We note that c is a positively-oriented, smooth, simple closed curve. Green's theorem tells us that in this situation, if d is the region bounded by c, then p dx + q dy = (∂q/∂x - ∂p/∂y) dA

Based on the given information, we can apply Green's Theorem, which states that for a positively-oriented, smooth, simple closed curve c and the region d bounded by c, the line integral of the vector field (p, q) over c is equal to the double integral of the curl of (p, q) over d.

Green’s theorem is mainly used for the integration of the line combined with a curved plane. This theorem shows the relationship between a line integral and a surface integral.

It is related to many theorems such as Gauss theorem, Stokes theorem.

Green’s theorem is used to integrate the derivatives in a particular plane. If a line integral is given, it is converted into a surface integral or the double integral or vice versa using this theorem.

Green’s theorem is one of the four fundamental theorems of calculus, in which all of four are closely related to each other.

Green’s theorem defines the relationship between the macroscopic circulation of curve C and the sum of the microscopic circulation that is inside the curve C. Using the notation for the partial derivatives, we can express this as:

p dx + q dy = (∂q/∂x - ∂p/∂y) dA

Therefore, the missing terms in the equation would be q and p, respectively:
p dx + q dy = (∂q/∂x - ∂p/∂y) dA
p dx + q dy = (∂q/∂x - ∂p/∂y) dA
p dx + q dy = (∂q/∂x - ∂p/∂y) dA

Step-by-step explanation:

To calculate the amount of water needed to produce the beef consumed by one person in a more developed country per year, we need to first determine the amount of beef consumed per year and then multiply it by the water required to produce a given amount of beef.

The average person in a more developed country consumes 85 grams of beef per day. To find the annual consumption, we multiply this value by the number of days in a year:

Annual beef consumption = Daily beef consumption * Number of days in a year

Annual beef consumption = 85 grams/day * 365 days/year

Annual beef consumption = 31,025 grams/year

Now, we need to convert the beef consumption from grams to liters of water. It takes 1,750 liters of water to produce 113 grams of beef:

Water required per gram of beef = 1,750 liters / 113 grams

To calculate the total water needed per year, we multiply the water required per gram of beef by the annual beef consumption:

Water needed per year = Water required per gram of beef * Annual beef consumption

Water needed per year = (1,750 liters / 113 grams) * 31,025 grams/year

Calculating this value:

Water needed per year ≈ 480,496 liters/year

The Moon is a natural satellite of the Earth and it takes approximately 27.3 days to complete one rotation around its own axis.

The day and night cycles on the Moon are longer than those on Earth.

The reason for this difference in the length of day and night cycles is due to the Moon's synchronous rotation means that it takes the same amount of time for the Moon to complete one rotation around its own axis as it takes to complete one orbit around the Earth.

The synchronous rotation of the Moon is a result of the gravitational forces between the Earth and the Moon.

These forces have caused the Moon's rotation to gradually slow down over time, until it became synchronized with its orbit around the Earth.

As a result, the same side of the Moon always faces the Earth and the other side is permanently hidden from view.

The longer day and night cycles on the Moon have important implications for the lunar environment.

The extreme temperature variations between the day and night sides of the Moon make it a challenging environment for human exploration.

The daytime temperatures on the Moon can reach up to 127°C (261°F), while the nighttime temperatures can drop to -173°C (-280°F).

The Moon's day and night cycles are longer than those on Earth due to its synchronous rotation with its orbit around the Earth.

This unique phenomenon has important implications for the lunar environment and presents challenges for human exploration of the Moon.

The simplified expression of (7 + 12i) × (7 + 12i) is -95 + 168i.

To perform the indicated operation and simplify, we'll multiply the expression (7 + 12i) by itself

(7 + 12i) × (7 + 12i)

Using the distributive property, we can expand this expression

= 7 × (7 + 12i) + 12i × (7 + 12i)

= 49 + 84i + 84i + 144i²

Since i² is equal to -1, we can simplify further:

= 49 + 168i + 144(-1)

= 49 + 168i - 144

= -95 + 168i

Therefore, the simplified expression is -95 + 168i.

Answer:

y = 3x - 10

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 3 , thus

y = 3x + c ← is the partial equation

To find c substitute (1, - 7) into the partial equation

- 7 = 3 + c ⇒ c = - 7 - 3 = - 10

The function f is increasing on the interval (6, ∞).

The function f will be increasing in the intervals where f'(x) > 0.

To find these intervals, we can examine the sign of each factor of f'(x), which is (x + 1)²(x - 3)⁵(x - 6)⁴.

We can analyze the sign of f(x) by considering the factors individually:

(x+1)²: This factor is always positive since it is the square of a real number.

(x - 3)⁵: This factor is positive when x>3 and negative when x< 3.

(x - 6)⁴: This factor is positive when x>6 and  negative when x< 6.

We need to consider the overlapping regions of positivity for each factor.

When x>6, all three factors are positive, so  f ′ (x) is positive.

When 3<x<6: In this interval, the factor  (x+1)² is positive, but both (x−3)⁵ and (x−6)⁴ are negative.

Thus, f ′ (x) is negative.

