Consider the following nonlinear programming problem. Maximize f(x₁, x₂) = x1/² x 1/² 1/2 1/2 Subject to4 x₁ + 2x₂ ≤ 10 and X₁ > 0, x₂ > 0 (a) Determine whether the problem is a convex programming problem. (b) Write down the KKT conditions for this problem. (c) Determine a possible solution to the problem.

the estimated cost of manufacturing the 321st pair of shoes is approximately 2000 dollars.

(a) The units of f'(x) are the derivative of the cost function, C = f(x), with respect to the number of pairs of shoes, x. Since C is measured in dollars and x is measured in pairs of shoes, the units of f'(x) will be dollars per pair of shoes. Units: dollars/pair
(b) To estimate the cost of manufacturing an additional pair of shoes when you've already manufactured 320 pairs, we can use the given derivative value, f'(320) = 2000. Since f'(x) represents the rate of change of the cost with respect to the number of pairs, f'(320) = 2000 tells us that at 320 pairs, the cost is increasing by 2000 dollars for each additional pair.

There is no combination of operation signs that can be placed in the equation "3 7 12 2 = 15" to make it true with the given numbers.

To make the equation "3 7 12 2 = 15" true by placing the operation signs in the correct places, we need to determine the appropriate operations between the numbers.

Let's analyze the given numbers and the desired result.

Given: 3 7 12 2 = 15

To reach a sum of 15, we can observe that 12 - 7 = 5, and 5 + 2 = 7. Therefore, we can construct the equation as follows:

3 + 7 - 12 + 2 = 15

In this arrangement, we start with addition by adding 3 and 7 to get 10. Then, we subtract 12 to obtain -2.

We add 2 to reach a total of 0.

Although this does not match the desired result of 15, we can use multiplication or exponentiation to manipulate the numbers further.

To achieve a sum of 15, we can employ exponentiation:

3² + 7 - 12 + 2 = 15

In this modified equation, we square 3 to obtain 9, which, when added to 7, equals 16.

We then subtract 12 and add 2 to yield a total of 6.

Unfortunately, this still does not result in the desired value of 15.

Given the limited set of operations available (addition, subtraction, multiplication and exponentiation), it seems impossible to form an equation using the provided numbers that will evaluate to 15.

It is worth noting that other mathematical operations, such as square roots or factorial, are not available for this particular exercise.

The correct choice for setting a fixed number of decimal places is option a) decimal places.

The "decimal places" formatting property of a control allows you to set a fixed number of decimal places to display for numerical values.

It is commonly used when dealing with numbers that require a specific level of precision or when you want to restrict the number of decimal places shown to the user.

By setting the "decimal places" property to a specific value, such as 2, you can ensure that the control will always display the number with two decimal places. This is particularly useful in financial or scientific applications where accuracy is important and consistent formatting is desired.

The other options, b) visible, c) back color, and d) fore color, are not related to setting a fixed number of decimal places. The "visible" property determines whether the control is visible or hidden,

while the "back color" and "fore color" properties deal with the background and foreground colors of the control, respectively. Therefore, the correct choice for setting a fixed number of decimal places is option a) decimal places.

The 14C:12C ratio can be used to date fossils that are up to approximately 50,000 years old. This is because the half-life of carbon-14 (14C) is about 5,730 years, which limits its effective dating range.

In summary, the 14C:12C ratio is used to date fossils that are up to approximately 50,000 years old due to the half-life of carbon-14 (14C).

