If (x-2) is a factor of [tex]f(x) = x^3 + x^2 - 16x + k.[/tex] then f(x) is divisible by (x-2) when k = 20.

If (x-2) is a factor of [tex]f(x) = x^3 + x^2 - 16x + k,[/tex] then it means that when we divide f(x) by (x-2), the remainder is zero.

To verify this, we can perform the division using polynomial long division or synthetic division.

Using synthetic division, the divisor (x-2) corresponds to the root 2:

2 | 1 1 -16 k

  2    6    -20+k

For the remainder to be zero, the last term in the synthetic division must be zero: -20 + k = 0.

Solving this equation, we find:

k = 20

Therefore, if (x-2) is a factor of [tex]f(x) = x^3 + x^2 - 16x + k,[/tex] then f(x) is divisible by (x-2) when k = 20.

In summary, if (x-2) is a factor of[tex]f(x) = x^3 + x^2 - 16x + k,[/tex]  then f(x) is divisible by (x-2) when k = 20.

The next term of the sequence is predicted to be 155.

To construct a difference table, we find the differences between consecutive terms in the sequence. Let's begin:

Sequence: 6, 2, 5, 24, 68, 146, ...

First differences:

2 - 6 = -4

5 - 2 = 3

24 - 5 = 19

68 - 24 = 44

146 - 68 = 78

...

Second differences:

3 - (-4) = 7

19 - 3 = 16

44 - 19 = 25

78 - 44 = 34

...

Third differences:

16 - 7 = 9

25 - 16 = 9

34 - 25 = 9

...

Since the third differences are constant and equal to 9, we can conclude that the given sequence is a polynomial sequence of degree 3.

Now, to predict the next term of the sequence, we need to continue the difference pattern until we reach a constant difference.

Fourth differences:

9 - 9 = 0

Fifth differences:

0

Since the fifth differences are zero, we can deduce that the polynomial sequence has a degree of 3.

Now, to predict the next term, we start with the last term of the given sequence (146) and add the final difference we obtained (9).

146 + 9 = 155

Therefore, the next term of the sequence is predicted to be 155.

To determine the best course grade your friend can earn, we need to calculate the weighted average of the scores obtained so far and the score on the final exam.

Given that the final exam counts for 15% of the course grade, we can calculate the weighted average using the formula:

Weighted average = (Weighted score on assessments) + (Weighted score on the final exam)

The weighted score on assessments is equal to (100% - 15%) = 85%, as it constitutes 85% of the course grade. We can calculate the weighted average as follows:

Weighted average = (0.85 * 84%) + (0.15 * Final exam score)

To find the best course grade your friend can earn, we need to maximize the final exam score. Since the maximum grade is 100%, the best course grade your friend can earn is when the final exam score is 100%. Substituting this value into the equation:

Weighted average = (0.85 * 84%) + (0.15 * 100%)

               = 0.714 + 0.15

               = 0.864

To express the result as a percentage, we multiply by 100:

Weighted average = 0.864 * 100

               = 86.4%

Therefore, the best course grade your friend can earn is 86.4%.

To determine the minimum score your friend would need on the final exam to earn a 75% for the course, we set up the following equation:

Weighted average = (0.85 * 84%) + (0.15 * Final exam score) = 75%

Simplifying the equation: (0.85 * 84%) + (0.15 * Final exam score) = 75%

0.714 + (0.15 * Final exam score) = 75%

0.15 * Final exam score = 75% - 0.714

0.15 * Final exam score = 74.286%

To find the minimum score, we divide both sides by 0.15:

Final exam score = 74.286% / 0.15

               = 495.24%

Therefore, your friend would need a minimum score of 495.24% on the final exam to earn a 75% for the course. However, it's important to note that scores are typically capped at 100%, so achieving a score above 100% may not be possible in this context.

The correct equation that could be used to determine the degree measure of one of the congruent angles is 2x + 43 = 180.

In a triangle, the sum of the interior angles is always 180 degrees.

Given that one interior angle of the triangle is 43 degrees, and the other two angles are congruent, we can represent the measure of one of the congruent angles with the variable x.

To determine the degree measure of one of the congruent angles, we can set up an equation using the fact that the sum of all three interior angles of a triangle is 180 degrees.

The equation that represents the situation is:

2x + 43 = 180

This equation accounts for the 43 degrees angle given and represents the sum of the two congruent angles (2x) plus the 43-degree angle equaling 180 degrees.

Solving this equation will allow us to find the value of x, which represents the degree measure of one of the congruent angles.