When x<−1: In this interval,  (x+1)² is negative, while (x−3)⁵ and (x−6)⁴ are positive.

Hence, f ′ (x) is negative.

Therefore,  the function f(x) is increasing on the interval x>6.

The required sample size is 99 salespeople.

To estimate the population mean of travel days per year for salespeople with 98% confidence and a margin of error of 6 days, we need to determine the appropriate sample size. We can use the formula n = (z^2 * σ^2) / E^2, where n is the sample size, z is the z-score corresponding to the desired confidence level, σ is the standard deviation of the population (or sample, if known), and E is the desired margin of error. In this case, z = 2.33 (from the z distribution table for a 98% confidence level), σ = 32 (from the pilot study), and E = 6. Plugging these values into the formula gives us n = (2.33^2 * 32^2) / 6^2, which is approximately 98.68. We need to round this up to the next whole number, which is 99. Therefore, we should sample 99 salespeople to estimate the mean number of travel days per year for salespeople with 98% confidence and a margin of error of 6 days.

The derivative of the function f(x) = 2^x at the number α = 6 is given by the expression lim z->0 (2^x - 64) / (x - 6).

To find the derivative of the function f(x) = 2^x at α = 6, we use the definition of the derivative, which involves taking the limit of the difference quotient as x approaches α.

In this case, the expression lim z->0 (2^x - 64) / (x - 6) represents the difference quotient, where z is a small number that approaches zero. By substituting α = 6 into the expression, we have:

lim z->0 (2^6 - 64) / (6 - 6)

= (2^6 - 64) / 0

Here, we encounter an indeterminate form of division by zero. To determine the derivative, we need to apply a mathematical technique called L'Hôpital's rule, which allows us to evaluate limits involving indeterminate forms.

By differentiating the numerator and the denominator separately and taking the limit again, we can find the derivative of the function:

lim z->0 (2^x - 64) / (x - 6)

= lim z->0 (ln(2) * 2^x) / 1

= ln(2) * 2^6

= ln(2) * 64

Therefore, the derivative of the function f(x) = 2^x at α = 6 is ln(2) times 64, or simply 64ln(2).

In summary, the derivative of the function f(x) = 2^x at the number α = 6 is 64ln(2).

The Cantor's set is an example of a compact set of real numbers whose limit points form a countable set.

To construct a compact set of real numbers whose limit points form a countable set, we can utilize the concept of Cantor's set, which is a classic example of such a set.

Cantor's set is a compact set in which the limit points form a countable set. It is constructed by iteratively removing open intervals from a closed interval, resulting in a set with interesting properties.

Start with the closed interval [0, 1], representing the set of real numbers between 0 and 1 (inclusive).

Remove the open middle third of the interval, resulting in two closed intervals: [0, 1/3] and [2/3, 1].

Repeat the process for each remaining closed interval, removing the open middle third of each interval.

Continue this process infinitely, resulting in a set that consists of points that are not removed at any step.

The resulting set is the Cantor's set, which is compact and has the property that its limit points form a countable set.

c = (1/2) * ln[(1/3) * (e^(8) - e^(2) + 2)]

To find a value c in [1, 4] such that f(c) is equal to the average value of f(x) = e^(2x) + 1 on [1, 4], we need to use the Mean Value Theorem. The Mean Value Theorem states that if f is continuous on the closed interval [a,b] and differentiable on the open interval (a,b), then there exists a number c in (a,b) such that f'(c) = (f(b) - f(a))/(b-a).

First, we need to find the average value of f(x) on [1, 4]. The average value of a function on an interval [a,b] is given by:

Average value = (1/(b-a)) * ∫[a,b] f(x) dx

In this case, a = 1, b = 4, and f(x) = e^(2x) + 1. So the average value is:

Average value = (1/(4-1)) * ∫[1,4] (e^(2x) + 1) dx

= (1/3) * (e^(8) - e^(2) + 3)

Next, we need to find a value c in [1, 4] such that f(c) = average value. So we need to solve the equation:

e^(2c) + 1 = (1/3) * (e^(8) - e^(2) + 3)

Simplifying and rearranging terms gives us:

e^(2c) = (1/3) * (e^(8) - e^(2) + 2)

Taking the natural logarithm of both sides gives us:

2c = ln[(1/3) * (e^(8) - e^(2) + 2)]

Finally, we can solve for c:

c = (1/2) * ln[(1/3) * (e^(8) - e^(2) + 2)]

This is the value of c in [1, 4] such that f(c) is equal to the average value of f(x) on [1, 4].

Answer:

x = 3 or x = -3

Step-by-step explanation:

Solve for x over the real numbers:

2 x (x + 3) - 6 (x + 3) = 0

Expand out terms of the left hand side:

2 x^2 - 18 = 0

2 x^2 - 18 = 2 (x^2 - 9):

2 (x^2 - 9) = 0

Divide both sides by 2:

x^2 - 9 = 0

x = (0 ± sqrt(0^2 - 4 (-9)))/2 = ( ± sqrt(36))/2:

x = sqrt(36)/2 or x = (-sqrt(36))/2

sqrt(36) = sqrt(4×9) = sqrt(2^2×3^2) = 2×3 = 6:
