In a right triangle with acute angles of 45°, the two legs are congruent. Let's denote the length of both legs as x.

Given that the length of leg PR is 2√6, we can set up the equation:

x = 2√6

To find the value of x, we square both sides of the equation:

x^2 = (2√6)^2

x^2 = 4 * 6

x^2 = 24

Taking the square root of both sides, we get:

x = √24

x = 2√6

So, the length of both legs PQ and QR is 2√6.

Therefore, the length of side QR is 2√6, and the length of side PQ is also 2√6.

The average value of f(x) over the interval [-10, 10] is 750.

The average value of the function f(x) = 3x^3 over the interval [-10, 10] can be found using the formula:

average value = (1/(b-a)) * ∫f(x) dx from a to b

Here, a = -10 and b = 10, so we have:

average value = (1/(10-(-10))) * ∫3x^3 dx from -10 to 10

= (1/20) * [(3/4)x^4] from -10 to 10

= (1/20) * [(3/4)(10^4 - (-10^4))]

= (1/20) * [(3/4)(10000 + 10000)]

The statement "IRI = |Nl" is false. because The symbol "|Nl" is not well-defined and it's not clear what it represents.

On the other hand, |N| represents the set of natural numbers, which are the positive integers (1, 2, 3, ...). These two sets are not equal.

Furthermore, the diagonalization argument is used to prove that the set of real numbers is uncountable, which means that there are more real numbers than natural numbers. This argument shows that it is impossible to construct a one-to-one correspondence between the natural numbers and the real numbers, even if we restrict ourselves to the interval [0, 1]. Hence, it is not possible to prove IRI = |N| using diagonalization argument.

It seems your question is about the diagonalization argument and cardinality of sets. A diagonalization argument is a method used to prove that certain infinite sets have different cardinalities. Cardinality refers to the size of a set, and when comparing infinite sets, we use the term "order."

In your question, you are referring to the sets N (natural numbers), IRI (real numbers), and the interval [0, 1]. The goal is to prove that the cardinality of the set of real numbers (|IRI|) is equal to the cardinality of the set of natural numbers (|N|).

Through a diagonalization argument, we can show that the cardinality of the set of real numbers in the interval [0, 1] (|IRI [0, 1]|) is larger than the cardinality of the set of natural numbers (|N|). This implies that the two sets cannot be put into a one-to-one correspondence.

Then, in order to prove that |IRI| = |N|, we would need to find a one-to-one correspondence between the two sets. However, the diagonalization argument shows that this is not possible.

Therefore, the statement in your question is False, because we cannot prove that |IRI| = |N| by showing a one-to-one correspondence between them.

Thus, the mean of X is µ and the variance of X is 2σ^2.

The moment-generating function of a random variable X is defined as mx(t) = E(e^tx), where E denotes the expected value.

In this case, the moment-generating function of X is given by mx(t) = e^(µt) / (1 - (σt)^2), for |t| < 1/σ.

To find the mean and variance of X, we need to differentiate the moment-generating function twice and evaluate it at t=0.

First, we differentiate mx(t) once with respect to t:

mx'(t) = µe^(µt) / (1 - (σt)^2)^2 + 2σ^2te^(µt) / (1 - (σt)^2)^2

Next, we differentiate mx(t) twice with respect to t:

mx''(t) = µ^2 e^(µt) / (1 - (σt)^2)^2 + 2σ^2 e^(µt) / (1 - (σt)^2)^2 + 4σ^4 t^2 e^(µt) / (1 - (σt)^2)^3 - 4σ^2 t e^(µt) / (1 - (σt)^2)^3

Evaluating these derivatives at t=0, we get:

mx'(0) = µ

mx''(0) = µ^2 + 2σ^2

Therefore, the mean of X is given by E(X) = mx'(0) = µ, and the variance of X is given by Var(X) = mx''(0) - (mx'(0))^2 = µ^2 + 2σ^2 - µ^2 = 2σ^2.

If f is a quasiconcave function, it means that for any two points in the domain of f, the set of points lying above the curve formed by f is a convex set. This implies that the set of maximizers of f is also convex.

