The two cars will meet at a distance that is either 187 miles or 168 miles away from Boston.

To determine the distance from Boston where the two cars will meet, we need to consider their initial distances from Boston and the fact that they are moving towards each other at the same speed.

Let's denote the distance traveled by the car starting from point C as x miles. Since both cars are moving towards each other at the same speed, the distance traveled by the car starting from point D would be (256 - x) miles.

The total distance traveled by both cars should be equal to the sum of their initial distances. Therefore, we have the equation x + (256 - x) = 118. Simplifying this equation gives us 2x = 138, which means x = 69.

So, the car starting from point C would have traveled 69 miles, and the car starting from point D would have traveled (256 - 69) = 187 miles.

However, there is another possible scenario. If we assume that the car starting from point C travels (118 + 69) = 187 miles, then the car starting from point D would travel (256 - 187) = 69 miles.

If we have n identical books and k distinct shelves, with at most one book on each shelf, we can think of this as placing n balls into k distinct bins. Each ball (book) can only go into one bin (shelf). This is a classic combinatorial problem known as the "stars and bars" problem.

The solution can be expressed as (n + k - 1) choose (k - 1), or C(n+k-1,k-1), which is the number of ways to choose k-1 "dividers" to separate n "stars" (books) into k bins (shelves).

Intuitively, we can see that we need to place k-1 dividers among n stars, which is equivalent to choosing k-1 positions out of n+k-1 total positions to place the dividers. The remaining spaces will each contain one book, and we can do this in C(n+k-1,k-1) ways.

The given integral is evaluated using integration by substitution method. Let u = t2 – 4, then du/dt = 2t. Rewriting the integral in terms of u gives ∫(4/(2√2)) (u+4)^(3/2) du. Now applying the power rule of integration, we get (4/(5√2)) (u+4)^(5/2) + C. Substituting back u = t2 – 4, we get the final result as (4/(5√2)) (t2)^(5/2) – (4/(5√2)) (2^(5/2)) + C.

The given integral can be written as ∫(4/(2√2)) (t3/(t2 – 4)) dt. To evaluate this integral, we use integration by substitution method. Let u = t2 – 4, then du/dt = 2t. Solving for dt, we get dt = du/(2t). Substituting these values in the integral, we get ∫(4/(2√2)) ((t2 – 4 + 4)/(t2 – 4))^(3/2) (du/(2t)). Simplifying this, we get ∫(4/(2√2)) ((u+4)/(u))^(3/2) (du/(4√2)). Cancelling the 4s and 2s, we get ∫(u+4)^(3/2)/(u^(1/2)) du.
Now, using the power rule of integration, we get (4/(5√2)) (u+4)^(5/2) + C. Substituting back u = t2 – 4, we get the final result as (4/(5√2)) (t2)^(5/2) – (4/(5√2)) (2^(5/2)) + C.

The given integral is evaluated using integration by substitution method. The substitution u = t2 – 4 is used to simplify the integral. The final result is obtained by substituting the value of u back in the expression.

The constants α, β, and k are all zero, and the solution to the IVP is y(t) = e²{-2t}, with t = -0.5ln(7)  the condition limt→∞y(t) = 7,t = -0.5ln(7)

Using the method of undetermined coefficients to find the general solution of the differential equation:

y'' + 3y' + 2y = 0

The characteristic equation is:

r²2 + 3r + 2 = 0

Factoring this equation, we get:

(r + 2)(r + 1) = 0

So the roots are r1 = -2 and r2 = -1. Therefore, the general solution is:

y(t) = c1e^{-2t} + c2e^{-t}

Next, we use the information that y1(t) = e²{-3t} is a solution to the differential equation. Substituting this into the general solution, we get:

e²{-3t} = c1e²{-2t} + c2e²{-t}

equation to solve for c1 and c2. Multiplying both sides by e^{2t}, we get:

e²{-t} = c1 + c2e²t

Taking the limit as t approaches infinity,  that c1 must be zero in order for the right-hand side to converge to a finite value. Therefore, we have:

c1 = 0

Substituting this into the previous equation,

e²{-t} = c2e²t

Dividing both sides by e²t,

e²{-2t} = c2

Therefore, we have:

c2 = e²{-2t}

Substituting these values into the general solution,

y(t) = c1e²{-2t} + c2e²{-t} = e²{-2t}

So α = β = 0 and k = -2. Finally,  the information that limt→∞y(t) = 7. Since y(t) = e²{-2t}, we have:

limt→∞e²{-2t} = 7

Taking the natural logarithm of both sides,

-2t = ln(7)Solving for t,

t = -0.5ln(7)

The approximate standard deviation of returns of U.S. common stocks during the period between 1900 and 2017 is 20%.

Standard deviation is a measure of how much the returns of a particular asset, in this case U.S. common stocks, vary from the average return. It is a measure of the risk associated with investing in the asset.

According to data from the NYU Stern School of Business, the average annual return of U.S. common stocks between 1900 and 2017 was 11.44%, with a standard deviation of 20.00%. This means that the returns of U.S. common stocks during this period varied, on average, by 20% from the average return of 11.44%.

It is important to note that this is an approximate value, as the exact standard deviation may vary slightly depending on the data source and calculation method used.

The phenomenon of an unfair and/or unequal distribution of opportunities and resources among the people who make up a society is referred to as inequality. To different people and in various contexts, the word "inequality" may mean different things. Additionally, inequality has distinct yet overlapping social, economic, and geographic dimensions. The conflict between the normative concept of "deservingness" and the moral ethics of equity and social justice, on the one hand, and on the other, further complicates discussions about inequality. Inequalities that can be seen both within and between social groups have come to the forefront of public consciousness in recent years. The growing realization that inequality is systemic and ingrained in various socioeconomic and political structures is the result of this awareness. The contributions of geographers to the subject.
