the eigenvalues for the given boundary value problem are λ = 0 and λ = 1, and the corresponding eigenfunctions are y₁(x) = 1 and y₂(x) = \(x^{(1-\lambda)\).

To find the eigenvalues and eigenfunctions for the given boundary value problem, we can solve the differential equation and apply the boundary conditions.

First, let's rewrite the differential equation in standard form by dividing through by x²:

y'' + (1/x) y' + (λ/x²) y = 0

Now, let's assume the solution has the form y(x) = \(x^r\), where r is a constant to be determined. Substituting this into the differential equation:

\(x^r\) (r(r-1) + r + λ/x) = 0

Rearranging and simplifying:

r² + (λ - 1) r = 0

This is a quadratic equation for r. The solutions for r are:

r₁ = 0

r₂ = 1 - λ

These are the eigenvalues.

Next, we find the corresponding eigenfunctions for each eigenvalue by substituting the values of r back into the assumed form of the solution.

For r₁ = 0, the corresponding eigenfunction is y₁(x) = x⁰ = 1.

For r₂ = 1 - λ, the corresponding eigenfunction is y₂(x) = \(x^{(1-\lambda)\).

Therefore, the eigenvalues for the given boundary value problem are λ = 0 and λ = 1, and the corresponding eigenfunctions are y₁(x) = 1 and y₂(x) = \(x^{(1-\lambda)\).

The function g(x) is given by:

g(x) = (68/π) (1/x²) sin(π/4x²).

We have,

To find the integral of the function g(x) = ∫[0, x] (-34t cos(π/4t²)) dt, we can evaluate the integral using the fundamental theorem of calculus.

The antiderivative of -34t cos(π/4t²) with respect to t can be found by applying the chain rule in reverse.

We set u = π/4t² and find du/dt = -π/2t³.

Rearranging, we have dt = -(2/π) x (1/t³) du.

Substituting back into the integral:

g(x) = ∫[0, x] (-34tcos(π/4t²)) dt

= ∫[0, x] (-34tcos(u)) x -(2/π) x (1/t³) x du

= (68/π) x ∫[0, x] (cos(u)/t²) du.

Now, we can evaluate this integral.

The integral of (cos(u)/t²) with respect to u can be found using basic integration rules:

∫ (cos(u)/t²) du = (1/t²) x ∫ cos(u) du

= (1/t²) x sin(u) + C,

where C is the constant of integration.

Substituting back into the expression for g(x):

g(x) = (68/π)  [(1/t²) sin(u)] evaluated from 0 to x

= (68/π)  [(1/x²)  sin(π/4x²) - (1/0²)  sin(π/4 x 0²)]

= (68/π)  [(1/x²)  sin(π/4x²) - 0]

= (68/π) (1/x²) sin(π/4x²).

Therefore,

Step-by-step explanation:

Speed is the distance over time.  To find the average rate of speed for a trip, we simply need to take the total distance divided by the total time.

Avg. Speed = (188 miles + 197 miles) / (4 hours + 4.5 hours)

Avg. Speed = 45.29 miles per hour

Hence the average rate of speed for the trip was 45.29 miles per hour.

The x-coordinate of the point of inflection of the graph of g is: x = 2.5

To find the point of inflection of the graph of g, we need to find where the concavity of the graph changes.

Taking the derivative of g(x), we get:

g'(x) = d/dx ∫x^3(t^2 - 5t - 14)dt

Using the Fundamental Theorem of Calculus, we can evaluate this derivative as:

g'(x) = x^2 (x^2 - 5x - 14)

Now, to find where the concavity changes, we need to find where g''(x) = 0 or does not exist.

Taking the derivative of g'(x), we get:

g''(x) = d/dx (x^2 - 5x - 14) = 2x - 5

Setting g''(x) = 0, we get:

2x - 5 = 0

To determine the sum of money Jeff should invest on January 21, 2020, in order to reach $80000 on August 8, 2020, at an annual interest rate of 5%, we need to calculate the present value of the future amount using the time value of money concepts.

We can use the formula for the present value of a future amount to calculate the initial investment required. The formula is:

Present Value = Future Value / (1 + interest rate)^time

In this case, the future value is $80000, the interest rate is 5% per year, and the time period is from January 21, 2020, to August 8, 2020. The time period is approximately 6.5 months or 0.542 years.

Plugging these values into the formula, we have:

Present Value = $80000 / (1 + 0.05)^0.542

Evaluating the expression, we find that the present value is approximately $75609. Therefore, Jeff should invest approximately $75609 on January 21, 2020, to amount to $80000 on August 8, 2020, at a 5% annual interest rate.

Answer:

\(53 = 110 \left(\dfrac{1}{2}\right)^{\dfrac{x}{6}}\)

Step-by-step explanation:

The decay of a radioactive substance can be modeled using the half-life formula:

\(\large{\boxed{N(t)=N_0\left(\dfrac{1}{2}\right)^{\frac{t}{t_\frac{1}{2}}}}}\)

where:

In this case, the initial amount of substance is N₀ = 110 grams and the half-life is t_{1/2} = 6 days.

To find the number of days, x, required for the substance to decay to 53 grams, we can set N(t) = 53 and t = x.