To see why, suppose there are two maximizers of f, say x and y. Since f is quasiconcave, any point on the line segment connecting x and y lies above the curve formed by f.

Now, if there exists a point z on this line segment that is not a maximizer, we can construct a new point by moving slightly towards the maximizer. By the definition of quasiconcavity, this new point will also lie above the curve formed by f.

A function is quasiconcave if its upper level sets are convex. Let's assume that f is a quasiconcave function and let M be the set of maximizers of f. To show that M is convex, we need to show that if x and y are in M, then any point on the line segment between them is also in M.

A quasiconcave function f has the property that for any two points x, y in its domain, f(min(x, y)) ≥ min(f(x), f(y)). The set of maximizers contains all points in the domain where f achieves its maximum value.

To show that this set is convex, consider any two points x, y within the set of maximizers. Let z be any point on the line segment connecting x and y, such that z = tx + (1-t)y for t ∈ [0,1]. Since f is quasiconcave, f(z) ≥ min(f(x), f(y)). However, both f(x) and f(y) are maximum values, so f(z) must also be a maximum value.

Suppose x and y are in M, which means that f(x) = f(y) = c, where c is the maximum value of f. Since f is quasiconcave, its upper level set {z | f(z) ≥ c} is convex. Therefore, any point on the line segment between x and y is also in this set, which means that it maximizes f as well. Therefore, z is in the set of maximizers, proving the set is convex. Hence, M is convex.

To solve this initial value problem, we can use the method of integrating factors.

First, we identify the coefficients of the equation:

[tex](x^2 - 5) y' - 2xy = -2x(x^2 - 5)[/tex]

Next, we multiply both sides of the equation by the integrating factor, which is given by:

[tex]IF = e^{-∫(2x/(x^2-5)dx)} = e^{-2 ln|x^2-5|} = e^{ln(x^2-5)}^{(-2)} = (x^2-5)^{(-2)}[/tex]

Multiplying both sides of the equation by the integrating factor, we get:

[tex](x^2-5)^{-2} (x^2 - 5) y' - 2x(x^2-5)^{-2} y = -2x(x^2-5)^{-1}[/tex]

Simplifying the left-hand side using the product rule, we get:

[tex]d/dx [(x^2-5)^(-1)] y = -2x(x^2-5)^{-1}[/tex]

Integrating both sides with respect to x, we get:

[tex](x^2-5)^(-1) y = -ln|x^2-5| + C[/tex]

The series converges and its value is 8 - 1/b.

To evaluate the telescoping series ∑(infinity) 8^(1/n) - b^(1/(n + 1)), we need to use the property of telescoping series where most of the terms cancel out.

First, we can write the second term as b^(1/(n+1)) = (1/b)^(-1/(n+1)). Now, we can use the fact that a^(1/n) can be written as (a^(1/n) - a^(1/(n+1))) / (1 - 1/(n+1)) for any positive integer n. Using this property, we can rewrite the first term of the series as:

8^(1/n) = (8^(1/n) - 8^(1/(n+1))) / (1 - 1/(n+1))

Similarly, we can rewrite the second term of the series as:

(1/b)^(-1/(n+1)) = ((1/b)^(-1/(n+1)) - (1/b)^(-1/(n+2))) / (1 - 1/(n+2))

Now, we can combine the terms and get:

∑(infinity) 8^(1/n) - b^(1/(n + 1)) = (8^(1/1) - 8^(1/2)) / (1 - 1/2) + (8^(1/2) - 8^(1/3)) / (1 - 1/3) + (8^(1/3) - 8^(1/4)) / (1 - 1/4) + ... + ((1/b)^(-1/n)) / (1 - 1/(n+1))

As we can see, most of the terms cancel out, leaving us with:

To solve this equation, we can use separation of variables method. First, we can separate the variables by dividing both sides by (100-y), which gives us which involves isolating the variables on different sides of the equation and integrating both sides.