Carbon-14 is a radioactive isotope of carbon that is formed in the upper atmosphere through the interaction of cosmic rays with nitrogen-14. It is incorporated into the carbon cycle and taken up by living organisms through photosynthesis or consumption of other organisms. While an organism is alive, the 14C:12C ratio remains relatively constant. However, once the organism dies, it no longer takes in carbon-14, and the 14C atoms in its remains undergo radioactive decay. By measuring the 14C:12C ratio in a fossil sample and comparing it to the 14C:12C ratio in the atmosphere at the time of death, scientists can estimate the age of the fossil. However, the effectiveness of carbon-14 dating diminishes as the age of the sample exceeds around 50,000 years, as the amount of remaining carbon-14 becomes too small to accurately measure.

we can use the method of undetermined coefficients. Let's start by finding the complementary solution to the homogeneous equation:

Using the quadratic formula, we find the roots:

r = (-2 ± sqrt(2^2 - 4*1*5)) / (2*1)

  = (-2 ± sqrt(-16)) / 2

  = (-2 ± 4i) / 2

  = -1 ± 2i.

Therefore, the complementary solution is:

y_c(t) = e^(-t) * (c1*cos(2t) + c2*sin(2t)).

Now, let's find the particular solution for the non-homogeneous equation using undetermined coefficients. Since we have e^(-t) * cos(2t) in the right-hand side, we assume the particular solution has the form:

y_p(t) = (A*t + B) * e^(-t) * cos(2t) + (C*t + D) * e^(-t) * sin(2t).

Now, we'll differentiate y_p(t) twice to find the derivatives needed for the equation:

y_p'(t) = [(-A*t - B + A - 2B*t)*e^(-t) + (A*t + B)*(-e^(-t))]*(cos(2t))

         + [(C*t + D - C - 2D*t)*e^(-t) + (C*t + D)*(-e^(-t))]*(sin(2t))

       = [(A - B + (A - 2B)*t)*e^(-t) - (A*t + B)*e^(-t)]*cos(2t)

         + [(C - D + (C - 2D)*t)*e^(-t) - (C*t + D)*e^(-t)]*sin(2t)

       = [(2A - 3B + (2A - 4B)*t)*e^(-t)]*cos(2t)

         + [(2C - 3D + (2C - 4D)*t)*e^(-t)]*sin(2t).

y_p''(t) = [((2A - 4B)*e^(-t) + (2A - 4B)*e^(-t) + (2A - 4B)*e^(-t) - (2A - 4B)*e^(-t)*t)*cos(2t)

         - (2A - 4B)*e^(-t)*cos(2t)]

         - (2C - 4D)*e^(-t)*sin(2t)]

       = [8B*e^(-t)*t*cos(2t) - 4B*e^(-t)*cos(2t)]

         + [8D*e^(-t)*t*sin(2t) - 4D*e^(-t)*sin(2t)]

Without the specific values of f(x) and f'(x) at x = 4, we cannot calculate the exact value of ∫40xf′(x)dx. ∫40xf′(x)dx = x∫f′(x)dx - ∫f(x)dx

= x[f(x)]|₀⁴ - ∫f(x)dx       = 4f(4) - 8.

To find the value of ∫40xf′(x)dx, we can use integration by parts. The formula for integration by parts is:

∫u dv = uv - ∫v du,

where u and v are functions of x.

Let's apply this formula to the integral in question, where u = x and dv = f'(x)dx:

∫40xf′(x)dx = x∫f′(x)dx - ∫(∫f′(x)dx) dx.

The second term on the right side of the equation can be simplified as follows:

∫(∫f′(x)dx) dx = ∫f(x)dx.

Now, we can rewrite the integral as:

∫40xf′(x)dx = x∫f′(x)dx - ∫f(x)dx.

Since f(x) is given in the table, we can calculate ∫f(x)dx by integrating the values of f(x) over the interval [0, 4].

∫f(x)dx = ∫40f(x)dx = 8.

Therefore, the value of ∫40xf′(x)dx can be expressed as:

∫40xf′(x)dx = x∫f′(x)dx - ∫f(x)dx

= x[f(x)]|₀⁴ - ∫f(x)dx

= 4f(4) - 8.

To determine the value of ∫40xf′(x)dx, we need the value of f(4), which is not provided in the question. Without knowing the specific values of f(x) and f'(x) at x = 4, we cannot calculate the exact value of ∫40xf′(x)dx.

