Jill's annual earnings can be calculated by multiplying her weekly pay by the number of weeks in a year: $298/week x 52 weeks/year = $15,496/year. Her earnings to date are $14,900, so she has earned an additional $596 in the current week.

Social Security is taxed at 6.2%, so the amount deducted from her pay each week is 6.2% of her gross weekly pay. That's 0.062 x $298 = $18.48.

The characteristics that tell you that the graph shows a proportional relationship are: A straight line can be drawn through the points and The line connecting the points passes through the origin. Option B and D are the correct answer.

A proportional relationship is a relationship between two variables where the ratio of their values is constant. This means that if we multiply one of the values by a constant, the other value also gets multiplied by the same constant.

The graph of a proportional relationship is a straight line that passes through the origin. This is because the ratio of the x- and y-values is constant, so the points can be plotted as a straight line.

The ordered pairs all have the same x- and y-values means that the two variables are perfectly correlated. This is not necessary for a proportional relationship, but it is a common characteristic.

The line connecting the points does not need to pass through the origin for the relationship to be proportional. However, if the line does pass through the origin, then the two variables are directly proportional. Option B and D are the correct answer.

In 2006, the population will reach 109 million.

The correct answer is an option (d)

Here function [tex]f(x)=100(1.0153)^x[/tex] represents the population (in millions) x years after 2000

We need to find the year x when the population will reach 109 million.

i.e., for f(x) = 109, we need to find the value of x.

Consider function f(x),

[tex]f(x)=100(1.0153)^x[/tex]

Substitute f(x) = 109

⇒ [tex]109=100(1.0153)^x[/tex]

⇒ [tex](1.0153)^x=1.09[/tex]

Taking logarithm on both the sides.

⇒ x ln(1.0153) = ln(1.09)

⇒ x = ln(1.09) / ln(1.0153)

⇒ x = 5.675

⇒ x ≈ 6

So, the required year would be,

If Point A is located at (1, 2) and Point B is located at (4, 6), the length of the line between points A and B is 5 units.

To determine the length of the line between points A and B, we can use the distance formula, which is a formula used to calculate the distance between two points in a coordinate plane. The distance formula is:

d = √((x₂ - x₁)² + (y₂ - y₁)²)

where (x₁, y₁) and (x₂, y₂) are the coordinates of the two points and d is the distance between them.

Using the coordinates of points A and B, we can substitute their values into the distance formula to find the length of the line between them:

d = √((4 - 1)² + (6 - 2)²)

d = √(3² + 4²)

d = √(9 + 16)

d = √25

d = 5

Rounded to the nearest whole number, the length of the line is also 5 units.

In conclusion, we can use the distance formula to find the length of the line between two points in a coordinate plane. The distance formula uses the coordinates of the two points to calculate the distance between them. The resulting distance can be rounded to the nearest whole number, if needed.

The area of this​ trapezoid is 14.42 square yards.

To compose the trapezoid into a parallelogram, we need to add a triangle to the top of the trapezoid, so that the top and bottom sides are parallel. The area of the triangle is equal to half the product of the base and height.

First, we need to convert the mixed numbers to improper fractions:

Base 1: 6 1/3 yd = 19/3 yd

Base 2: 8 1/5 yd = 41/5 yd

Height: 3 3/4 yd = 15/4 yd

The length of the top side of the triangle is equal to the difference between the two bases:

Top side = 41/5 - 19/3 = (123 - 95)/15 = 28/15

Now we can calculate the area of the triangle:

Triangle area = (1/2) x (28/15) x (15/4) = 7/4

The trapezoid can now be composed into a parallelogram, with base 1 as one side and base 2 as the other side. The height of the parallelogram is the same as the height of the trapezoid, which is 15/4 yd.

The area of a parallelogram is equal to the product of its base and height, so the area of the trapezoid is:

Parallelogram area = (19/3 + 41/5) x (15/4) = 865/60 = 14.42

Therefore, the area of the trapezoid is 14.42 square yards.

Carleigh, Inc. should separate the organ meats from the residual and sell them abroad, as it would increase their total revenue by $17,150 per week.

