Answer:

86.6%

Step-by-step explanation:

new mark = (previous mark x weight of previous work) + (new mark x weight of new work)

In this case, your previous mark is 83%, and it is weighted at 70% (100% - 30%). Your new mark is 95%, and it is weighted at 30%. Substituting these values into the formula, we get:

new mark = (83% x 0.7) + (95% x 0.3)

new mark = 58.1% + 28.5%

new mark = 86.6%

So, your mark now is 86.6%

Answer:

86.6%

Step-by-step explanation:

Since the summative is worth 30% of the grade, then the average of 83% is worth 70% of the grade.

70% of 83% + 30% of 90% = 0.7 × 83% + 0.3 × 95% = 58.1% + 28.5% = 86.6%

Answer: 86.6%

To find the area of material needed to make each cone-shaped hat, we need to calculate the lateral surface area of the cone. The lateral surface area represents the curved surface area of the cone, excluding the base.

The formula for the lateral surface area of a cone is given by:

Lateral Surface Area = π * r * slant height

Where π is approximately 3.14159, r is the radius of the base, and the slant height is the distance from the tip of the cone to any point on the circumference of the base.

In this case, the diameter of the cone-shaped hat is 4 inches, which means the radius (r) is half of that, so r = 4 / 2 = 2 inches. The slant height is given as 6.8 inches.

Substituting these values into the formula, we have:

Lateral Surface Area = 3.14159 * 2 * 6.8

= 42.7196 square inches

Rounded to the nearest tenth, the area of material needed to make each cone-shaped hat, assuming there is no overlap of material, is approximately 42.7 square inches.

The polynomial function with rational coefficients that has the roots -4 and 2i is P(x) = x^3 + 4x^2 + 4x + 16.

To find a polynomial function with rational coefficients that has the roots -4 and 2i, we need to consider the fact that complex roots always come in conjugate pairs. This means that if 2i is a root, then its conjugate -2i must also be a root of the polynomial.

Now, let's construct the polynomial function step by step:

Start with the linear factors for each root:

(x - (-4)) = (x + 4)  // for the root -4

(x - (2i)) = (x - 2i) // for the root 2i

Since complex roots come in conjugate pairs, we include the conjugate of (x - 2i), which is (x + 2i):

(x + 2i) // for the conjugate root -2i

Combine all the linear factors together:

(x + 4)(x - 2i)(x + 2i)

Simplify the expression using the difference of squares formula: (a^2 - b^2) = (a + b)(a - b):

(x + 4)((x)^2 - (2i)^2)

Expand and simplify further:

(x + 4)(x^2 + 4)

= x(x^2 + 4) + 4(x^2 + 4)

= x^3 + 4x + 4x^2 + 16

= x^3 + 4x^2 + 4x + 16

Therefore, the polynomial function with rational coefficients that has the roots -4 and 2i is P(x) = x^3 + 4x^2 + 4x + 16.

To cover a 100 ft * 82 ft ceiling with gold leaf that is five-millionths of an inch thick, the amount of gold need is approximately 60.135 troy ounces, costing approximately $99,481.59.

To find the amount of gold needed, we can start by calculating the area of the ceiling. The area of a rectangle is found by multiplying its length by its width. In this case, the length is 100 ft and the width is 82 ft, so the area of the ceiling is 100 ft * 82 ft = 8,200 sq ft.

Next, we need to convert the area from square feet to square inches because the thickness of the gold leaf is given in inches. Since there are 12 inches in a foot, we can multiply the area by 12 * 12 = 144 to get the area in square inches. Therefore, the area of the ceiling in square inches is 8,200 sq ft * 144 = 1,180,800 sq in.

To find the volume of gold leaf needed, we multiply the area by the thickness of the gold leaf. The thickness is given as five-millionths of an inch, which can be written as 5/1,000,000 inches. So, the volume of gold leaf needed is 1,180,800 sq in * 5/1,000,000 in = 5.904 cu in.

Since the density of gold is 19.32 g/cm^3, we can convert the volume from cubic inches to cubic centimeters by multiplying by the conversion factor 16.39 (1 cu in = 16.39 cu cm). Therefore, the volume of gold leaf needed is 5.904 cu in * 16.39 cu cm/cu in = 96.7 cu cm.

To find the mass of gold needed, we multiply the volume by the density. So, the mass of gold needed is 96.7 cu cm * 19.32 g/cu cm = 1,870.724 g.

Since gold is usually measured in troy ounces, we need to convert the mass from grams to troy ounces. There are 31.1035 grams in 1 troy ounce. Therefore, the mass of gold needed is 1,870.724 g / 31.1035 g/troy oz = 60.135 troy oz.

