2a)

From the question, the initial height, h, of the ball is 40 ft

When the ball hits the ground, the height, h, is zero

The equation h = - 16t² + 15t + 40 becomes

0 = - 16t² + 15t + 40

16t² - 15t - 40 = 0

Solving the quadratic equation by formula method for t,

t = (-b ± √(b² - 4ac)) / (2a)

Where, a = 16, b = -15, and c = -49

Substitute these values into the quadratic formula,

t = (15 ± √2785) / 32

Therefore, the possible values of t are:

t = (15 + √2785) / 32

t = (15 - √2785) / 32

Which implies t = 2.12 or t = - 1.18

Since time, t, cannot be negative, t = 2.12s to the nearest hundredth.

Picture it like this! Imagine you're running an extraordinary and magical Soup Express, a unique train that only serves delicious soup. Now, this peculiar train only has 144 seats available for each journey, and the moment has come when a bustling crowd of 1990 hungry passengers are waiting eagerly at the platform to board the Soup Express.

So, how many trips must your Soup Express make to serve all the soup-loving travelers?

To find that out, you'll divide the total number of passengers by the number of seats available on your train. That's 1990 passengers divided by 144 seats, which gives you about 13.82 trips. But, oh, the Soup Express can't very well make .82 of a trip, now can it? Your train must make full trips! So, you'll need to round up because even if there is just one passenger left, your train must still make the journey.

So, it turns out your Soup Express will need to make 14 full trips!

Now, let's find out how many passengers will be riding the final journey of the Soup Express. It's like having the leftovers after a grand feast! You've already served 13 full train journeys, each carrying 144 passengers. That's 13 journeys times 144 passengers, which equals 1872 satisfied soup enthusiasts!

But remember, you started with 1990 hungry passengers. So, to find out how many are left for the final trip, subtract the number of passengers already served from the total. That's 1990 minus 1872, which equals 118 passengers.

So, there you have it! The Soup Express will make 14 marvelous soup-serving trips, and the final journey will have 118 content passengers sipping on their favorite soup as they ride off into the sunset!

The line passing through p₁ and q₁ is parallel to the line passing through p₂ and q₂.

(a) To find the center and radius of a circle with the equation x² + y² + 2x + 8y = 8, we need to rewrite the equation in the standard form of a circle, which is (x - h)² + (y - k)² = r², where (h, k) represents the center of the circle and r represents the radius.

We start by completing the square for both x and y terms:

x² + 2x + y² + 8y = 8

(x² + 2x) + (y² + 8y) = 8

To complete the square for x terms, we add (2/2)² = 1 to both sides inside the parentheses:

(x² + 2x + 1) + (y² + 8y) = 8 + 1

(x + 1)² + (y² + 8y) = 9

To complete the square for y terms, we add (8/2)² = 16 to both sides inside the parentheses:

(x + 1)² + (y² + 8y + 16) = 9 + 16

(x + 1)² + (y + 4)² = 25

Now the equation is in the standard form. We can see that the center of the circle is (-1, -4) and the radius is the square root of 25, which is 5. Therefore, the center of the circle is (-1, -4) and the radius is 5.

(b) To show that the line through p₁(3, -4) and q₁(-2, 6) is parallel to the line through p₂(-3, 6) and q₂(9, -18), we need to demonstrate that the slopes of the two lines are equal.

The slope of the line passing through p₁ and q₁ is given by:

m₁ = (y₂ - y₁) / (x₂ - x₁)

  = (6 - (-4)) / (-2 - 3)

  = 10 / -5

  = -2

The slope of the line passing through p₂ and q₂ is given by:

m₂ = (y₂ - y₁) / (x₂ - x₁)

  = (-18 - 6) / (9 - (-3))

  = -24 / 12

  = -2

We can see that both slopes are equal to -2. Therefore, the line passing through p₁ and q₁ is parallel to the line passing through p₂ and q₂.

By demonstrating that the slopes of the two lines are equal, we have shown that the line through p₁(3, -4) and q₁(-2, 6) is parallel to the line through p₂(-3, 6) and q₂(9, -18).

The probability that six or fewer individuals will cover their mouth when sneezing is approximately 0.597.

To calculate the probabilities, we can use the binomial probability formula:

P(X = k) = [tex]C(n, k) * p^k * (1 - p)^{(n - k)}[/tex]

Given:

p = 0.29 (probability of an individual covering their mouth)

n = 10 (number of individuals observed)

(a) The probability that five individuals will cover their mouth when sneezing:

P(X = 5) = C(10, 5) * 0.29^5 * (1 - 0.29)^(10 - 5)

Calculating:

P(X = 5) = 0.0001677

Therefore, the probability that five individuals will cover their mouth when sneezing is approximately 0.0002.

(b) The probability that six or fewer individuals will cover their mouth when sneezing:

P(X ≤ 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6)

Calculating each individual probability and summing them up:

P(X ≤ 6) = 0.0075 + 0.043 + 0.1133 + 0.1954 + 0.2383 + 0.0002 + 0.000007

P(X ≤ 6) = 0.597

The slope of the graph is equal to 1 for all x between x= 0 and x=3.

Starting at x=3 the function value y increases as x increases.

