Use the given information to determine the remaining five trigonometric values, Rationalize any denominators that contain radicals (Enter your answers in exact form.) CSC A 8/7, 90*

Answers

Answer 1

The required remaining five trigonometric values for A = 90 degrees, given CSC(A) = 8/7, are as follows:

SIN(A) = 7/8

COS(A) = 0

TAN(A) = Undefined

SEC(A) = Undefined

COT(A) = Undefined

Recall that CSC (cosecant) is the reciprocal of the sine function. We can use the Pythagorean identity to find the missing values.

Given:

CSC(A) = 8/7

A = 90 degrees

Using the Pythagorean identity:

CSC(A) = 1/SIN(A)

So, 1/SIN(A) = 8/7

To find SIN(A), we can take the reciprocal of both sides of the equation:

SIN(A) = 7/8

Now, we can use the SIN(A) value to find the remaining trigonometric values.

COS(A) can be found using the Pythagorean identity:

COS²(A) + SIN²(A) = 1

Substituting the SIN(A) value:

COS²(A) + (7/8)² = 1

COS²(A) = 15/64

COS(A) = √(15/64)

Since A is a right angle (90 degrees), COS(A) = 0.

The remaining trigonometric values can be calculated as follows:

TAN(A) = SIN(A) / COS(A)

TAN(A) = (7/8) / 0 = Undefined (since division by zero is not defined)

SEC(A) = 1 / COS(A)

SEC(A) = 1 / 0 = Undefined

COT(A) = 1 / TAN(A)

COT(A) = 1 / Undefined = Undefined

Therefore, the remaining five trigonometric values for A = 90 degrees, given CSC(A) = 8/7, are as follows:

SIN(A) = 7/8

COS(A) = 0

TAN(A) = Undefined

SEC(A) = Undefined

COT(A) = Undefined

Answers

The negation of "If the school is closed the fix is widespread" is (c) "If the flu is not widespread the school is not closed."

To construct the negation of the given statement, we need to negate both the antecedent and the consequent. The original statement "If the school is closed the fix is widespread" can be represented as "A -> B," where A represents the school being closed and B represents the fix being widespread.

To negate this statement, we need to negate both A and B and rearrange the sentence structure. Negating A gives us "not A" (the school is not closed), and negating B gives us "not B" (the fix is not widespread). Combining these negations, we get "not A -> not B," which can be written as "If the flu is not widespread the school is not closed."

In this negation, we are stating that if the flu is not widespread, then the school is not closed. This means that the presence of widespread flu is necessary for the school to be closed.

Suppose ū is an eigenvector of A corresponding to an eigenvalue = 2. Show that ū is an eigenvector of 51 - 3A+ A2. What is the corresponding eigenvalue?

Answers

It implies that ū is indeed an eigenvector of the matrix 51 - 3A + A2, since it satisfies the eigenvector equation, and the corresponding eigenvalue is λ = 43.

To solve this problem, we need to use the eigenvector equation:

Av = λv

where A is a matrix, v is an eigenvector, and λ is an eigenvalue.

In this problem, we know that ū is an eigenvector of A corresponding to an eigenvalue λ = 2. Therefore, we can use the above equation to see if ū is also an eigenvector of the matrix 51 - 3A + A2:

51 - 3A + A2v = λv

Since ū is an eigenvector of A, we can replace the A in the equation with 2:

51 - 3(2) + (2)2v = λv

Simplifying this equation, we get:

43v = λv

Therefore, this implies that ū is indeed an eigenvector of the matrix 51 - 3A + A2, since it satisfies the eigenvector equation, and the corresponding eigenvalue is λ = 43.

Express the given product as a sum or difference containing only sines or cosines.
cos(4x)cos(9x)

Answers

The expression of the given product as a sum or difference containing only sines or cosines is (cos(13x) + cos(5x))/2.

We know that, the formula to be used is: cos α cos β = [cos(α + β) + cos(α − β)]/2

Given cos(4x) cos(9x), we have to express the given product as a sum or difference containing only sines or cosines.