Once we find the value of x, we can substitute it back into the equation to find the actual degree measure of the congruent angle.

a) To maximize profits, 10 units should be sold in market 1 and 5 units in market 2.

b) The corresponding prices are $180 in market 1 and $160 in market 2.

c) If it becomes illegal to discriminate, the profit loss is $50.

d) The imposition of a tax of $5 per unit sold in market 1 would likely decrease the monopolist's profit and potentially lead to adjustments in prices and quantities sold in both markets.

a) To maximize profits, the monopolist should set marginal revenue equal to marginal cost in each market.

In this case, marginal revenue is equal to the derivative of the demand function with respect to quantity, and it can be calculated as MR = dP/dQ.

For market 1:

MR₁ = dP₁/dQ₁ = -2

For market 2:

MR₂ = dP₂/dQ₂ = -4

Setting MR equal to marginal cost, which is the derivative of the cost function with respect to quantity, gives:

MR₁ = -2 = dC/dQ₁ = 20

MR₂ = -4 = dC/dQ₂ = 20

Solving these equations, we find:

Q₁ = 10

Q₂ = 5

Therefore, the monopolist should sell 10 units in market 1 and 5 units in market 2 to maximize profits.

b) To determine the corresponding prices, we substitute the quantities obtained in part (a) into the demand functions:

For market 1:

P₁ = 200 - 2Q₁ = 200 - 2(10) = 180

For market 2:

P₂ = 180 - 4Q₂ = 180 - 4(5) = 160

Therefore, the corresponding prices are $180 in market 1 and $160 in market 2.

c) To calculate the profit lost if it becomes illegal to discriminate, we need to compare the profits under discrimination with the profits under non-discrimination.

Under discrimination, the monopolist charges different prices in each market, while under non-discrimination, the same price is charged in both markets.

Under discrimination:

Profit = Total revenue - Total cost

For market 1:

Total revenue₁ = P₁ [tex]\times[/tex] Q₁ = 180 [tex]\times[/tex] 10 = $1

For market 2:

Total revenue₂ = P₂ [tex]\times[/tex] Q₂ = 160 [tex]\times[/tex] 5 = $800

Total revenue = Total revenue₁ + Total revenue₂ = $1800 + $800 = $2600

Total cost = C = 20(Q₁ + Q₂) = 20(10 + 5) = $300

Profit = Total revenue - Total cost = $2600 - $300 = $2300

Under non-discrimination:

Since the same price is charged in both markets, we take the average price:

Average price = (P₁ + P₂) / 2 = (180 + 160) / 2 = $170

Total revenue = Average price [tex]\times[/tex] (Q₁ + Q₂) = $170 [tex]\times[/tex] (10 + 5) = $2550

Total cost remains the same at $300.

Profit = Total revenue - Total cost = $2550 - $300 = $2250

Therefore, the profit lost if discrimination becomes illegal is $2300 - $2250 = $50.

d) The imposition of a tax of $5 per unit sold in market 1 would increase the cost per unit for the monopolist.

This would affect the profit-maximizing quantity in market 1 and potentially lead to a change in prices.

The monopolist would compare the new marginal cost, which includes the tax, with the marginal revenue to determine the new profit-maximizing quantities and prices.

The tax would likely reduce the monopolist's profits and could potentially result in adjustments in production and pricing strategies.

The equation to calculate the yearly interest earned on your investment of $750 at a 16% interest rate is: Interest = $750 * 0.16.

To write the equation for calculating the yearly interest earned on an investment, we can use the formula:

Interest = Principal * Rate

Where:

- Principal is the initial investment amount.

- Rate is the interest rate expressed as a decimal.

In this case, you invested $750, and the annual interest rate is 16%. To use the decimal form of the interest rate, we divide it by 100:

Rate = 16% = 16/100 = 0.16

Substituting the values into the equation:

Interest = $750 * 0.16

To calculate the interest, we multiply the principal by the interest rate:

Interest = $750 * 0.16 = $120

Therefore, the equation to calculate the yearly interest earned on your investment of $750 at a 16% interest rate is:

Interest = $750 * 0.16

Now, let's complete a table to show the growth of your investment over multiple years. We'll assume the interest is compounded annually.

Year | Initial Investment | Interest Earned | Total Value

---------------------------------------------------------

 1        $750                 $120              $870

 2        $870                 $139.20          $1009.20

 3        $1009.20            $161.47          $1170.67

 4        $1170.67            $187.31          $1357.98

 5        $1357.98            $217.28          $1575.26

In each year, we calculate the interest earned by multiplying the initial investment by the interest rate (16% or 0.16). The total value is obtained by adding the initial investment and the interest earned. This process is repeated for each subsequent year.

