A large corporation with monopolistic control in the marketplace has its average daily costs, in dollars, given by 900 + 100x + x2 C = X = 180,000 – 50x dollars. Find the quantity that gives maximum profit

Answer:

18:19

Step-by-step explanion:
To solve this problem, we need to first calculate the time it takes for the plane to fly from Singapore to Sydney:

Time = Distance ÷ Speed

Time = 6310 km ÷ 757.2 km/h

Time ≈ 8.34 hours

This is the time it takes to fly from Singapore to Sydney in Singapore time. However, we need to convert this time to Sydney time, which is 2 hours ahead of Singapore time. Therefore, the local time when the plane arrives in Sydney is:

Time in Sydney = Singapore time + 2 hours + Flight time

Time in Sydney = 07:45 + 2 hours + 8.34 hours

Time in Sydney = 18:19

Therefore, the local time when the plane arrives in Sydney is 18:19 using the 24-hour clock.

The sum of all the terms in the arithmetic progression is 3507.

The common difference in an arithmetic progression is the difference between any two consecutive terms. Let the common difference be d. Then, the third term is 2 + d, the fourth term is 2 + 2d, and so on. Also, let the last term be n.

Since the last term is greater than 150, we can write n = 2 + (n-2)d > 150. Solving this inequality, we get d < 74. Therefore, the common difference can be 1, 2, 3, ..., 73.

Using the formula for the sum of an arithmetic progression, we get the sum of all the terms as (n/2)(first term + last term) = (n/2)(2 + n d) = (n/2)(11 + (n-1)d).

We can substitute n = (last term - first term)/d + 1 and solve for the sum. This gives us the final answer of 3507.

The value of the segment IH for the circle with secant through H which intersect the circle at points I and J is (6 + 2i√7) or (6 - 2i√7)

Circle theorems are a set of rules that apply to circles and their constituent parts, such as chords, tangents, secants, and arcs. These rules describe the relationships between the different parts of a circle and can be used to solve problems involving circles.

GH² = IH × JI {secant tangent segments}

JI = 12 - IH, we shall represent IH with x so that;

8² = x(12 - x)

64 = 12x - x²

x² - 12x + 64 = 0 {rearrange to get a quadratic equation}

with the quadratic formula;

x = [12 + √(-112)]/2 or x = = [12 - √(-112)]/2

√(-112) = 4i√7 {where i = √(-1)}

so;

x = (6 + 2i√7) or x = (6 - 2i√7)

The perimeter, P, of the hexagon in terms of x is 18x + 24.

To find the perimeter, P, of the hexagon in terms of x, we'll consider the given side lengths.

The hexagon has 4 sides of length 3x + 5. The other 2 sides are each 3 units shorter than the other 4 sides, so their length is (3x + 5) - 3 = 3x + 2.

Now, we can calculate the perimeter by adding the lengths of all 6 sides:

P = (4 * (3x + 5)) + (2 * (3x + 2))

First, distribute the numbers to the expressions inside the parentheses:

P = (12x + 20) + (6x + 4)

Next, combine like terms:

P = 18x + 24

The dealer bought 42 radios.

Let x be the number of radios the dealer bought.

Let y be the price the dealer paid for each radio.

We know that the dealer bought x radios for a total of $1,008, so:

x * y = 1008

We also know that the dealer gave away 6 radios and sold the rest for $14 more than she paid for each radio, breaking even. This means that the total revenue from selling the remaining radios is equal to the total cost of buying them:

(x - 6) * (y + 14) = x * y

Simplifying this equation, we get:

xy + 14x - 6y - 84 = xy

14x - 6y = 84

7x - 3y = 42 (dividing by 2 on both sides)

Now we have two equations:

x * y = 1008

7x - 3y = 42

We can use substitution or elimination to solve for x and y. Let's use elimination by multiplying the second equation by y/3 and adding it to the first equation:

x * y + (7x - 3y) * (y/3) = 1008 + 42 * (y/3)

xy + 7xy/3 - y²/3 = 1008 + 14y

10xy/3 - y²/3 - 14y - 1008 = 0

Multiplying both sides by 3, we get:

10xy - y² - 42y - 3024 = 0

Now we can use the quadratic formula to solve for y:

y = (-b ± sqrt(b² - 4ac)) / 2a

where a = -1, b = -42, and c = -3024:

y = (-(-42) ± sqrt((-42)² - 4(-1)(-3024))) / 2(-1)

y = (42 ± sqrt(42² - 4*3024)) / 2

y = (42 ± 126) / 2

y = 84 or y = -42

Since the price of a radio cannot be negative, we can discard the second solution and conclude that y = 84.

Now we can solve for x using the first equation:

x * y = 1008

x * 84 = 1008

x = 12

Therefore, the dealer bought 12 radios.

When separating 4,780 castings into 25 piles, there will be 5 castings left over.

A fraction is a numerical expression representing a part of a whole. It consists of a numerator (the top number) that indicates how many parts are considered, and a denominator (the bottom number) that shows the total number of equal parts in the whole. Fractions are typically expressed as a/b, where "a" is the numerator and "b" is the denominator. They are used in various mathematical operations, including addition, subtraction, multiplication, and division, and in real-life scenarios involving proportions and portions.

In order to determine the number of castings left over when separating 4,780 castings into 25 piles, we can use division. Divide 4,780 by 25 to find the number of castings in each pile.

The quotient is 191.2. Since we can't have a fraction of a casting, we round down to 191.

To find the number of castings left over, subtract the total number of castings in the piles from the original total. 4,780 - (191 x 25)

= 4,780 - 4,775

= 5

Therefore, when you complete the job, you will have 5 castings left over.

The calculated value of the expression A/the area of XYZ is [tex]\frac{49\sqrt3}{216}[/tex]

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

By the ratio of corresponding sides (see attachment for figure), we have

(x + 2y)/(2x + y) = 3/4

By comparison, we have

x + 2y = 3

2x + y = 4

This gives

(x, y) = (5/3, 2/3)

The triangles are equilateral triangles

So, we have

Area of XYZ = 1/2 * side length² * sin(60)

This gives

Area of XYZ = 1/2 * (2x + y)² * sin(60)

Substitute the known values in the above equation

Area of XYZ = 1/2 * (4)² * sin(60)

Evaluate

Area of XYZ = 4√3

The region A is a trapezoid

So, the area is

A = 1/2 * Sum of parallel sides * height

So, we have

A = 1/2 * (x + y) * (x² - y²)

Recall that (x, y) = (5/3, 2/3)

So, we have

A = 1/2 * (5/3 + 2/3) * ((5/3)² - (2/3)²)

Evaluate

A = 49/18

Finding A/the area of XYZ, we have

A/the area of XYZ = 49/18 ÷ 4√3

The first minimum payment would be $62.40 as it is higher than $25.

To determine the first minimum payment for a $3000 balance transfer at 4.99% with a 4% fee, you need to first calculate the balance transfer fee and add it to the initial balance. Then, you'll need to determine the minimum payment based on the credit card issuer's policy.

1. Calculate the balance transfer fee: $3000 * 4% = $120
2. Add the balance transfer fee to the initial balance: $3000 + $120 = $3120
3. The minimum payment depends on the credit card issuer's policy. Typically, the minimum payment is a percentage of the balance or a fixed amount, whichever is higher. For example, if the issuer requires a minimum payment of 2% of the balance or $25, whichever is higher:
  - Calculate 2% of the balance: $3120 * 2% = $62.40
  - Since $62.40 is higher than $25, the first minimum payment would be $62.40.

div(F) = ∇ · F = ∂(yz)/∂x + ∂(-5xz)/∂y + ∂(-4xy)/∂z

= 0 - 5z - 4x

= -5z - 4x

To find the curl of F, we need to take the cross product of the del operator with F. Therefore, we have:

curl(F) = ∇ × F = ( ∂(-4xy)/∂y - ∂(-5xz)/∂z, ∂(yz)/∂z - ∂(4xy)/∂x, ∂(-yz)/∂x - ∂(-5xz)/∂y )

The correct equation to predict the number of years it would take for the painting to have a value of $10,000 is 15,000(0.85)[tex]^{(t)}[/tex] = 10,000. The correct answer is option (c).

The initial value of the painting is $15,000, and its value is predicted to decay by 15% each year. This means that its value after t years can be represented by the equation:

V(t) = 15,000(0.85)[tex]^{(t)}[/tex]

We want to find the number of years it would take for the value to reach $10,000, so we set V(t) equal to 10,000 and solve for t:

10,000 = 15,000(0.85)[tex]^{(t)}[/tex]

Dividing both sides by 15,000 gives:

0.6667 = 0.85[tex]^{(t)}[/tex]

Taking the natural logarithm of both sides gives:

ln(0.6667) = t ln(0.85)

Solving for t gives:

t = ln(0.6667) / ln(0.85) = 2.294

So it would take approximately 2.294 years for the painting to have a value of $10,000. The right option is (c).