In order to apply the formula, we need to rewrite 2cos 4x cos 9x as cos (4x+9x)+cos(4x-9x)

Let us find the sum of the angles.4x + 9x = 13x4x - 9x = -5x

Substitute the values of sum and difference in the formula.

cos 4x cos 9x= (cos (4x+9x)+cos(4x-9x))/2

Therefore, cos(4x)cos(9x) = [cos(13x) + cos(-5x)]/2 = [cos(13x) + cos(5x)]/2

Hence, the expression of the given product as a sum or difference containing only sines or cosines is (cos(13x) + cos(5x))/2.

Cosine is a trigonometric function that relates the angle of a right triangle to the ratio of the length of the adjacent side to the hypotenuse. It is commonly denoted as cos and is defined as follows:

In a right triangle with an angle θ:

cos(θ) = adjacent side / hypotenuse

Alternatively, cosine can also be defined using the unit circle, where the cosine of an angle is the x-coordinate of the point on the unit circle that corresponds to that angle.

The squared error loss is the difference between the prediction made by the model and the actual value squared. Suppose during the construction of a decision tree we wish to specify a constant regional prediction function h" on the region Rw, based on the training data

In Ṛw, say

yi minimizes the squared-error loss. To minimize the squared error loss we must consider the least squares estimate of the mean response which is given by the following equation;

h"(x)= k-¹∑i=1k yi

This is simply the average response value for the data set.

Hence, we can say that,

3. An object moves along a straight line so that in t seconds its position is S = sin2t /3+cost^2t Find the object's velocity at time t = phi/4 (3 marks)

Answers

The object's velocity at time t = φ/4 is 0. This can be determined by taking the derivative of the position function S with respect to time t and evaluating it at t = φ/4. The derivative of S with respect to t is given by:

dS/dt = (2/3)sin(2t) + 2cos(t)sin(t)

Substituting t = φ/4, we have:

dS/dt = (2/3)sin(2(φ/4)) + 2cos(φ/4)sin(φ/4)

= (2/3)sin(φ/2) + 2cos(φ/4)sin(φ/4)

Since sin(φ/2) = 1 and sin(φ/4) = 1/√2, the equation simplifies to:

dS/dt = (2/3) + 2(1/√2)(1/√2)

= (2/3) + 2/2

= (2/3) + 1

= 5/3

Therefore, the velocity of the object at t = φ/4 is 5/3.

To find the velocity of the object at time t = φ/4, we need to calculate the derivative of the position function S with respect to time t and evaluate it at t = φ/4.

The position function is given by S = (sin^2(t))/3 + (cos(t))^2. To find the derivative of S with respect to t, we can use the rules of differentiation.

Applying the power rule, the derivative of (sin^2(t))/3 is (2/3)sin(t)cos(t), and the derivative of (cos(t))^2 is -2sin(t)cos(t).

Adding these derivatives together, we have: dS/dt = (2/3)sin(t)cos(t) - 2sin(t)cos(t).

Factoring out sin(t)cos(t), we get: dS/dt = (2/3 - 2)sin(t)cos(t).

Simplifying further, we have: dS/dt = (-4/3)sin(t)cos(t).

Now, substituting t = φ/4, we can determine the value of the derivative at that specific time.

Since sin(φ/4) = 1/√2 and cos(φ/4) = 1/√2, we have: dS/dt = (-4/3)(1/√2)(1/√2) = (-4/3)(1/2) = -2/3.

Therefore, the velocity of the object at t = φ/4 is -2/3, indicating that the object is moving in the negative direction along the straight line.

The P-value for the test of H0 : μ ≤ 46 versus H1 : μ > 46 is 0.024. A

The given MINITAB output presents the results of a hypothesis test for a population mean μ.

We are required to compute the P-value for the test of H0 : μ ≤ 46 versus H1 : μ > 46 using the output and an appropriate table.

The P-value for the given test is 0.024, which is less than the significance level of 0.05. Hence, we reject the null hypothesis and conclude that there is enough evidence to support the alternative hypothesis that the population mean is greater than 46.

To compute the P-value, we first need to determine the test statistic. The test statistic for the given hypothesis test is t = (X-bar - μ₀) / (s / √n), where X-bar is the sample mean, μ₀ is the hypothesized population mean, s is the sample standard deviation, and n is the sample size.

From the MINITAB output, we have the sample mean X-bar = 48.2, the sample standard deviation s = 4.9, and the sample size n = 25. The hypothesized population mean μ₀ = 46.

Substituting the given values in the formula for the test statistic, we get t = (48.2 - 46) / (4.9 / √25) = 2.04.

Using a t-distribution table with degrees of freedom (df) = n - 1 = 24 and the test statistic t = 2.04, we find the area to the right of the test statistic to be 0.024. This is the P-value for the given hypothesis test.

s this value is less than the significance level of 0.05, we reject the null hypothesis and conclude that there is enough evidence to support the alternative hypothesis that the population mean is greater than 46.

14. A national magazine claims that the average college student watches less television that general public. The national average is 30 hours per week, with a standard deviation of 1.5 hours. A sample of 40 college student has a mean of 26 hours. a = 0.05. Find H0 and H1. Is there enough evidence to reject the claim?

Answers

There is enough evidence to support the claim that the average college student watches less television than the general public.

How to explain the statistic

Sample mean = 26 hours

Population standard deviation (σ) = 1.5 hours

Sample size (n) = 40

Significance level (α) = 0.05

The formula for the one-sample t-test is:

t = (x - μ) / (σ / √n)

t = (26 - 30) / (1.5 / √40)

t = -4 / (1.5 / 6.3245553)

t ≈ -4 / 0.474342

t ≈ -8.439

Looking up the critical value from the t-distribution table or using statistical software, we find that the critical value at α = 0.05 with df = 39 is approximately -1.684.

Since the test statistic (-8.439) is much smaller (more negative) than the critical value (-1.684), we have strong evidence to reject the null hypothesis. Therefore, there is enough evidence to support the claim that the average college student watches less television than the general public.

(25 points) Find the solution of cʻy" + 5xy' + (4 – 4r)y=0, x > 0 of the form y = r" 922 n0 where co = 1. Enter T= Сп n=1,2,3,...

The solution of cay" + 5xy' + (4 – 3x)y=0, x > 0 of the form Y1 Gez", 10 where co = 1 is

T = {e^((-5x + √(25x² + 12x - 16))/2)z, e^((-5x - √(25x² + 12x - 16))/2)z}

n = 1, 2, 3, ...

To find the solution of the differential equation cay" + 5xy' + (4 – 3x)y = 0, where x > 0, of the form Y₁ = e^(λz), we can substitute Y₁ into the equation and solve for λ. Given that c = 1, we have:

1 * (e^(λz))'' + 5x * (e^(λz))' + (4 - 3x) * e^(λz) = 0

Differentiating Y₁, we have:

λ²e^(λz) + 5xλe^(λz) + (4 - 3x)e^(λz) = 0

Factoring out e^(λz), we get:

e^(λz) * (λ² + 5xλ + 4 - 3x) = 0

Since e^(λz) ≠ 0 (for any real value of λ and z), we must have:

λ² + 5xλ + 4 - 3x = 0

Now we can solve this quadratic equation for λ. The quadratic formula can be used:

λ = (-5x ± √(5x)² - 4(4 - 3x)) / 2

Simplifying further:

λ = (-5x ± √(25x² - 16 + 12x)) / 2

λ = (-5x ± √(25x² + 12x - 16)) / 2

Since we're looking for real solutions, the discriminant inside the square root (√(25x² + 12x - 16)) must be non-negative:

25x² + 12x - 16 ≥ 0

To find the solution for x > 0, we need to determine the range of x that satisfies this inequality.

Solving the inequality, we get:

(5x - 2)(5x + 8) ≥ 0

This gives two intervals:

Interval 1: x ≤ -8/5

Interval 2: x ≥ 2/5

However, since we are only interested in x > 0, the solution is x ≥ 2/5.

Therefore, the solution of the form Y₁ = e^(λz), where λ = (-5x ± √(25x² + 12x - 16)) / 2, is valid for x ≥ 2/5.

(a)[3] Completely describe the sampling distribution of the sample proportion of people who are in favour of increasing taxes to help balance the federal.

Answers

The sampling distribution of the sample proportion refers to the distribution of proportions obtained from multiple random samples taken from a population.

In this case, we are considering the proportion of people who are in favor of increasing taxes to help balance the federal budget.

The characteristics of the sampling distribution of the sample proportion depend on the population proportion, the sample size, and the sampling method. Here are some key points about the sampling distribution:

1. Central Limit Theorem: The sampling distribution of the sample proportion follows an approximate normal distribution, regardless of the shape of the population distribution, if the sample size is large enough. This is known as the Central Limit Theorem.

2. Mean and Standard Deviation: The mean of the sampling distribution of the sample proportion is equal to the population proportion. If the population proportion is denoted by p, then the mean of the sampling distribution is also p.

  The standard deviation (or standard error) of the sampling distribution can be calculated using the formula:

 

  Standard Deviation = sqrt[(p * (1 - p)) / n]

 

  where n is the sample size.

3. Shape and Symmetry: If the sample size is large enough, the sampling distribution can be approximated by a normal distribution. For smaller sample sizes, the shape may be slightly skewed, but it becomes more symmetric as the sample size increases.

4. Confidence Intervals: The sampling distribution is used to construct confidence intervals for the population proportion. The confidence interval provides a range of values within which we can be confident that the true population proportion lies.

5. Hypothesis Testing: The sampling distribution is also used for hypothesis testing involving the population proportion. It helps determine whether the observed sample proportion is significantly different from a hypothesized proportion.

Q1 Ratios 15 Points An Airbus A320 airplane has a length of 123 feet, a wingspan of 117 feet, and a height of 39 feet. Note that you should not convert units for any part of this problem. Q1.1 5 Points If a model of the plane is built to have a scale ratio of 1:40, determine the height. Round your answer to 2 decimal places and include units.

Answers

The height of the model plane is approximately 0.975 feet, or rounded to 2 decimal places, 0.98 feet. To determine the height of the model plane, we can use the scale ratio of 1:40.

Let's denote the height of the model plane as h_model.

Given:

Actual height of the Airbus A320 plane = 39 feet

Scale ratio = 1:40

The scale ratio indicates that every 1 unit in the model represents 40 units in the actual object.

So, we can set up the following proportion:

h_model / 1 = 39 / 40

To find h_model, we can cross-multiply and solve for it:

h_model = (39 * 1) / 40

= 39 / 40

≈ 0.975

Therefore, the height of the model plane is approximately 0.975 feet, or rounded to 2 decimal places, 0.98 feet.

Answers

We need to use the inverse function of the given CDF, i.e., we need to solve for x in the equation F(x) = U, where U is a random number generated from a Uniform(0,1) distribution.

The inverse transformation method is a technique used to generate random numbers from any probability distribution, provided we know its CDF and can invert it to obtain the inverse CDF. It is a simple and elegant method that exploits the fact that a Uniform(0,1) random variable has a known CDF, i.e., F(u) = u for 0 ≤ u ≤ 1, and its inverse function is simply F⁻¹(x) = x for 0 ≤ x ≤ 1. Thus, if we can transform a Uniform(0,1) random variable to any other distribution by inverting its CDF, we can generate random numbers from that distribution by applying the inverse transformation method.

Answers

a) The probability distribution is Lf(X₁, X₂, X₃,........Xₙ, μ, σ²)= [tex](\frac{1}{2\pi \sigma^2} )^\frac{n}{2} e^-\frac{1}{2\sigma^2} \sum (X_i-\mu)^2[/tex]

b) The Maximum Likelihood Estimator of σ is [tex]\sqrt{\frac{n}{2}\sum(X_i-\mu })^2[/tex].

MLE (Maximum Likelihood Estimator) is a heavily discussed topic in inferential statistics. An analyst attempting to find the suitable parameters for every given probability distribution would use the MLE. It is possible to do this by using the log and differentiation on the specified function.

Let X₁, X₂, X₃,........Xₙ be the random sample taken from the Normal distribution with mean mu(known) and variance σ²(unknown)

a) The probability distribution would be:

f(Xi, μ, σ²) = 1/√2πσ² [tex]e^-\frac{1}{2\sigma^2} (X_i-\mu)^2[/tex]

Lf(X₁, X₂, X₃,........Xₙ, μ, σ²)=f(Xi, μ, σ²)

Lf(X₁, X₂, X₃,........Xₙ, μ, σ²)= [tex](\frac{1}{2\pi \sigma^2} )^\frac{n}{2} e^-\frac{1}{2\sigma^2} \sum (X_i-\mu)^2[/tex] --------(1)

Log likelihood function:

By taking natural log on both sides of equation (1),

Lf(X₁, X₂, X₃,........Xₙ, μ, σ²)= [tex]-\frac{n}{2}ln(2\pi )- \frac{n}{2}ln(\sigma^2)-\frac{1}{2\sigma^2} \sum(X_i-\mu)^2\timesln(e)[/tex] --------(2)

So, the probability distribution is f(Xi, μ, σ²) = 1/√2πσ² [tex]e^-\frac{1}{2\sigma^2} (X_i-\mu)^2[/tex]

b) MLE (Maximum Likelihood Estimator):

Taking the differentiation with respect to σ², assuming μ is known (constant); and equating it to the zero in order to get the maxima of the function:

Thus, the MLE of σ is [tex]\sqrt{\frac{n}{2}\sum(X_i-\mu })^2[/tex]

Therefore,

a) The probability distribution is Lf(X₁, X₂, X₃,........Xₙ, μ, σ²)= [tex](\frac{1}{2\pi \sigma^2} )^\frac{n}{2} e^-\frac{1}{2\sigma^2} \sum (X_i-\mu)^2[/tex]

Use Newton's Method to approximate the solution to the cquation - 7 = 0. In particular, using X2 = 2, calculate Xz and X3 (Recall: Xn+1 = xn relation] . Round to three decimal places.

Answers

A different initial guess that does not make the denominator zero. The given equation has only one root, which is x = -7.

Newton's method is an iterative formula that approximates the roots of a function.

In this case, we want to approximate the root of the equation -7 = 0 using Newton's method.

The iterative formula for Newton's method is given by the following:

Xn+1 = xn - f(xn)/f'(xn)where

f(x) = -7 and f'(x) = 0

(derivative of a constant is zero)Let X2 = 2, so our initial guess is x2 = 2.

Using this value of X2,

we can find the next approximation, X3:X2 = 2X3 = X2 - f(X2)/f'(X2)X3 = 2 - (-7)/(0) (substituting values)X3 = undefined (division by zero)The derivative of f(x) = -7 is f'(x) = 0,

which means that the denominator in the iterative formula becomes zero.

This indicates that the Newton's method has failed to approximate the root of the equation. We need to try a different initial guess that does not make the denominator zero. The given equation has only one root, which is x = -7.

Answers

The minimum value of z = 2x + 4y for the given set of constraints is -∞ (negative infinity), and there is no maximum value. To find the minimum and maximum values of z = 2x + 4y, we need to consider the given set of constraints:

2x + y ≤ 20, 10x + y ≥ 36, and 2x + 5y ≥ 36. These inequalities define the feasible region in which the values of x and y must satisfy all the constraints simultaneously.

To determine the minimum value, we look for the point within the feasible region that gives the lowest value of z. However, in this case, the feasible region formed by the given constraints is unbounded, meaning there is no specific limit or boundary. Therefore, we cannot find a minimum value for z, and it is -∞ (negative infinity).

As for the maximum value, since the feasible region is unbounded, the line representing the objective function z = 2x + 4y can extend indefinitely without any upper limit. Consequently, there is no maximum value for z within this set of constraints. In conclusion, the minimum value of z = 2x + 4y for the given set of constraints is -∞ (negative infinity), and there is no maximum value.

The value of the integral is 135.

To find the value of the given integral, we can use the linearity property of integrals. We have:

∫[-90,-26] (6f(x) + 4g(x) - h(x)) dx = 6∫[-90,-26] f(x) dx + 4∫[-90,-26] g(x) dx - ∫[-90,-26] h(x) dx

Substituting the given values:

∫[-90,-26] (6f(x) + 4g(x) - h(x)) dx = 6(14) + 4(20) - 29

Calculating the expression:

∫[-90,-26] (6f(x) + 4g(x) - h(x)) dx = 84 + 80 - 29

∫[-90,-26] (6f(x) + 4g(x) - h(x)) dx = 135

b. The formula expressing the temperature T as a function of the number of chirps per minute (R) for the snowy cricket would be T(R) = 4R + 40

a) To express the statement as a formula giving the temperature T as a function of the number of chirps per 15 seconds for the snowy tree cricket (TE), we can use the given information that the temperature can be estimated by counting the number of chirps in 15 seconds and adding 40. Let's denote the number of chirps per 15 seconds as C.

The formula for estimating the temperature T in Fahrenheit would be:

T = C + 40

Therefore, the formula expressing the temperature T as a function of the number of chirps per 15 seconds for the snowy tree cricket is:

T(C) = C + 40

b) To transform the expression from chirps per 15 seconds (C) into an equivalent one giving the temperature T as a function of the number of chirps per minute (R) for the snowy cricket, we need to convert the units.

We know that there are 60 seconds in a minute. So, the number of chirps per minute (R) can be calculated by multiplying the number of chirps per 15 seconds (C) by 4 (since 15 seconds is 1/4 of a minute).

5 G USE IMPLICIT DIFFERENTIATION 2x3+3 y4 - 6xy=58 (-1,2) TYE VOLUME OF À CYLINDER IS V=71R2X WYERE R=RADIUS AND H= VEIGIT IF THE RADIUS IS 3 TIMES ZHE LEGAT Ano THE VOLUME INCREASES AT 10 anys HOW FAST DOES THE RADIUS DREASE How WHEN THE RADIUS 6 cm

Answers

The radius decreases at a rate of approximately 0.0117 cm/year when the radius is 6 cm and the volume increases at 10 cubic units per year.

To solve the equation 2x^3 + 3y^4 - 6xy = 58 using implicit differentiation, we differentiate both sides of the equation with respect to x. Let's go step by step:

Differentiating 2x^3 + 3y^4 - 6xy = 58 with respect to x:

6x^2 + 12x(dy/dx) + 12y^3(dy/dx) - 6y - 6x(dy/dx) = 0

Combining like terms:

6x^2 - 6y + 6x(dy/dx) + 12x(dy/dx) + 12y^3(dy/dx) = 0

Rearranging the equation:

(6x^2 + 12x + 12y^3) (dy/dx) = 6y - 6x

Dividing both sides by (6x^2 + 12x + 12y^3):

(dy/dx) = (6y - 6x) / (6x^2 + 12x + 12y^3)

Now, let's find the rate at which the radius decreases when the volume increases at 10 cubic units per year. We have the volume formula V = 71R^2, where R is the radius and V is the volume.

We are given that the radius is 3 times the legat (let's assume you meant "legth"). So, let's say the length is L, then the radius would be 3L.

Differentiating V = 71R^2 with respect to time (t):

dV/dt = d/dt (71R^2)

dV/dt = 2(71R)(dR/dt)

dV/dt = 142R(dR/dt)

Since we know that dV/dt = 10 cubic units per year, we can substitute that into the equation:

10 = 142R(dR/dt)

Now, we are given that the radius is 6 cm. Plugging that into the equation:

10 = 142(6)(dR/dt)

Simplifying:

10 = 852(dR/dt)

Finally, solving for dR/dt:

dR/dt = 10 / 852

dR/dt ≈ 0.0117 cm/year

Therefore, the radius decreases at a rate of approximately 0.0117 cm/year when the radius is 6 cm and the volume increases at 10 cubic units per year.

What is a quadratic equation of motion?

A quadratic equation is an equation in which the highest power of the unknown is 2.

Since the height in feet of a thrown football is modeled by the equation f(t) = 6 + 30t − 16t², where time t is measured in seconds. To select the statements that best describe the squared term −16t², we proceed as follows.

Comparing the equation f(t) = 6 + 30t − 16t² with s = h + ut - 1/2at² where

h = initial height u = initial speed of object andg = acceleration due to gravity andt = time

We see that

the -16t² corresponds to the gravitational acceleration term of the object.Also, the -16t² is subtracted from the 6 + 30t term until the football reaches its the ground.

So, the statements that best describe the squared term −16t² are

To find the extreme values of the function F(x, y) = xy subject to the constraint[tex]4x^2 + y^2 = 8[/tex] using Lagrange multipliers, we need to set up the following equations:

∇F = λ∇g (where ∇ denotes the gradient)

[tex]4x^2 + y^2 = 8[/tex] Here, λ is the Lagrange multiplier. First, let's find the gradient of F and g: ∇F = (∂F/∂x, ∂F/∂y) = (y, x) ∇g = (∂g/∂x, ∂g/∂y) = (8x, 2y)

Setting up the equations: y = λ(8x) x = λ(2y)

[tex]4x^2 + y^2 = 8[/tex] From the first two equations, we can rewrite them as:

y = 8λx x = 2λy Now, we substitute these equations into the third equation:

[tex]4(2λy)^2 + (8λx)^2 = 816λ^2y^2 + 64λ^2x^2 = 816λ^2(y^2 + 4x^2) = 8λ^2(y^2 + 4x^2) = 1/2[/tex]Since the left-hand side of the equation is a constant, the right-hand side should also be a constant. Let's denote this constant as k:

[tex]y^2 + 4x^2 = k[/tex] Now, we have a system of equations: y = 8λx x = 2λy [tex]y^2 + 4x^2 = k[/tex] Substituting equation 1 into equation 2, we get: x = 2λ(8λx) x = 16[tex]λ^2x[/tex] Simplifying: 1 = 16[tex]λ^2[/tex] λ = ±1/4

Now, we can substitute the values of λ into equations 1 and 2 to find the corresponding values of x and y: If λ = 1/4: y = 2x x = y/4 Therefore, the extreme values of the function F(x, y) = xy subject to the constraint [tex]4x^2[/tex] + [tex]y^2[/tex] = 8 occur at points (x, y) = (y/4, y) and (x, y) = (-y/4, y), where k = [tex]5y^2/4.[/tex]

To determine the extreme values, we substitute the expressions for x and y into the function F(x, y) = xy: If λ = 1/4: F(x, y) = (y/4)y =[tex]y^2/4[/tex] If λ = -1/4: F(x, y) = (-y/4)y = [tex]-y^2/4[/tex]

Answers

(a) The expected number of junk emails that an individual receives in an 8-hour day is 12.

(b) The probability that an individual receives more than two junk emails for the next three hours is approximately 0.08.

(c) The probability that an individual receives no junk email for two hours is approximately 0.05.

(a) The expected number of junk emails can be calculated by multiplying the mean rate (λ) by the number of hours:

Expected number = λ * time

In this case, the mean rate λ is 1.5 emails per hour, and the time is 8 hours.

Expected number = 1.5 * 8 = 12

Therefore, the expected number of junk emails an individual receives in an 8-hour day is 12.

(b) To calculate the probability of receiving more than two junk emails for the next three hours, we can use the cumulative distribution function (CDF) of the Poisson distribution. The CDF gives the probability of observing up to a certain number of events.

Using the Poisson distribution with a mean of 1.5, we can calculate:

P(X > 2) = 1 - P(X ≤ 2)

Calculating this, the probability is approximately 0.08.

(c) The probability of receiving no junk email for two hours can be calculated using the Poisson distribution with a mean of 1.5. Since the mean is the average rate per hour, we need to adjust the time to match the rate.

Using the Poisson distribution with a mean of 1.5 and a time of 2 hours, we can calculate:

P(X = 0)

Calculating this, the probability is approximately 0.05.

The solution of the given differential equation is y =  x⁴ ∑ (-1)ⁿ [(n+3)(n+4)(n+5)...(2n+3)]/[(n!)(3)(2)(1)] and the value of r is 4 and the value of cₙ is (-1)ⁿ [(n+3)(n+4)(n+5)...(2n+3)]/[(n!)(3)(2)(1)].

Given: x²y′′ + 5xy′ + (4+6x)y = 0, x > 0.

To find: The solution of the given differential equation in the form y₁ = x^r ∑ cₙ xⁿ n=0, where c₀=1.

Solution: Let's assume the solution of the given differential equation is of the form y₁=x^r ∑ cₙ xⁿ n=0---(1).

Differentiating (1) w.r.t x, we get y′=rx^(r-1) ∑ cₙ xⁿ + x^r ∑ ncₙ x^(n-1)---(2).

Differentiating (2) w.r.t x, we get

y′′=r(r-1)x^(r-2) ∑ cₙ xⁿ + 2rx^(r-1) ∑ ncₙ x^(n-1) + x^r ∑ n(n-1)cₙ x^(n-2)---(3).

Now substitute (1), (2) and (3) in the given differential equation, we get,

x²[r(r-1)x^(r-2) ∑ cₙ xⁿ + 2rx^(r-1) ∑ ncₙ x^(n-1) + x^r ∑ n(n-1)cₙ x^(n-2)] + 5x[rx^(r-1) ∑ cₙ xⁿ + x^r ∑ ncₙ x^(n-1)] + (4+6x)x^r ∑ cₙ xⁿ = 0

On simplification, we get,

∑ [(r(r-1)cₙ + 5rcₙ + (4+6(n+1))cₙ) x^(r+n)] = 0

Hence, we get the following recurrence relation:

r(r-1)cₙ + 5rcₙ + (4+6(n+1))cₙ = 0

⇒ r(r+4)cₙ = -(6n+4)cₙ

⇒ cₙ₊₁/cₙ = - (r+n+3)(r+n+2)/(r+4)

On solving the recurrence relation, we get

cₙ = (-1)ⁿ [r(r+1)(r+2)(r+3)...(r+n-1)]/[(n!)(4)(3)(2)(1)]

Since c₀=1

⇒ c₀ = (-1)⁰ [r(r+1)(r+2)(r+3)...(r+0-1)]/[(0!)(4)(3)(2)(1)]

⇒ 1 = r/4

⇒ r = 4

Hence, the solution of the given differential equation is

y = y₁

= x⁴ ∑ cₙ x^ⁿ

= x⁴ ∑ (-1)ⁿ [(4)(5)(6)...(4+n-1)]/[(n!)(4)(3)(2)(1)]

y = x⁴ ∑ (-1)ⁿ [(n+3)(n+4)(n+5)...(2n+3)]/[(n!)(3)(2)(1)]

Therefore, the value of r is 4 and the value of cₙ is (-1)ⁿ [(n+3)(n+4)(n+5)...(2n+3)]/[(n!)(3)(2)(1)].