We are given the differential equation d y d t =

1 / (100-y)[tex]dydt[/tex] = 0.08 1/(100-y)dydt=0.08

Next, we can integrate both sides with respect to t and y, respectively. The left-hand side can be integrated using substitution, where u=100-y, du/dy=-1, and dt=du/(dy*dt), which gives us:

∫ 1 / [tex](100-y)dy[/tex] = − ∫ 1 / u d u = − ln ⁡ | u | = − ln ⁡ | 100 − y |

Similarly, the right-hand side can be integrated with respect to t, which gives us:

∫ 0 t 0.08 d t = 0.08 t + C

where C is the constant of integration. Combining the two integrals, we get:

− ln ⁡ | 100 − y | = 0.08 t + C

To find the value of C, we can use the initial condition [tex]y(0)=25,[/tex] which gives us:

− ln ⁡ | 100 − 25 | = 0.08 × 0 + C

C = − ln (75)

Thus, the solution to the differential equation is:

| 100 − y | = e − 0.08 t / 75

y = 100 − 75 e − 0.08 t

Let fX(x) and fY(y) be the PDFs of X and Y, respectively. Since X and Y are independent, the joint PDF is given by fXY(x,y) = fX(x) * fY(y), where * denotes the convolution operation.

To find the PDF of X+Y, we can use the change of variables technique. Let U = X+Y and V = Y. Then, we have X = U-V and Y = V. The Jacobian of the transformation is 1, so the joint PDF of U and V is given by fUV(u,v) = fX(u-v) * fY(v).

Using the convolution formula, we can find the PDF of U = X+Y as follows:

fU(u) = ∫ fUV(u,v) dv = ∫ fX(u-v) * fY(v) dv

= ∫ fX(u-v) dv * ∫ fY(v) dv

= e^(-u) * [1 - e^(-M u)]

where M is the parameter of the exponential distribution for Y.

Finally, using the convolution formula again, we can find the PDF of X – Y as:

fX-Y(z) = ∫ fU(u) * fY(u-z) du

= ∫ e^(-u) * [1 - e^(-M u)] * Me^(-M(u-z)) du

= M e^(-Mz) * [1 - (1+Mz) e^(-z)]

The PDF of X – Y can be found using the convolution formula. We first find the joint PDF of X+Y using the independence of X and Y, and then use the convolution formula to find the PDF of X – Y.

To find the maximum possible value of the error between the Maclaurin polynomial T3 of f(x) = e^x and the function value at x = 1.8, we need to use the Error Bound formula. The formula states that the absolute value of the error, |f(x) - Tn(x)|, is less than or equal to the maximum value of the nth derivative of f(x) times the absolute value of (x - a) raised to the power of n+1, divided by (n+1)!.

For the given function f(x) = e^x and Maclaurin polynomial T3, we have n = 3 and a = 0. The nth derivative of f(x) is also e^x. Substituting these values into the Error Bound formula, we get:

|f(x) - T3(x)| ≤ (e^c) * (x - 0)^4 / 4!

where 0 < c < x. Since we need to find the maximum possible value of the error for x = 1.8, we need to find the maximum value of e^c in the interval (0, 1.8). This maximum value occurs at c = 1.8, so we have:

|f(1.8) - T3(1.8)| ≤ (e^1.8) * (1.8)^4 / 4!

Rounding this to four decimal places, we get:

If(1.8) - T3(1.8) < 0.0105

The maximum possible value of the error between f(x) = e^x and its Maclaurin polynomial T3 at x = 1.8 is 0.0105. This means that T3(1.8) is a very good approximation of f(1.8), with an error of less than 0.011.