The four possible decodings of the ciphertext c = 823 845 737 are 156276219, 561472502, 1188260592, and 197895457.

To encode the plaintext m = 414 892 055, we first need to compute the corresponding ciphertext c using the Rabin cryptosystem.

The Rabin cryptosystem involves four steps: key generation, message encoding, message decoding, and key decryption. Since we already have the key n, we can skip the key generation step.

To encode the message m, we compute:

c ≡ m^2 (mod n)

Substituting the given values, we get:

c ≡ 414892055^2 (mod 1359692821)

c ≡ 1105307085 (mod 1359692821)

Therefore, the encoded ciphertext is c = 1105307085.

(b) To find the four decodings of the ciphertext c = 823 845 737, we need to use the Rabin cryptosystem to compute the four possible square roots of c modulo n.

First, we need to factorize n as n = 32359 · 42019. Then we compute the two square roots of c modulo each of the two prime factors, using the following formula:

x ≡ ± [tex]y^((p+1)/4) (mod p)[/tex]

where x is the square root of c modulo p, y is a solution to the congruence y^2 ≡ c (mod p), and p is one of the prime factors of n.

For the first prime factor p = 32359, we can use the following values:

y ≡ 3527^2 (mod 32359) ≡ 15467 (mod 32359)

x ≡ ± y^((p+1)/4) (mod p) ≡ ± 6692 (mod 32359)

Therefore, the two possible square roots of c modulo 32359 are 6692 and 25667.

For the second prime factor p = 42019, we can use the following values:

y ≡ 3527^2 (mod 42019) ≡ 25058 (mod 42019)

x ≡ ± y^((p+1)/4) (mod p) ≡ ± 1816 (mod 42019)

Therefore, the two possible square roots of c modulo 42019 are 1816 and 40203.

To find the four possible decodings of the ciphertext c = 823 845 737, we combine each of the two possible square roots modulo 32359 with each of the two possible square roots modulo 42019, using the Chinese Remainder Theorem:

x ≡ a (mod 32359)

x ≡ b (mod 42019)

where a and b are the two possible square roots modulo 32359 and 42019, respectively.

The four possible values of x are:

x ≡ 156276219 (mod 1359692821)

x ≡ 561472502 (mod 1359692821)

x ≡ 1188260592 (mod 1359692821)

x ≡ 197895457 (mod 1359692821)

Therefore, the four possible decodings of the ciphertext c = 823 845 737 are 156276219, 561472502, 1188260592, and 197895457.

Let's assume that there are three brothers, including Musa. Let X be the amount of money that the brother with the highest average takes, and let Y be the amount of money that the brother with the third rank takes.

According to the given conditions, we can write the following equations:

Let's simplify equation 1:

X + Y = 2900

Also, we know that:

X = (2Y + X)/2

(The amount that the third rank takes is half of what the first rank takes)

Simplifying this equation:

2X = 2Y + X

X = 2Y

Substituting this value of X in equation X + Y = 2900:

3Y = 2900

Y = 2900/3

Y ≈ 966.67

As the amount given must be a whole number between two consecutive natural numbers, we can round Y to the nearest natural number:

Y = 967

Then, X = 2Y = 2*967 = 1934

[tex]tan(1/2 * theta) = ±√5 - 1[/tex]

Since theta is in the first quadrant, tan(1/2 * theta) is positive. Therefore:

[tex]tan(1/2 * theta) = √5 - 1[/tex]

We can simplify this expression by rationalizing the denominator:

[tex]tan(1/2 * theta) = (√5 - 1) / (√5 + 1) * (√5 - 1) / (√5 - 1)[/tex]

[tex]tan(1/2 * theta) = (5 - 2√5)[/tex]

So the answer is (5 - 2√5), which is approximately 0.382. Therefore, the answer is not one of the choices given.

If 5 out of every 24 players were repaired during the first year of ownership, then 200 of the 960 DVD players were repaired in the first year.

Based on the manufacturer's records, we know that 5 out of every 24 players were repaired in the first year of ownership. To find out how many out of the 960 DVD players were repaired in the first year, we can set up a proportion:

5/24 = x/960

To solve for x, we can cross-multiply:

5 * 960 = 24x

4800 = 24x

x = 200

Therefore, 200 of the 960 DVD players were repaired in the first year, which is approximately 20.8% of the total shipped.