(a) To generate an exponential random variable with parameter lambda = 2.5 using a standard uniform random variable U, we can use the inverse transform method. The inverse of the cumulative distribution function (cdf) of an exponential distribution is given by:

F^(-1)(U) = -ln(1 - U) / lambda

Therefore, to generate an exponential random variable X with parameter lambda = 2.5, we can compute:

X = -ln(1 - U) / 2.5

If U = 0.3972, then:

X = -ln(1 - 0.3972) / 2.5 = 0.3146

(b) To generate a Bernoulli random variable with probability of success p = 0.77 using a standard uniform random variable U, we can use the following algorithm:

   Generate U from a standard uniform distribution.

   If U is less than p, set the Bernoulli random variable to 1 (success); otherwise, set it to 0 (failure).

If U = 0.3972 and p = 0.77, then:

Since U < p, the Bernoulli random variable is 1 (success).

(c) To generate a binomial random variable with parameters n = 15 and p = 0.4 using a standard uniform random variable U, we can use the following algorithm:

   Generate U from a standard uniform distribution.

   If U is less than p, count the trial as a success; otherwise, count it as a failure.

   Repeat steps 1 and 2 for a total of n trials.

   The binomial random variable is the number of successes.

If U = 0.3972 and n = 15, p = 0.4, then:

   First trial: U > p, count as a failure.

   Second trial: U < p, count as a success.

   Third trial: U < p, count as a success.

   Fourth trial: U > p, count as a failure.

   Fifth trial: U > p, count as a failure.

   Sixth trial: U > p, count as a failure.

   Seventh trial: U > p, count as a failure.

   Eighth trial: U < p, count as a success.

   Ninth trial: U > p, count as a failure.

   Tenth trial: U > p, count as a failure.

   Eleventh trial: U > p, count as a failure.

   Twelfth trial: U < p, count as a success.

   Thirteenth trial: U > p, count as a failure.

   Fourteenth trial: U > p, count as a failure.

   Fifteenth trial: U < p, count as a success.

Therefore, the binomial random variable is 5 (number of successes).

(d) To generate a discrete random variable with distribution P(x), where P(0) = 0.2, P(2) = 0.4, P(7) = 0.3, P(11) = 0.1 using a standard uniform random variable U, we can use the following algorithm:

   Generate U from a standard uniform distribution.

   If U is less than P(0), set the random variable to 0; otherwise, check the next interval.

   If U is less than P(0) + P(2), set the random variable to 2; otherwise, check the next interval.

   If U is less than P(0) + P(2) + P(7), set the random variable to 7; otherwise, set it to 11.

If U = 0.3972, then:

First, we need to compute the cumulative probabilities for the distribution:

   P(0) = 0.2

   P(2) = 0.2 + 0.4 = 0.6

   P(7) = 0.6 + 0.3 = 0.9

   P(11) = 0.9 + 0.1 = 1.0

Since U is between 0.6 and 0.9, the random variable is 7.

(e) To generate a continuous random variable with the density f(x) = 3x^2, 0 < x < 1 using a standard uniform random variable U, we can use the inverse transform method. The cumulative distribution function of the continuous random variable is:

F(x) = ∫0x f(t) dt = x^3

Solving for x in terms of U, we get:

U = F(x) = x^3

x = U^(1/3)

If U = 0.3972, then:

x = 0.3972^(1/3) = 0.7269

Therefore, the continuous random variable is approximately 0.7269.

(f) To generate a continuous random variable with the density f(x) = 1.5x^2, -1 < x < 1 using a standard uniform random variable U, we can use the following algorithm:

   Generate U from a standard uniform distribution.

   If U is less than 0.5, set the random variable to [tex]sqrt(U/1.5)[/tex]- 1; otherwise, set it to 1 - [tex]sqrt((1 - U)/1.5).[/tex]

If U = 0.3972, then:

Since U < 0.5, the random variable is:

[tex]sqrt(0.3972/1.5) - 1 = -0.1024[/tex]

(g) To generate a continuous random variable with the density f(x) = |x|, -1 < x < 1 using a standard uniform random variable U, we can use the following algorithm:

   Generate U from a standard uniform distribution.

   If U is less than 0.5, set the random variable to [tex]sqrt(2U) - 1;[/tex] otherwise, set it to [tex]1 - sqrt(2(1 - U)).[/tex]

If U = 0.3972, then:

Since U < 0.5, the random variable is:

[tex]sqrt(2(0.3972)) - 1 = 0.2399[/tex]

Thus, if M = $1.5 trillion, V = 7, and P = 1.05, the real output of the economy (Q) is $10 trillion.

The equation of exchange is an economic equation that relates the money supply (M) with the price level (P), the velocity of money (V), and the real output of the economy (Q). The equation is M x V = P x Q.

Using the given values of M = $1.5 trillion, V = 7, and P = 1.05, we can solve for Q by rearranging the equation as Q = M x V / P.

Plugging in the numbers, we get:

Q = ($1.5 trillion x 7) / 1.05 = $10 trillion

Therefore, if M = $1.5 trillion, V = 7, and P = 1.05, the real output of the economy (Q) is $10 trillion.

It's worth noting that the equation of exchange is a theoretical model and may not reflect actual economic conditions. In practice, changes in any one of the variables (M, V, P, or Q) can affect the others, and there may be other factors at play that influence the economy.

To determine how many stars we would have to search before expecting to hear a signal from the 10,000 civilizations broadcasting radio signals in the Milky Way Galaxy, we can calculate the average number of stars each civilization would be associated with.

Assuming there are 500 billion stars in the galaxy, we divide this number by the total number of civilizations:

Average number of stars per civilization = Total number of stars / Total number of civilizations = 500 billion / 10,000 = 50 million stars

Therefore, on average, we would have to search approximately 50 million stars before expecting to hear a signal from one of the 10,000 civilizations.

If there were only 100 civilizations instead of 10,000, we would need to recalculate the average number of stars per civilization:

Average number of stars per civilization = Total number of stars / Total number of civilizations = 500 billion / 100 = 5 billion stars

In this case, we would have to search approximately 5 billion stars on average before expecting to hear a signal from one of the 100 civilizations.

(b) The new position of the kite is approximately 43.3 feet away from the original position.

(a) To find the magnitude and direction of the vector from the kite to the ground, we can use trigonometry. The magnitude is given as 50 feet, which is the length of the string. The angle between the string and the ground is 20 degrees. Since the angle is measured above the horizontal, we subtract it from 90 degrees to find the direction. Thus, the direction is 70 degrees above the horizontal.

(b) When the wind blows the kite upward and changes its angle with the ground to 40 degrees, we can consider the new position as the vertical component of the original position. Using trigonometry, we can find the distance of the new position from the original position. The vertical component is given by 50 feet times the sine of 40 degrees, which is approximately 32.3 feet. The horizontal component remains the same as the original position, which is 50 feet times the cosine of 40 degrees, approximately 38.7 feet.

Main Answer:The circumstances under which the shape of the sampling distribution of pn is approximately normal.

Supporting Question and Answer:

What is the Central Limit Theorem and how does it relate to the shape of the sampling distribution of pn?

The Central Limit Theorem states that, under certain conditions, the sampling distribution of the sample mean (or sum) approaches a normal distribution as the sample size increases, regardless of the shape of the population distribution. This theorem is applicable to the sampling distribution of pn (proportion) because the proportion can be considered as the sample mean of a binary variable (success or failure). As the sample size increases, the Central Limit Theorem ensures that the sampling distribution of pn becomes more approximately normal, making it a useful approximation for making inferences about the population proportion.

Body of the Solution:The shape of the sampling distribution of pn (proportion) is approximately normal under certain circumstances. These circumstances are related to the properties of the population being sampled and the sample size. Here are the key factors:

1.Large sample size: The sampling distribution of pn tends to become more approximately normal as the sample size increases. This is known as the Central Limit Theorem. As the sample size grows larger, the distribution of sample proportions approaches a normal distribution regardless of the shape of the population distribution.

2.Random sampling: The sample should be selected randomly from the population to ensure that each member of the population has an equal chance of being included in the sample. Random sampling helps to ensure that the sample is representative of the population.

3.Independence assumption: The sampled observations should be independent of each other. This means that the selection of one observation should not influence the selection or behavior of other observations. Independence is crucial to ensure that the sampling distribution accurately reflects the population distribution.

4.Adequate population size: If the population size is sufficiently large,

relative to the sample size, the shape of the sampling distribution of pn is approximately normal. In practice, if the population is at least 10 times larger than the sample size, this condition is considered to be met.

5.Binomial distribution approximation: The shape of the sampling distribution of pn is also approximately normal when the underlying population distribution follows a binomial distribution. The binomial distribution is characterized by a fixed number of trials and two possible outcomes (success or failure) for each trial.

Final Answer: These circumstances increase the likelihood of the sampling distribution of pn being approximately normal, it does not guarantee it in all cases. In practice, checking the normality of the sampling distribution can be done using statistical tests or graphical methods, such as a histogram or a normal probability plot.

To show that E(X1+ X2 + .... XN)= µE(N), we need to use the law of total expectation, also known as the law of iterated expectations.

First, we can write the expected value of X1+ X2 + .... XN as:
E(X1+ X2 + .... XN) = E(E(X1+ X2 + .... XN | N))

Here, we are conditioning on the value of N. This means that we are taking the expected value of X1+ X2 + .... XN, given a specific value of N.

Next, we can use the fact that the X's are identically distributed with mean µ. This means that:
E(X1) = E(X2) = ... = E(XN) = µ

Using this, we can rewrite the expected value of X1+ X2 + .... XN, conditioned on N, as:
E(X1+ X2 + .... XN | N) = E(X1 | N) + E(X2 | N) + ... + E(XN | N)
= µ + µ + ... + µ (N times)
= Nµ

Now, substituting this back into the expression for E(X1+ X2 + .... XN) that we wrote earlier, we get:
E(X1+ X2 + .... XN) = E(E(X1+ X2 + .... XN | N))
= E(Nµ)
= µE(N)

This completes the proof. We have shown that E(X1+ X2 + .... XN)= µE(N), by conditioning on the value of N and using the fact that the X's are identically distributed with mean µ.

The mean is a measure of central tendency that calculates the average of a set of values. It is often considered the most precise measure because it takes into account all the values in the dataset and provides a balanced representation.

The mean is calculated by summing all the values and dividing by the total number of values. Unlike the mode, which only identifies the most frequently occurring value, and the median, which represents the middle value, the mean incorporates all the values and provides a comprehensive summary of the dataset.

To find a polynomial function with integer coefficients that has the given zeros, we can use the factor theorem and the zero-product property. Therefore, the function is f(x) = (x + 2)(x - 1)(x - 3) = x^3 - 2x^2 - 5x + 6 .

In summary, to find a polynomial function with integer coefficients that has the given zeros, we can use the factor theorem and the zero-product property to obtain the factors of the polynomial, and then multiply them together to get the polynomial function.

For example, suppose we want to find a polynomial function with integer coefficients that has zeros at -2, 1, and 3. We can start by using the factor theorem to obtain the factors of the polynomial:

(x + 2)(x - 1)(x - 3)

We can then multiply these factors together to obtain the polynomial function:

f(x) = (x + 2)(x - 1)(x - 3) = x^3 - 2x^2 - 5x + 6

This is a polynomial function with integer coefficients that has zeros at -2, 1, and 3. Note that we can also check this by using the zero-product property, which states that if a product of factors is equal to zero, then at least one of the factors must be zero. We can plug in each of the zeros (-2, 1, and 3) into the polynomial function and verify that the result is zero, which confirms that these are indeed the zeros of the polynomial.

The rotational kinetic energy of the flywheel is  572,819 J.

The flywheel you described has a radius of 1.58 m and a mass of 91.6 kg. It is spinning counterclockwise at 477 rpm. This means it has a certain amount of rotational kinetic energy, which is proportional to both its mass and its speed of rotation. The formula for rotational kinetic energy is 1/2*I*w^2, where I is the moment of inertia (a measure of how spread out the mass is in the object) and w is the angular velocity (the speed of rotation in radians per second).

To find the moment of inertia of the disk, we can use the formula I = 1/2*m*r^2, where m is the mass and r is the radius. Plugging in the values given, we get I = 1/2*91.6 kg*(1.58 m)^2 = 228.6 kg*m^2.

To convert the rotational speed from rpm to radians per second, we need to multiply by 2*pi/60. So, w = 477 rpm * 2*pi/60 = 50.04 rad/s.

Using these values, we can calculate the rotational kinetic energy of the flywheel as 1/2*(228.6 kg*m^2)*(50.04 rad/s)^2 = 572,819 J.

We can substitute the function into the differential equation and solve for the values of r. The resulting characteristic equation will determine the values of r that satisfy the given differential equation.

To determine the values of r for which the function y = e^(rx) satisfies the differential equation 3y'' + 8y' - 3y = 0, we substitute y = e^(rx) into the differential equation:

3(e^(rx))'' + 8(e^(rx))' - 3(e^(rx)) = 0

Next, we differentiate y = e^(rx) twice and substitute into the equation:

3r^2e^(rx) + 8re^(rx) - 3e^(rx) = 0

Factoring out e^(rx) gives:

e^(rx)(3r^2 + 8r - 3) = 0

For this equation to hold true, either e^(rx) = 0 (which is not possible) or the expression inside the parentheses must equal zero:

3r^2 + 8r - 3 = 0

We can solve this quadratic equation to find the values of r. Once we solve for r, we can identify the two distinct values, which can be denoted as r = (smaller value) and r = (larger value). These values of r will satisfy the given differential equation when substituted into the function y = e^(rx).

The closed interval for this application is [0, 24].

In this scenario, let's consider the function f(t) to represent the distance traveled by the ancient warship after t hours. We are given that the ship covered 168 sea miles in 24 hours, so we have f(24) - f(0) = 168.

We want to show that at some point during this feat, the ship's speed exceeded 6.6 knots (sea miles per hour), which means we need to prove that there exists a point c in the interval (0, 24) where the instantaneous rate of change of distance, f'(c), exceeds 6.6.

Using the Mean Value Theorem, we have:

f'(c) = (f(24) - f(0)) / (24 - 0)

Since f(24) - f(0) = 168, we can simplify the equation:

f'(c) = 168 / 24

= 7

Therefore, according to the Mean Value Theorem, there exists a point c in the interval (0, 24) where the instantaneous rate of change of distance, or the ship's speed, f'(c), equals 7 knots. Since 7 knots is greater than 6.6 knots, we can conclude that at some point during the 24-hour feat, the ship's speed exceeded 6.6 knots. Therefore, the closed interval for this application is [0, 24].

The given geometric series ∑[infinity]n=16(0.7)n−1 is convergent. To find the sum of a convergent geometric series, we can use the formula:

S = a / (1 - r),

To determine if a geometric series converges or diverges, we need to examine the common ratio (r) of the series. In this case, the common ratio is 0.7. For a geometric series to converge, the absolute value of the common ratio must be less than 1.

In this case, |0.7| = 0.7, which is less than 1. Therefore, the geometric series converges.

To find the sum of a convergent geometric series, we can use the formula:

S = a / (1 - r),

where "a" represents the first term and "r" represents the common ratio. However, the given series does not provide the first term "a." Without knowing the first term, it is not possible to calculate the sum of the series.

The given equation "x=y√−1" seems to be incomplete or contains a typographical error.

To calculate the area bounded above by the curve x=y√−1 and x=−59y^7 and below by the x-axis, we need to find the limits of integration and set up the definite integral.

First, we need to find the intersection points of the two curves. Equating y√−1 and −59y^7, we can solve for y to find the y-values at the intersection points. Then we can set up the integral as the definite integral from the lower limit to the upper limit of the curve y√−1. The limits of integration will be the y-values of the intersection points.

Once we have set up the integral, we can integrate the function y√−1 with respect to y and evaluate the result. This will give us the area bounded above by the curve x=y√−1 and x=−59y^7 and below by the x-axis.

Since L is zero, the Root Test tells us that the series ∑┬(k=1)┬(∞) ak converges.

To compute L = lim┬(k→∞)┬√(|ak|/k), we substitute the expression for ak into the limit:

L = lim┬(k→∞)┬√(|1/k^k|/k)

Simplifying the expression inside the square root:

L = lim┬(k→∞)┬√(1/k^(2k+1))

Since k^(2k+1) grows faster than k, we have:

To find the directional derivative of the function f(x, y) = √(xy) at point P(7, 7) in the direction from P to Q(10, 3), we need to calculate the dot product of the gradient of f at P with the unit vector in the direction from P to Q.

First, we find the gradient of f(x, y):

∇f(x, y) = (∂f/∂x, ∂f/∂y)

Taking partial derivatives:

∂f/∂x = (√(xy))' with respect to x = √(y)/2

∂f/∂y = (√(xy))' with respect to y = √(x)/2

Evaluating these partial derivatives at P(7, 7):

∂f/∂x at P(7, 7) = √(7)/2

∂f/∂y at P(7, 7) = √(7)/2

Next, we find the direction vector from P to Q:

Q - P = (10 - 7, 3 - 7) = (3, -4)

To obtain the unit vector in the direction from P to Q, we divide the direction vector by its magnitude:

||Q - P|| = √(3^2 + (-4)^2) = 5

Unit vector: (3/5, -4/5)

Finally, we calculate the directional derivative:

Duf(7, 7) = ∇f(7, 7) · (Q - P)

Duf(7, 7) = (√(7)/2, √(7)/2) · (3/5, -4/5)

Duf(7, 7) = (√(7)/2)(3/5) + (√(7)/2)(-4/5)

Duf(7, 7) = (3√(7)/10) - (4√(7)/10)

Duf(7, 7) = -√(7)/10

Therefore, the directional derivative of f(x, y) = √(xy) at P(7, 7) in the direction from P to Q(10, 3) is -√(7)/10.

The derivative of the function g(x) = 4x^2 - 2 using difference quotients is obtained by taking the limit as h approaches 0 of the expression [g(x + h) - g(x)] / h. The numerator of the difference quotient is 4(x + h)^2 - 2 - (4x^2 - 2), and after simplification, the derivative is equal to 8x.

To find the derivative of g(x) using difference quotients, we start with the expression [g(x + h) - g(x)] / h, where g(x) = 4x^2 - 2.

First, we substitute g(x + h) and g(x) into the difference quotient:

[g(x + h) - g(x)] / h = [4(x + h)^2 - 2 - (4x^2 - 2)] / h

Next, we simplify the numerator by expanding and simplifying:

= [4(x^2 + 2hx + h^2) - 2 - 4x^2 + 2] / h

= [4x^2 + 8hx + 4h^2 - 2 - 4x^2 + 2] / h

= (8hx + 4h^2) / h

= 8x + 4h

Finally, we take the limit as h approaches 0:

lim(h->0) (8x + 4h) = 8x