Therefore, we can find angle A by subtracting angles B and C from 180°:

A = 180° - B - C

A = 180° - 49.2° - 102°

A ≈ 28.8°

Now, we can use the Law of Sines to find the lengths of sides a and c. The Law of Sines states that the ratio of the length of a side to the sine of its opposite angle is the same for all sides of a triangle:

a/sin(A) = c/sin(C)

Plugging in the known values, we have:

52.8/sin(28.8°) = c/sin(102°)

Solving for c, we get:

c = (52.8 * sin(102°)) / sin(28.8°)

c ≈ 26

To find side a, we can use the Law of Sines again:

a/sin(A) = b/sin(B)

Plugging in the known values, we have:

a/sin(28.8°) = 40.9/sin(49.2°)

Step-by-step explanation:

Mathematical induction, the statement is true for all integers n > 1. For this, we will start with

Base Case: When n = 2, we have:

∑(5i – 4) = 5(1) – 4 + 5(2) – 4 = 2(5*2 - 3)/2 = 7

So, the statement is true for n = 2.

Inductive Hypothesis: Assume that the statement is true for some positive integer k, i.e.,

∑(5i – 4) = k(5k - 3)/2  for k > 1.

Inductive Step: We need to show that the statement is also true for k + 1, i.e.,

∑(5i – 4) = (k + 1)(5(k+1) - 3)/2

Consider the sum:

∑(5i – 4) from i = 1 to k + 1

This can be written as:

(5(1) – 4) + (5(2) – 4) + ... + (5k – 4) + (5(k+1) – 4)

= ∑(5i – 4) from i = 1 to k + 5(k+1) – 4

= [∑(5i – 4) from i = 1 to k] + (5(k+1) – 4)

= k(5k - 3)/2 + 5(k+1) – 4 by the inductive hypothesis

= 5k^2 - 3k + 10k + 10 – 8

= 5k^2 + 7k + 2

= (k+1)(5(k+1) - 3)/2

So, the statement is true for k + 1.

The 4th partial sum, s4, of the given series is 34.

To find the 4th partial sum, s4, of the series ∑(n - 2), where n starts from 9 and goes to infinity, we can compute the sum of the first four terms. Let's calculate s4 step by step:

s4 = (9 - 2) + (10 - 2) + (11 - 2) + (12 - 2)

= 7 + 8 + 9 + 10

= 34.

The 4th partial sum, s4, of the given series is 34. This means that if we add up the first four terms of the series, we obtain a sum of 34. However, since the series extends to infinity, the total sum cannot be determined exactly. The value of s4 represents only a finite approximation of the entire series.

The final expression would be: Φ((x-y - σ ϕ((t1/t)^(1/2))(exp[-(y-x)^2/(2σ^2(1-t1/t))] - exp[-(y+x)^2/(2σ^2(1-t1/t))]))/(σ(1 - ϕ((t1/t)^(1/2))(exp[-(y-x)^2/(2σ^2(1-t1/t))] + exp[-(y+x)^2/(2σ^2(1-t1/t))])))

First, let's start with some definitions. In this problem, we're working with a stochastic process B(t), which we assume to be a standard Brownian motion.

We want to compute the probability that the maximum value of B(s) over some interval [0,t] is less than or equal to a fixed value x, given that B(t1) = y.

In notation, we're looking for P{max B(s) <= x | B(t1) = y}.

To approach this problem, we're going to use the fact that the maximum value of a Brownian motion over an interval is distributed according to a Gumbel distribution.

Specifically, if we let M = max B(s) over [0,t], then the cumulative distribution function (CDF) of M is given by:

F_M(m) = exp[-exp(-(m - μ)/σ)]

where μ = E[M] = 0 and σ = Var[M] = t/3.

So, if we can compute the CDF of M conditioned on B(t1) = y, then we can easily compute the probability we're interested in.

To do this, we'll use a result from Brownian motion theory that says that the joint distribution of a Brownian motion at any finite collection of time points is multivariate normal. Specifically, if we let X = (B(t1), B(t2), ..., B(tn)) and assume that 0 <= t1 < t2 < ... < tn, then the joint distribution of X is:

X ~ N(0, Σ)

where Σ is an n x n matrix with entries σ^2 min(ti,tj).

