Consider the sequence defined by xo = 1,21 = 3 and n = 2xn-1 Xn-2 for any n ≥ 2. Prove that In = 2n + 1 for all n ≥ 0. (Hint: You need to use strong induction, and you need to check both n = 0 and n = 1 for the base case.)

To determine whether the linear transformation T: R³ -> R³ is diagonalizable, we need to check if there exists a basis for R³ consisting of eigenvectors of T.

Given three vectors (1, 1, 1), (0, 1, 1), and (1, 2, 3) along with their respective image vectors (2, 2, 2), (0, -3, -3), and (-1, -2, -3), we can check if these vectors satisfy the condition for eigenvectors.

Let's start by computing the eigenvectors and eigenvalues.

For the first vector, (1, 1, 1):

T(1, 1, 1) = (2, 2, 2)

To find the eigenvalues λ, we solve the equation T(v) = λv, where v is the eigenvector:

(2, 2, 2) = λ(1, 1, 1)

Simplifying the equation, we get:

2 = λ

2 = λ

2 = λ

From this equation, we see that λ = 2.

Now, let's check if the other vectors also have the same eigenvalue.

For the second vector, (0, 1, 1):

[tex]T(0, 1, 1) = (0, -3, -3)[/tex]

(0, -3, -3) ≠ λ(0, 1, 1) for any value of λ.

Therefore, (0, 1, 1) is not an eigenvector of T.

Similarly, for the third vector, (1, 2, 3):

T(1, 2, 3) = (-1, -2, -3)

(-1, -2, -3) ≠ λ(1, 2, 3) for any value of λ.

Therefore, (1, 2, 3) is not an eigenvector of T.

Since we have only found one eigenvector (1, 1, 1) with the corresponding eigenvalue of λ = 2, we do not have a basis of three linearly independent eigenvectors. Therefore, T is not diagonalizable.

The correct answer is:

The linear transformation T: R³ -> R³ is not diagonalizable.

Let's find the length of the hypotenuse (r) using the Pythagorean theorem

r = √((-7)² + (-4)²)

Next, we can determine the values of the trigonometric functions:

sin(θ) = opposite/hypotenuse = -4/√(65)

cos(θ) = adjacent/hypotenuse = -7/√(65)

tan(θ) = sin(θ)/cos(θ) = (-4/√(65)) / (-7/√(65)) = 4/7

csc(θ) = 1/sin(θ) = √(65)/(-4)

To calculate the p-value, we can use the formula for the test statistic of a sample standard deviation:

t = (s - σ) / (s/√n)

where t is the test statistic, s is the sample standard deviation, σ is the hypothesized population standard deviation, and n is the sample size.

In this case, we have s = 2.392, σ = 3.9, and n = 24.

Substituting these values into the formula, we get:

t = (2.392 - 3.9) / (2.392/√24)

Now, we can use the t-distribution table or a calculator to find the corresponding p-value for the calculated test statistic. Let's assume the p-value is P.

The given statement is false because the value of s does not equal 5-16-80 centimeters when r is 5 centimeters and 0 is 16 degrees.

In the statement, r is given as 5 centimeters, which represents the radius of a circle. However, the value of 0 is provided in degrees, which is a unit of measurement for angles. In order to calculate the length of an arc, which is represented by s, both the radius and the angle must be measured in the same unit, typically radians.

Therefore, since the statement mixes the units of measurement (centimeters for r and degrees for 0), the statement is false. The correct representation would require converting the angle from degrees to radians, and then using the appropriate formula to calculate the arc length.

The Laplace transformation technique was applied to the initial value problem, but it was determined that the problem has no solution due to the contradiction in the initial conditions.

Applying the Laplace transform to the given differential equation, we get 3s²Y(s) - 4Y(s) = 1/(s-3)³. Next, we use partial fraction decomposition to express the right-hand side as a sum of simpler fractions. By solving the resulting equation for Y(s), we find Y(s) = 1/(3s²(s-3)³). Now, we need to find the inverse Laplace transform of Y(s) to obtain the solution y(t). We can use tables or known Laplace transforms to simplify the expression. After applying the inverse Laplace transform, we obtain the solution y(t) = (t²/2)(1 - e³t).

To satisfy the initial conditions, we substitute y(0) = 0 and y'(0) = 0 into the solution. By evaluating these conditions, we find that 0 = 0 and 0 = -3/2. However, the second condition contradicts the first. Therefore, the given initial value problem does not have a solution.

The solution to the equation is approximately $94.65.

To solve the equation x(1.15)3 + $140 + x/1.152 = $420/1.152, we can follow these steps. First, we need to simplify the equation by applying the exponent and division operations.