Therefore, the equation that can be used to determine the number of days, x, required for the substance to decay to 53 grams is:

\(\boxed{53 = 110 \left(\dfrac{1}{2}\right)^{\dfrac{x}{6}}}\)

\(\hrulefill\)

To solve the equation, divide both sides by 110:

\(\left(\dfrac{1}{2}\right)^{\dfrac{x}{6}}=\dfrac{53}{110}\)

Take natural logarithms of both sides:

\(\ln \left(\dfrac{1}{2}\right)^{\dfrac{x}{6}}=\ln \dfrac{53}{110}\)

\(\textsf{Apply the power law:} \quad \ln x^n=n \ln x\)

\(\dfrac{x}{6}\ln \left(\dfrac{1}{2}\right)=\ln \left(\dfrac {53}{110}\right)\)

Multiply both sides by 6:

\(x\ln \left(\dfrac{1}{2}\right)=6\ln \left(\dfrac{53}{110}\right)\)

Divide both sides by ln(1/2):

\(x=\dfrac{6\ln \left(\dfrac{53}{110}\right)}{\ln \left(\dfrac{1}{2}\right)}\)

Evaluate:

\(x=6.32063555...\)

Therefore, the number of days required for the substance to decay to 53 grams is approximately 6.32 days, as calculated using the half-life formula.

The true statement of the parabola is (a) directrix will cross through the positive part of the y-axis.

Parabolas are examples of a conic section such that it is formed by the intersection of a cone with a plane parallel to its side.

From the question, the given parameters are:

Vertex = (0,0)

Focus = Negative side of the y-axis

A parabola has quite a number of forms, one of these forms is the general form.

The general form is represented as:

The vertex of the parabola is

(h, k) = (0, 0).

So, we have:

(x - 0)^2 = 4p(y - 0)

Evaluate the difference

x^2 = 4py

Since the focus is on the negative side, the value of p will be negative.

To determine if it would be unusual to randomly select 12 people and find that fewer than 5 recognize the Yummy brand name, we can use the concept of standard deviation and z-scores.

First, we need to calculate the z-score, which measures how many standard deviations an observation is from the mean. The formula for calculating the z-score is:

z = (x - μ) / σ

where

z = (5 - 9.3) / 0.99

z = -4.394

Next, we can consult a standard normal distribution table or use statistical software to find the corresponding percentile associated with the z-score. This percentile represents the probability of randomly selecting a group of 12 people with fewer than 5 recognizing the Yummy brand name.

In this case, the z-score of -4.394 corresponds to an extremely low percentile, close to 0.

The exact probability can be determined using the z-score and the standard normal distribution table.

Since the probability is extremely low, it would be considered unusual to randomly select 12 people and find that fewer than 5 recognize the Yummy brand name.

However, it's important to note that the definition of "unusual" may vary depending on the specific criteria or threshold chosen.

In statistical terms, a common threshold for defining unusual events is a significance level of 5% (or 0.05). If the probability of observing the event is lower than the significance level, it is considered unusual.

The exact value of cscθ is (35 * √(1190)) / 1190.

To find the value of cscθ (cosecant θ) given that cosθ = 1/√35 and sinθ < 0, we can use the reciprocal relationship between sine and cosecant.

Recall that cscθ is the reciprocal of sinθ. Since sinθ is negative, we can determine its value based on the quadrant in which θ lies.

In the unit circle, the cosine is positive in the first and fourth quadrants, while the sine is negative in the third and fourth quadrants.

Given that cosθ = 1/√35 and sinθ < 0, we can conclude that θ lies in the fourth quadrant.

Using the Pythagorean identity, sinθ = √(1 - cos^2θ), we can calculate the value of sinθ:

sinθ = √(1 - (1/√35)^2)

     = √(1 - 1/35)

     = √(34/35)

     = √34 / √35

     = (√34 / √35) * (√35 / √35)     [Multiplying numerator and denominator by √35 to rationalize the denominator]

     = √(34 * 35) / 35

     = √(1190) / 35

Now, since cscθ is the reciprocal of sinθ, we have:

cscθ = 1 / sinθ

     = 1 / (√(1190) / 35)

     = 35 / √(1190)

     = (35 * √(1190)) / 1190.

To calculate the per share basis, we divide the original purchase cost by the total number of shares (including the dividend shares).  In scenario b, Euclid receives a nontaxable preferred stock dividend of 20 shares. The preferred stock has a fair market value of $5,000, and the common stock, on which the preferred is distributed, has a fair market value of $75,000.

The tax consequences involve determining the new basis of the preferred stock and the common stock after the dividend. a. To find the per share basis of Euclid's common stock after receiving the stock dividend, we divide the original purchase cost by the total number of shares. The original purchase cost was $50,000 for 500 shares, which means the per share basis was $50,000/500 = $100. After receiving 20 additional shares as a dividend, the total number of shares becomes 500 + 20 = 520.

Therefore, the new per share basis is $50,000/520 = $96.15. b. In this scenario, Euclid receives a preferred stock dividend of 20 shares. The preferred stock has a fair market value of $5,000, and the common stock has a fair market value of $75,000. To determine the new basis of the preferred stock, we consider its fair market value.

Since the preferred stock dividend is nontaxable, its basis is equal to the fair market value, which is $5,000.