The table shows the growth of your investment over five years, demonstrating how the interest compounds and increases the total value each year.

Given statement solution is :- Interpreting the steady matrix:

The value 0.6 in the top left cell represents the proportion of customers who turn in tickets this week and will turn in tickets again next week.

The value 0.3 in the top right cell represents the proportion of customers who turn in tickets this week but will not turn in tickets next week.

The steady matrix provides a snapshot of the probabilities of transitioning between the two states (turning in tickets or not turning in tickets) in the long run, assuming these probabilities remain constant over time.

To analyze the steady matrix for this situation, let's consider the two groups of customers: those who turn in tickets and those who do not turn in tickets.

Let's denote the proportion of customers who turn in tickets as X and the proportion of customers who do not turn in tickets as Y.

According to the given information:

40% of the customers who turn in tickets do not turn in tickets the following week. This means that 60% of the customers who turn in tickets will turn in tickets again the following week.

30% of the customers who do not turn in tickets will turn in tickets the following week. This means that 70% of the customers who do not turn in tickets will continue not turning in tickets the following week.

Based on these percentages, we can construct the steady matrix:

Next week 0.6 0.3

This week 0.4 0.7

Interpreting the steady matrix:

The value 0.6 in the top left cell represents the proportion of customers who turn in tickets this week and will turn in tickets again next week.

The value 0.3 in the top right cell represents the proportion of customers who turn in tickets this week but will not turn in tickets next week.

The value 0.4 in the bottom left cell represents the proportion of customers who do not turn in tickets this week but will turn in tickets next week.

The value 0.7 in the bottom right cell represents the proportion of customers who do not turn in tickets this week and will continue not turning in tickets next week.

These values describe the transition probabilities between the two customer groups. For example, if there are 100 customers in total, 60 of them will turn in tickets next week, and 40 of them will not. Similarly, 30 customers who turn in tickets this week will not do so next week, while 70 customers who do not turn in tickets this week will continue to not turn them in next week.

The price for which 12.3% of milk vendors exceeded is approximately $3.32 (rounded to the nearest cent).

To find the price for which 12.3% of milk vendors exceeded, we need to find the corresponding z-score and then use it to determine the price using the standard normal distribution table.

First, we calculate the z-score using the formula:

z = (x - μ) / σ

where x is the price, μ is the mean, and σ is the standard deviation.

In this case, the mean μ is $3.20 and the standard deviation σ is $0.10. We want to find the price x for which 12.3% of vendors exceeded, so we need to find the z-score corresponding to the cumulative probability of 1 - 12.3% = 87.7%.

Using a standard normal distribution table or calculator, we find that the z-score corresponding to 87.7% is approximately 1.17.

Now, we can rearrange the formula to solve for x:

x = μ + z [tex]\times[/tex] σ

x = $3.20 + 1.17 [tex]\times[/tex] $0.10

x ≈ $3.20 + $0.117

Answer:

x = 65.26 degrees or x = 245.26 degrees.

Step-by-step explanation:

To solve the equation 4tan(x)-7=0 for 0<=x<360, we can first isolate the tangent term by adding 7 to both sides:

4tan(x) = 7

Then, we can divide both sides by 4 to get:

tan(x) = 7/4

Now, we need to find the values of x that satisfy this equation. We can use the inverse tangent function (also known as arctan or tan^-1) to do this. Taking the inverse tangent of both sides, we get:

x = tan^-1(7/4)

Using a calculator or a table of trigonometric values, we can find the value of arctan(7/4) to be approximately 65.26 degrees (remember to use the appropriate units, either degrees or radians).

However, we need to be careful here, because the tangent function has a period of 180 degrees (or pi radians), which means that it repeats every 180 degrees. Therefore, there are actually two solutions to this equation in the given domain of 0<=x<360: one in the first quadrant (0 to 90 degrees) and one in the third quadrant (180 to 270 degrees).

To find the solution in the first quadrant, we can simply use the value we just calculated:

x = 65.26 degrees (rounded to two decimal places)

To find the solution in the third quadrant, we can add 180 degrees to the first quadrant solution:

x = 65.26 + 180 = 245.26 degrees (rounded to two decimal places)

So the solutions to the equation 4tan(x)-7=0 for 0<=x<360 are:

x = 65.26 degrees or x = 245.26 degrees.