Lastly, to find the cost of the gold, we multiply the mass by the cost per troy ounce. The cost per troy ounce is $1654. Therefore, the cost of the gold needed is 60.135 troy oz * $1654/troy oz = $99,481.59.

In conclusion, to cover a 100 ft * 82 ft ceiling with gold leaf that is five-millionths of an inch thick, approximately 60.135 troy ounces of gold will be needed, costing approximately $99,481.59.

In a rhombus, opposite angles are congruent. Therefore, ∠BCD and ∠BAC are opposite angles in the rhombus ABCD. Since we are given that m∠BCD = 64 degrees, we can conclude that m∠BAC must also be 64 degrees.

This is because in a rhombus, the opposite angles are equal, meaning they have the same measure. Therefore, if one of the opposite angles measures 64 degrees, the other opposite angle must also measure 64 degrees. Thus, m∠BAC = 64 degrees.

The solution to the equation is x = 4/3.

We have,

Step 1: Simplify the equation.

To simplify, we can start by cross-multiplying the equation:

3 * (x² - 1) = 1 * (x + 1)

Expanding the multiplication:

3x² - 3 = x + 1

Step 2: Rearrange the equation.

Move all terms to one side to form a quadratic equation:

3x² - x - 4 = 0

Step 3: Solve the quadratic equation.

x = (-b ± √(b² - 4ac)) / (2a)

Applying the values a = 3, b = -1, and c = -4:

x = (-(-1) ± √((-1)² - 4 * 3 * -4)) / (2 * 3)

x = (1 ± √(1 + 48)) / 6

x = (1 ± √49) / 6

x = (1 ± 7) / 6

This yields two possible solutions:

x₁ = (1 + 7) / 6 = 8 / 6 = 4/3

x₂ = (1 - 7) / 6 = -6 / 6 = -1

Step 4: Check the solutions.

Let's substitute the values of x back into the original equation and verify if they hold true:

For x = 4/3:

Left-hand side: 3 / (4/3 + 1) = 3 / (7/3) = 9/7

Right-hand side: 1 / ((4/3)² - 1) = 1 / (16/9 - 1) = 1 / (16/9 - 9/9) = 1 / (7/9) = 9/7

The left-hand side and right-hand side are equal, so x = 4/3 is a valid solution.

For x = -1:

Left-hand side: 3 / (-1 + 1) = 3 / 0 (undefined)

Right-hand side: 1 / ((-1)² - 1) = 1 / (1 - 1) = 1 / 0 (undefined)

In this case, the equation is undefined for x = -1.

If we know that hanj is a decreasing sequence and all its terms lie between the numbers 5 and 8, it can be explained as follows:

Decreasing Sequence: The term "decreasing sequence" means that each subsequent term in the sequence is smaller than its preceding term. In the case of hanj, this implies that each hanj term is smaller than the one that comes before it. This information establishes the order and pattern of the sequence.

Upper Bound: The fact that all the terms of hanj lie between the numbers 5 and 8 indicates that no term in the sequence exceeds the value of 8. This upper bound of 8 sets a limit on the magnitude of the hanj terms, ensuring they do not exceed this value.

Lower Bound: Similarly, the statement suggests that none of the hanj terms is less than the number 5. This establishes a lower bound for the sequence, indicating that the terms are not smaller than 5.

Combining these two bounds (5 and 8) along with the decreasing nature of the sequence, we can conclude that the hanj sequence is a monotonically decreasing sequence with terms ranging from 5 to 8, inclusive.

The pirate game involves proposing coin divisions, voting on proposals, and executing unsuccessful proposers. Tie votes give the strongest pirate an extra vote.

Pirate A proposes a division of coins, and all pirates vote on whether to accept it. If the proposal gets a majority vote, it is accepted and the game ends. If the proposal fails to get a majority vote, Pirate A is executed, and Pirate B gets a turn to propose a division.

The same rules apply, except that if there is a tie vote, the strongest remaining pirate gets an additional vote to break the tie.

The game involves a strategic decision-making process among the pirates, as each pirate wants to maximize their share of the coins while avoiding being executed. Pirate A must carefully consider their proposal to gain majority support. If they fail to do so, Pirate B has an opportunity to propose a more favorable division.

The presence of a tie-breaker vote for the strongest pirate adds an extra layer of complexity, as it can influence the outcome and potentially affect the division of coins.