To determine whether Carleigh, Inc. should separate the organ meats and sell them abroad, we need to calculate the incremental revenue and incremental costs associated with this decision.

The incremental revenue would be the revenue generated from selling the organ meats abroad, which is $52,000 per week. The incremental cost would include the cost of further processing ($27,500 per week), transportation cost ($12,100 per week), and the increase in resource spending for other activities ($3,120 per week).

Therefore, the incremental cost would be $42,720 per week. Subtracting this from the incremental revenue of $52,000, we get an incremental profit of $9,280 per week.

However, this decision would also decrease the value of the residual from $9,800 to $2,650 per week. Therefore, we need to subtract this decrease in value from the incremental profit. This gives us a net increase in profit of $17,150 per week ($9,280 - $7,130).

If new equation of this line be after it is rotated 90° counterclockwise around the origin, the equation of the new line after rotation is y = (-5/6)x

To find the new equation of a line after it is rotated 90° counterclockwise around the origin, we need to use the following formula:

(x', y') = (-y, x)

where (x, y) are the coordinates of a point on the original line, and (x', y') are the coordinates of the corresponding point on the new line after rotation.

We can start by finding the slope of the original line, which is given by:

y = (6x/5)

Rearranging this equation, we get:

x = (5/6)y

This tells us that the slope of the original line is 5/6.

To find the equation of the new line after rotation, we need to apply the formula above to two points on the original line. Let's choose two easy points to work with, such as (0,0) and (5,6).

Using the formula, we can find the new coordinates of these points after rotation:

(0', 0') = (-0, 0) = (0,0)

(5', 6') = (-6, 5)

Now we can find the slope of the new line using these two points:

slope = (6' - 0') / (5' - 0') = 5/-6 = -5/6

In summary, to find the new equation of a line after rotating 90° counterclockwise around the origin, we can use the formula (x', y') = (-y, x) to find the new coordinates of two points on the original line, and then use these points to find the slope of the new line. In this case, the new equation of the line is y = (-5/6)x.

To demonstrate our point, mathematical induction can be employed.

We want to prove that the given formula holds for all natural numbers n:

S(n) = 36 + 324 + 900 + ... + (12n - 6)² = 12n(4n² - 1)

Using mathematical induction:

Step 1: Base case (n=1)

S(1) = 6² = 36

12 * 1 * (4 * 1² - 1) = 36

Since S(1) holds true, the base case is proven.

Step 2: Inductive step (Assume it's true for n=k, and show it's true for n=k+1)

Assumption: S(k) = 36 + 324 + 900 + ... + (12k - 6)² = 12k(4k² - 1)

We follow the exhaustive process to prove:

Since both expressions for S(k+1) are equal, the inductive step is proven.

USD 438

Step-by-step explanation:If we add 20% to the gross amount of USD 365, the total amount would be:USD 365 + 20% of USD 365 = USD 365 + (0.20 * USD 365) = USD 365 + USD 73 = USD 438

If the gross amount is USD 365, then the net amount after adding 20 percent is USD 438.

Net amount refers to the final total after deductions or additions have been made whereas gross amount refers to the total amount before any deductions or additions have been made.

Us the formula:

Net Amount = Gross Amount + (Gross Amount x Percentage)

Given that,

Gross amount = $365

The given percentage = 20%

We can write 20% = 20/100

So, 20% = 0.2

Now put the values into the formula

Net amount  = 365 + (365 x 0.2)

Answer:

The expected value in this situation can be calculated as follows:

E(X) = P(X) * V(X), where X is the random variable representing the profit of the construction company, P(X) is the probability of X, and V(X) is the value of X.

In this case, the profit of the construction company if the bid is accepted is $96,000 - $1,100 = $94,900, and the probability of the bid being accepted is 1/10. Therefore, we have:

E(X) = (1/10) * $94,900 = $9,490

The expected value of $9,490 means that in the long run, the construction company would expect to earn this amount on average per bid. Therefore, the correct answer is option A: "In the long run, the construction company would expect to earn this amount on average per bid."