The area of the region bounded by the graphs y = x² and y = x + 6 over the domain of [-3, 4] is 41.33 square units.

To plot the graphs of f(x) = x² and g(x) = x + 6 on the same axis, we can create a coordinate system with x-values ranging from -3 to 4.

We can start by evaluating the y-values for each function within this domain.

For f(x) = x²:

When x = -3, y = (-3)² = 9

When x = -2, y = (-2)² = 4

When x = -1, y = (-1)² = 1

When x = 0, y = (0)² = 0

When x = 1, y = (1)² = 1

When x = 2, y = (2)² = 4

When x = 3, y = (3)² = 9

When x = 4, y = (4)² = 16

For g(x) = x + 6:

When x = -3, y = -3 + 6 = 3

When x = -2, y = -2 + 6 = 4

When x = -1, y = -1 + 6 = 5

When x = 0, y = 0 + 6 = 6

When x = 1, y = 1 + 6 = 7

When x = 2, y = 2 + 6 = 8

When x = 3, y = 3 + 6 = 9

When x = 4, y = 4 + 6 = 10

Plotting these points on a graph, Graph is given at the bottom.

b) Shaded and display the region bounded by the graphs f(x) and domain of [-3, 4]:

To shade and display the region bounded by the graphs f(x) = x² and the domain of [-3, 4], we need to shade the area between the two curves over this domain.

The shaded region represents the area enclosed by the two curves.

c) Evaluate the area from x = -2 to x = 3:

To find the area of the region bounded by the graphs, we need to determine the points of intersection between the two curves. By setting the two equations equal to each other, we can solve for x:

x² = x + 6

Rearranging the equation, we get:

x² - x - 6 = 0

Factoring the quadratic equation, we have:

(x - 3)(x + 2) = 0

This gives us two solutions: x = 3 and x = -2. These are the x-coordinates of the points of intersection.

By evaluating the definite integral of the difference between the two curves over the interval [-2, 3], we can find the area of the region bounded by the graphs.
Using the integral notation, we have: ∫[from -2 to 3] (x + 6 - x²) dx

Integrating each term separately, we have:

∫(x dx) = (1/2)x² + C1

∫(6 dx) = 6x + C2

∫(x² dx) = (1/3)x³ + C3

To find the definite integral over the interval [-2, 3], we evaluate each integral at the upper and lower limits and subtract:

∫[from -2 to 3] (x + 6 - x²) dx = [(1/2)(3)² + C1 + 6(3) + C2 + (1/3)(3)² + C3] - [(1/2)(-2)² + C1 + 6(-2) + C2 + (1/3)(-2)² + C3]

Simplifying, we have:

= [(1/2)(9) + C1 + 18 + C2 + (1/3)(27) + C3] - [(1/2)(4) + C1 - 12 + C2 + (1/3)(-8) + C3]

= [4.5 + C1 + 18 + C2 + 9 + C3] - [2 + C1 - 12 + C2 - 8/3 + C3]

= (4.5 + 18 + 9) - (2 - 12 - 8/3)

= 31.5 + 2/3

≈ 41.33 square units

Therefore, the area of the region bounded by the graphs y = x² and y = x + 6 over the interval [-2, 3] is approximately 41.33 square units.

The value of x is approximately 8.4.To find the value of x, we can use the fact that CD is parallel to BE to establish a relationship between the corresponding sides of the two triangles formed.

Based on the given information, we have:

DC = 4x - 11

BE = 6

AD = 15

ED = 4

Using the corresponding sides in the triangles, we can set up a proportion:

AD/ED = CD/BE

Substituting the known values:

15/4 = (4x - 11)/6

Now we can cross-multiply to solve for x:

6 * 15 = 4 * (4x - 11)

90 = 16x - 44

Adding 44 to both sides:

134 = 16x

Dividing both sides by 16:

x = 8.375

Rounded to the nearest tenth, x ≈ 8.4.

The x-coordinate of point C is -70.

To find the y-intercept and equation of the line passing through points A(14, -1) and B(2, 1), we can use the slope-intercept form of a linear equation, which is y = mx + b, where m represents the slope and b represents the y-intercept.

First, let's find the slope (m) using the formula:

m = (y₂ - y₁) / (x₂ - x₁)

m = (1 - (-1)) / (2 - 14) = 2 / (-12) = -1/6

Next, we can substitute the coordinates of point A and the slope into the slope-intercept form:

-1 = (-1/6)(14) + b

Solving for b:

-1 = -7/3 + b

b = -1 + 7/3

b = -3/3 + 7/3

b = 4/3

Therefore, the equation of the line passing through points A and B is:

y = (-1/6)x + 4/3

Now, let's find the x-coordinate of point C when its y-coordinate is 13.

We can substitute the y-coordinate into the equation and solve for x:

13 = (-1/6)x + 4/3

Multiplying the equation by 6 to eliminate the fraction:

78 = -x + 8

Subtracting 8 from both sides:

70 = -x

Dividing by -1:

x = -70.

Step-by-step explanation:

The tugboat is approximately 588.235 feet away from the top of the lighthouse.

To find the distance between the tugboat and the top of the lighthouse, we can use trigonometry and the concept of tangent.

Let's denote the distance between the tugboat and the top of the lighthouse as x.

We know that the angle of elevation is 12° and the height of the lighthouse is 125 feet.

In a right triangle, the tangent of an angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.

In this case, the tangent of the angle of elevation is equal to the height of the lighthouse divided by the distance between the tugboat and the lighthouse:

tan(12°) = 125 / x

To find x, we need to isolate it on one side of the equation.

We can do this by taking the inverse tangent (arctan) of both sides:

x = 125 / tan(12°)

Using a calculator, we can calculate the value of the tangent of 12°:

tan(12°) ≈ 0.212556

Now, we can substitute this value into the equation to find x:

x = 125 / 0.212556 ≈ 588.235

The trend appears to be linear. Assuming the trend continues, the number of unemployed will first reach 43 in the year 2022.

To determine whether the trend appears linear, we can plot the data points on a graph and check for a consistent pattern. Let's create a scatter plot with the years on the x-axis and the number of unemployed on the y-axis.

Year     |  Number Unemployed

1990     |  750

1992     |  670

1994     |  650

1996     |  605

1998     |  550

2000     |  510

2002     |  460

2004     |  420

2006     |  380

2008     |  320

When we plot these points, we can see that there is a consistent downward trend in the number of unemployed over the years.

Next, we can try to fit a line to the data points to see if it follows a linear pattern. Using a linear regression model or by visual inspection, we can determine that the data points approximately follow a straight line.

Assuming this linear trend continues, we can extrapolate to find the year when the number of unemployed first reaches 43. By extending the line beyond the given data points, we can estimate that it will intersect the y-axis (number of unemployed) at approximately 43.

Therefore, the year when the number of unemployed first reaches 43 would be around 2022.

The probability that a random point on AK will be on DF is 0.4 or 40%.

The given line segments have coordinates on a coordinate plane. To find the probability that a random point on AK will be on DF, we have to determine the length of AK and DF.

Firstly, we need to find the coordinates of D and F, which can be determined from the given coordinates. The coordinates of D are (-4, 8) and the coordinates of F are (4, 8).

Therefore, the length of DF can be found by applying the distance formula as shown below: DF = √((4-(-4))² + (8-8)²)DF = √(8² + 0²)DF = √64DF = 8  Similarly, we can find the coordinates of A and K as well.

The coordinates of A are (-10, 6) and the coordinates of K are (10, 6).Therefore, the length of AK can be found by applying the distance formula as shown below: AK = √((10-(-10))² + (6-6)²)AK = √(20² + 0²)AK = √400AK = 20.

Therefore, we can find the probability that a random point on AK will be on DF by using the formula: P = Length of DF / Length of AKSubstituting the values, we get P = 8/20P = 0.4 or 40%

Answer:

To solve the given simultaneous equations: 2x + y = 5 ------------(1) 2x^2 + y^2 = 11 ------------(2)

We can use the method of substitution to solve the equations.

Substituting y = 5 - 2x from equation (1) into equation (2), we get: 2x^2 + (5 - 2x)^2 = 112x^2 + 25 - 20x + 4x^2 = 112x^2 + 4x^2 - 20x + 25 - 11 =

simplifying, we get: 6x^2 - 20x + 14 = 0

Dividing by 2, we get: 3x^2 - 10x + 7 = 0

Factorizing, we get: (3x - 7)(x - 1) = 0

Solving for x, we get: x = 1 or x = 7/3

Now substituting x = 1 in equation (1), we get:2(1) + y = 5y = 5 - 2y = 3 Therefore, one solution is x = 1 and y = 3

Substituting x = 7/3 in equation (1), we get: 2(7/3) + y = 5y = 5 - 14/3y = 1/3

Therefore, the other solution is x = 7/3 and y = 1/3

Hence, the solutions of the given simultaneous equations are x = 1 and y = 3 or x = 7/3 and y = 1/3.