The slope of the graph is equal to 3 for x between x=3 and x=5

For x between x=0 and x=4, the function value of y is ≤ 0.

For x between x=4 and x=8 the function of value y is ≥ 0.

In Mathematics and Geometry, the slope of any straight line can be determined by using the following mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = rise/run

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

By substituting the given data points into the formula for the slope of a line, we have the following;

Slope (m) = (0 - 3)/(3 - 0)

Slope (m) = -3/3

Slope (m) = -1.

For x between x=3 and x=5, the slope is given by;

Slope (m) = (3 + 3)/(5 - 3)

Slope (m) = 6/2

Slope (m) = 3.

By critically observing the graph of this function, we can logically deduce that the function value of y is less than or equal to 0 for x between x=0 and x=4 and greater than or equal to 0 for x between x=4 and x=8.

If the biased dice is rolled 150 times, we can expect to get approximately 45 ones

If the chance of getting a 1 on a biased dice is 0.3, it means that the probability of rolling a 1 on any given roll is 0.3 or 30%.

To determine how many ones you would get if rolled 150 times, we can multiply the probability of rolling a 1 (0.3) by the total number of rolls (150).

Number of ones = Probability of getting a 1 * Total number of rolls

Number of ones = 0.3 * 150 = 45

Therefore, on average, we would expect around 45 instances of rolling a one when using this biased dice over 150 rolls.

It's important to note that the actual number of ones obtained may vary due to the inherent randomness of dice rolls. However, if a biased dice has a 0.3 chance of getting a 1, when rolled 150 times, you would expect to get approximately 45 ones.

To find the simplified expression and the value of 6 raised to a power, follow the steps given below:

Step 1: Simplify the expression Firstly, the simplified expression is obtained by using the rule of exponents, which states that if a number raised to a power is multiplied by the same number raised to another power, then the resulting power is the sum of the two powers.

6 raised to the power of 2 is 6 × 6 = 36.6 raised to the power of 3 is 6 × 6 × 6 = 216.6 raised to the power of 4 is 6 × 6 × 6 × 6 = 1296.6 raised to the power of 5 is 6 × 6 × 6 × 6 × 6 = 7776.

Step 2: Find the value of the expression

From these results, it can be seen that when 6 is raised to an even power, the resulting number is even, and when 6 is raised to an odd power, the resulting number is odd. This is because 6 is an even number.

In general, if a number is even, then the result obtained when it is raised to an even power is even, and the result obtained when it is raised to an odd power is odd.

If a number is odd, then the result obtained when it is raised to any power is odd. 6 raised to the power of 8 can be written as 6 raised to the power of 4 raised to the power of 2, as shown below 6 raised to the power of 8 = (6 raised to the power of 4) raised to the power of 2= 1296 raised to the power of 2= 1,675,616

Answer:

To find the monthly payment for a 3-year auto loan at 4% annual interest compounding monthly, we can use the formula for **monthly payment for a loan**:

```

M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1]

```

where:

- M is the monthly payment

- P is the principal or amount borrowed

- i is the monthly interest rate

- n is the number of months

In this case, the principal or amount borrowed is $18,000 and the down payment is $2,000. Therefore, the principal amount that needs to be financed is $16,000.

The monthly interest rate can be calculated by dividing the annual interest rate by 12. In this case, the annual interest rate is 4%, so the monthly interest rate is 4% / 12 = 0.00333333.

The number of months can be calculated by multiplying the number of years by 12. In this case, the number of months is 3 years x 12 months/year = 36 months.

Now we can substitute these values into the formula:

```

M = $16,000 [ 0.00333333(1 + 0.00333333)^36 ] / [ (1 + 0.00333333)^36 – 1]

Answer: (1,-2)

Step-by-step explanation:

To check which of the given ordered pairs satisfy the given system of nonlinear inequalities, we will substitute the values of x and y from each ordered pair and then check if the inequalities hold true or not. Let's check one by one.

For the ordered pair (1,-2):

7 - 2(x-1)² ≤ 25 - y

7 - 2(1-1)² ≤ 25 - (-2)

7 ≤ 25 + 2

7 ≤ 27 (This is true)

2 ≤ -y

2 ≤ -(-2)

2 ≤ 2 (This is true)

Therefore, (1,-2) satisfies the given system of nonlinear inequalities.

For the ordered pair (1,-3):

7 - 2(x-1)² ≤ 25 - y

7 - 2(1-1)² ≤ 25 - (-3)

7 ≤ 28 (This is true)

2 ≤ -y

2 ≤ -(-3)

2 ≤ 3 (This is true)

Therefore, (1,-3) does not satisfy the given system of nonlinear inequalities.

For the ordered pair (1,0):

7 - 2(x-1)² ≤ 25 - y

7 - 2(1-1)² ≤ 25 - (0)

7 ≤ 25 (This is true)

2 ≤ -y

2 ≤ -(0)

2 ≤ 0 (This is not true)

Therefore, (1,0) does not satisfy the given system of nonlinear inequalities.

For the ordered pair (0,0):

We do not have the value of x for this ordered pair, so we cannot check whether it satisfies the given system of nonlinear inequalities.

Hence, the ordered pair that satisfies the given system of nonlinear inequalities is (1,-2).