In our case, we're interested in the joint distribution of B(t1) and M = max B(s) over [0,t]. Let's define Z = (B(t1), M). Using the result above, we can write the joint distribution of Z as:

Z ~ N(0, Σ')

where Σ' is a 2 x 2 matrix with entries:

σ^2 t1     σ^2 min(t1,t)
σ^2 min(t1,t)   σ^2 t/3

Now, we can use the conditional distribution of a multivariate normal to compute the CDF of M conditioned on B(t1) = y. Specifically, we have:

P(M <= m | B(t1) = y) = Φ((m-μ')/σ')

where Φ is the CDF of a standard normal distribution, and:

μ' = E[M | B(t1) = y] = y + σ ϕ((t1/t)^(1/2))(exp[-(y-x)^2/(2σ^2(1-t1/t))] - exp[-(y+x)^2/(2σ^2(1-t1/t))])
σ' = (Var[M | B(t1) = y])^(1/2) = σ(1 - ϕ((t1/t)^(1/2))(exp[-(y-x)^2/(2σ^2(1-t1/t))] + exp[-(y+x)^2/(2σ^2(1-t1/t))]))

where ϕ is the PDF of a standard normal distribution.

So, putting it all together, we have:

P{max B(s) <= x | B(t1) = y} = P(M <= x | B(t1) = y)
= Φ((x-μ')/σ')
= Φ((x-y - σ ϕ((t1/t)^(1/2))(exp[-(y-x)^2/(2σ^2(1-t1/t))] - exp[-(y+x)^2/(2σ^2(1-t1/t))]))/(σ(1 - ϕ((t1/t)^(1/2))(exp[-(y-x)^2/(2σ^2(1-t1/t))] + exp[-(y+x)^2/(2σ^2(1-t1/t))])))

Let's assume that the number of miles driven in a day is represented by "m".

The total rental cost for company A in terms of "m" can be expressed as:

Cost_A = 60 + 0.3m

The total rental cost for company B in terms of "m" can be expressed as:

Cost_B = 40 + 0.7m

We need to find the value of "m" for which the cost of renting from company A is less than the cost of renting from company B. In other words, we need to find the value of "m" that satisfies the inequality:

Cost_A < Cost_B

Substituting the expressions for Cost_A and Cost_B, we get:

60 + 0.3m < 40 + 0.7m

Simplifying this inequality, we get:

20 < 0.4m

Dividing both sides by 0.4, we get:

50 < m

Therefore, if the number of miles driven in a day is more than 50 miles, it would be more cost-effective to rent the truck from company A than from company B.

To find the largest possible value of p[a∪b]−p[a∩b], we need to first calculate both probabilities separately. The probability of a union b (p[a∪b]) can be found using the formula:
p[a∪b] = p[a] + p[b] - p[a∩b]

Substituting the values given in the problem, we get:
p[a∪b] = 0.7 + 0.9 - p[a∩b]
Now, we need to find the largest possible value of p[a∪b]−p[a∩b]. This can be done by minimizing the value of p[a∩b].
Since p[a∩b] is a probability, it must be between 0 and 1. Therefore, the smallest possible value of p[a∩b] is 0.
Substituting p[a∩b]=0, we get:
p[a∪b] = 0.7 + 0.9 - 0 = 1.6
Therefore, the largest possible value of p[a∪b]−p[a∩b] is:
1.6 - 0 = 1.6
In other words, the largest possible value of p[a∪b]−p[a∩b] is 1.6.
This means that if events a and b are not mutually exclusive (i.e., they can both occur at the same time), the probability of at least one of them occurring (p[a∪b]) is at most 1.6 times greater than the probability of both of them occurring (p[a∩b]).

The relation R = {(1, 1), (1, 2), (2, 1), (2, 2), (3, 3), (4, 4)} on {1, 2, 3, 4} is an equivalence relation because it satisfies the three properties of reflexivity, symmetry, and transitivity.

To find the equivalence class of [1], we need to identify all the elements that are related to 1 through the relation R. We can see from the definition of R that 1 is related to 1 and 2, so [1] = {1, 2}.

Similarly, to find the equivalence class of [4], we need to identify all the elements that are related to 4 through the relation R. Since 4 is related only to itself, we have [4] = {4}.

In summary, sets [1] = {1, 2} and [4] = {4}.