Guilder has 9.6 million workers, each capable of producing 1 block of X or 4 wagonloads of Y per year. By analyzing their production possibilities frontiers (PPFs) and comparing their labor productivity, we can determine their absolute and comparative advantages, and predict the outcome of free trade.

a) The PPFs for Florin and Guilder can be plotted with X on the horizontal axis and Y on the vertical axis. Given that each country allocates one-third of its labor force to dairy production and two-thirds to wheat farming, we can identify the consumption points (A and A*) where the indifference curves representing their preferences intersect with their PPFs.

b) The PPF equation for Florin can be written as X = 2L/3 and Y = 6L/3, where L represents the labor force. For Guilder, the PPF equation is X = L/9.6 and Y = 4L/9.6.

c) Guilder has the absolute advantage in producing Y as its workers are more productive in Y compared to Florin. However, Florin has the comparative advantage in producing Y because the opportunity cost of producing Y in terms of X is lower for Florin than Guilder.

d) Under free trade, Guilder would export Y and Florin would export X. This is based on the principle of comparative advantage, where each country specializes in producing the good for which it has a lower opportunity cost.

e) When both countries fully specialize and trade, there can be a higher total production of both X and Y compared to the previous consumption points (A and A*).

Control charts, such as the X-bar and R charts or the X-bar and S charts, are commonly used in SPC to monitor the mean and variability of a process.

For example, let's say a manufacturing company wants to measure the quality characteristics of its production line. The company can collect data on key quality indicators, such as product dimensions or defects, at regular intervals. Using SPC, the company can create control charts to track these measurements over time. If the data points fall within the control limits, it indicates that the process is stable and in control. However, if there are any data points outside the control limits or any patterns or trends observed, it may indicate a problem that requires investigation and corrective action.

The integral [tex]\int\limits^6_{-6} {(x + 4)\sqrt{36 - x^2}} \, dx[/tex] when evaluated is 72π

From the question, we have the following parameters that can be used in our computation:

[tex]\int\limits^6_{-6} {(x + 4)\sqrt{36 - x^2}} \, dx[/tex]

Expand

[tex]\int\limits^6_{-6} {(x + 4)\sqrt{36 - x^2}} \, dx = \int\limits^6_{-6} {[x\sqrt{36 - x^2} + 4\sqrt{36 - x^2}}] \, dx[/tex]

So, we have

[tex]\int\limits^6_{-6} {(x + 4)\sqrt{36 - x^2}} \, dx = \int\limits^6_{-6} {[x\sqrt{36 - x^2} dx+ 4\int\limits^6_{-6}\sqrt{36 - x^2}}] \, dx[/tex]

Let u = 36 - x² and du = -2x

So, we have:

[tex]\int\limits^6_{-6} {(x + 4)\sqrt{36 - x^2}} \, dx = [-\frac{(36 - x^2)^\frac 32}{3}]|\limits^6_{-6} + 4\int\limits^6_{-6}\sqrt{36 - x^2}}] \, dx[/tex]

Next, we have

x = 6sin(u), where [tex]u = \sin^{-1}(\frac x6})[/tex]

This gives

dx = 6cos(u)du

So, we have

[tex]\int\limits^6_{-6} {(x + 4)\sqrt{36 - x^2}} \, dx = [-\frac{(36 - x^2)^\frac 32}{3}]|\limits^6_{-6} + 4\int\limits^6_{-6} 6\cos(u) \sqrt{36 - 36\sin^2(u)}}] \, du[/tex]

Factor out √36

[tex]\int\limits^6_{-6} {(x + 4)\sqrt{36 - x^2}} \, dx = [-\frac{(36 - x^2)^\frac 32}{3}]|\limits^6_{-6} + 4\int\limits^6_{-6} 6\cos(u) * 6\sqrt{1 - \sin^2(u)}}] \, du[/tex]

Rewrite as

[tex]\int\limits^6_{-6} {(x + 4)\sqrt{36 - x^2}} \, dx = [-\frac{(36 - x^2)^\frac 32}{3}]|\limits^6_{-6} + 4\int\limits^6_{-6} 6\cos(u) * 6\sqrt{\cos^2(u)}}] \, du[/tex]

So, we have

[tex]\int\limits^6_{-6} {(x + 4)\sqrt{36 - x^2}} \, dx = [-\frac{(36 - x^2)^\frac 32}{3}]|\limits^6_{-6} + 4\int\limits^6_{-6} 6\cos(u) * 6\cos(u)}] \, du[/tex]

[tex]\int\limits^6_{-6} {(x + 4)\sqrt{36 - x^2}} \, dx = [-\frac{(36 - x^2)^\frac 32}{3}]|\limits^6_{-6} + 4\int\limits^6_{-6} 36\cos^2(u)}] \, du[/tex]

[tex]\int\limits^6_{-6} {(x + 4)\sqrt{36 - x^2}} \, dx = [-\frac{(36 - x^2)^\frac 32}{3}]|\limits^6_{-6} + 144\int\limits^6_{-6} \cos^2(u)} \, du[/tex]

When integrated, we have

[tex]\int\limits^6_{-6} {(x + 4)\sqrt{36 - x^2}} \, dx = -\frac{(36 - x^2)^\frac23}{3} + 2x\sqrt{36 - x^2} + 72\sin^{-1}(\frac{x}{6})[/tex]

Substitute in the boundaries and evaluate

So, we have

[tex]\int\limits^6_{-6} {(x + 4)\sqrt{36 - x^2}} \, dx = 72\pi[/tex]

Hence, the solution is 72π

The rational zeros of P(x) are -4/5, 1/2, and 5/2.The factored form of P(x) is (x + 4/5)(2x - 1)(2x - 5).

To find the possible rational zeros for the polynomial function P(x) = 10x³ + 17x² - 97x - 20, we can use the rational root theorem. According to the theorem, the possible rational zeros are given by the factors of the constant term (in this case, -20) divided by the factors of the leading coefficient (in this case, 10).

The factors of -20 are ±1, ±2, ±4, ±5, ±10, and ±20.

The factors of 10 are ±1, ±2, ±5, and ±10.

Combining these factors, we can write the possible rational zeros as follows: A. 1, 2, 5, 4, 10, 20, 1/2, 1/5, 1/10, 2/5, 4/5, 5/2

Therefore, the correct answer is (A).Next, to find the rational zeros of P(x), we can use synthetic division or polynomial long division to test each possible zero and check for any remainder. However, since the list of possible zeros is quite long, I will use a computer algebra system to find the rational zeros. Using a computer algebra system, we find that the rational zeros of P(x) = 10x³ + 17x² - 97x - 20 are: x = -4/5

x = 1/2

x = 5/2

Therefore, the rational zeros of P(x) are -4/5, 1/2, and 5/2.Finally, to factor P(x), we can use the found rational zeros and perform polynomial division. The quotient will be a quadratic polynomial. Let's perform the polynomial division:

(x + 4/5)(2x - 1)(2x - 5) = 10x³ + 17x² - 97x - 20

Therefore, the factored form of P(x) is (x + 4/5)(2x - 1)

45° is the measure of an angle that is coterminal with 405°

To find an angle that is coterminal with 405°, we need to subtract or add multiples of 360° until we get an angle within the range of 0° to 360°.

Starting with 405°, we can subtract 360° from it to bring it within the desired range.

405° - 360° = 45°

So, an angle that is coterminal with 405° is 45°.

Coterminal angles are angles that have the same initial and terminal sides but differ by a multiple of 360°. In other words, they point in the same direction but may complete more than one full revolution.

In this case, we are given the angle 405°. Since 360° represents one complete revolution, we can subtract 360° from 405° to find an angle that is coterminal within the range of 0° to 360°.

By subtracting 360° from 405°, we get 45°, which falls within the desired range. Therefore, 45° is the measure of an angle that is coterminal with 405°

Without any additional information about the lines or angles involved, it is not possible to determine if any lines are parallel based solely on the given information that ∠7 is congruent to ∠11 (represented as ∠7 ≅ ∠11).

The congruence of angles does not provide direct information about the parallelism of lines.

To determine if lines are parallel, additional information such as the relationships between specific angles and the lines they intersect would be necessary. Postulates and theorems related to parallel lines and angles, such as the corresponding angles postulate, alternate interior angles theorem, or consecutive interior angles theorem, would need to be considered.

Isaac will get approximately 9.46 quetzals for his 100 reais.

Given:

Spot rate on the GTQ/₡ cross rate: GTQ 10.5799 = ₡1.00

To find the Brazilian reais/Guatemalan quetzal cross rate:

GTQ/R$ = 1 / (GTQ/₡)

GTQ/R$ = 1 / 10.5799

GTQ/R$ = 0.09461

Therefore, the Brazilian reais/Guatemalan quetzal cross rate is approximately 0.0946.

To calculate how many quetzals Isaac will get for his reais, we need to multiply the number of reais by the cross rate.

Let's assume Isaac has 100 reais:

Quetzals = Reais * GTQ/R$

Quetzals = 100 * 0.0946

Quetzals = 9.46