1.15 raised to the power of 3 is 1.487875, so the equation becomes:

x * 1.487875 + $140 + x/1.152 = $420/1.152.

Next, let's eliminate the fraction by multiplying both sides of the equation by 1.152:

1.152 * x * 1.487875 + 1.152 * $140 + x = $420.

Simplifying further, we have:

1.73556x + $161.28 + x = $420.

Combining like terms, we get:

2.73556x + $161.28 = $420.

Now, let's isolate the variable x by subtracting $161.28 from both sides:

2.73556x = $420 - $161.28.

Simplifying the right side, we have:

2.73556x = $258.72.

Finally, divide both sides by 2.73556 to solve for x:

x = $258.72 / 2.73556.

Calculating this expression, we find that x ≈ $94.65 (rounded to the nearest cent).

Therefore, the solution to the equation is x ≈ $94.65.

the current I is approximately 8.14A, and the current I₂ is approximately 4.03A.

To determine the currents in the circuit, we need to apply Kirchhoff's laws and solve the resulting system of equations.

Let's label the currents in the circuit as follows:

- The current through the 1Ω resistor on the left branch is I.

- The current through the 3Ω resistor on the right branch is I₂.

Using Kirchhoff's voltage law (KVL) for the loop on the left side of the circuit, we can write:

12V - 1Ω * I - 1Ω * (I - I₂) = 0

Simplifying the equation, we have:

12V - I - I + I₂ = 0

-2I + I₂ = -12V   (Equation 1)

Using Kirchhoff's voltage law (KVL) for the loop on the right side of the circuit, we can write:

9V - 3Ω * I₂ - 1Ω * (I₂ - I) = 0

Simplifying the equation, we have:

9V - 3I₂ - I₂ + I = 0

I - 4I₂ = -9V   (Equation 2)

We now have a system of two equations with two variables (I and I₂). We can solve this system of equations to find the values of I and I₂.

To solve the system, we can use substitution or elimination. Let's use the elimination method.

Multiplying Equation 1 by 4, we get:

-8I + 4I₂ = -48V   (Equation 3)

Adding Equation 3 to Equation 2, we eliminate I and solve for I₂:

I - 4I₂ + (-8I + 4I₂) = -9V - 48V

-7I = -57V

I = 8.14A

Substituting the value of I back into Equation 2, we can solve for I₂:

8.14A - 4I₂ = -9V

-4I₂ = -9V - 8.14A

I₂ = 4.03A

In hypothesis testing, the Type I error is defined as the probability of rejecting the null hypothesis when it is actually true, while the Type II error is defined as the probability of not rejecting the null hypothesis when it is actually false.

The hypothesis testing is a statistical technique that helps in testing the hypothesis made about the population based on a sample.

Hypothesis testing involves the following steps.1. Null Hypothesis (H0): The null hypothesis is the statement that is being tested in the hypothesis testing.

The null hypothesis states that there is no significant difference between the sample and the population. It is denoted by H0.2.

Alternate Hypothesis (H1): The alternative hypothesis is the statement that contradicts the null hypothesis. It is denoted by H1.3.

Level of Significance (α): The level of significance is the probability of rejecting the null hypothesis when it is true. It is usually set to 0.05 or 0.01.4.

Test Statistic: The test statistic is a value calculated from the sample data that helps in testing the null hypothesis.5. Critical Region: The critical region is the region in which the null hypothesis is rejected.

It is defined by the level of significance and the test statistic.6. P-value: The p-value is the probability of obtaining a test statistic as extreme as the one observed, assuming that the null hypothesis is true.

If the p-value is less than the level of significance, then the null hypothesis is rejected.

Otherwise, it is accepted.Type I error: A Type I error occurs when the null hypothesis is rejected when it is actually true.

The probability of making a Type I error is equal to the level of significance (α).Type II error: A Type II error occurs when the null hypothesis is not rejected when it is actually false. The probability of making a Type II error is denoted by β. The power of the test is (1 - β).

W_LS = (8.1 + 8.05 + 8.15) / 3

This is the least squares estimate of W.

logL(W) = ∑ log(f(y_i - W)),

Since the logarithm is a strictly increasing function, maximizing the log-likelihood function gives the same result as maximizing the likelihood function.

Under the normal distribution, we know that the maximum likelihood estimate of the mean is simply the sample mean, which is the same as the least squares estimate in this case. Thus,

To determine the values of p for which the improper integral ∫(0 to 1) 1/x^p dx converges, we can use the substitution u = 1/x.

First, let's perform the substitution. We have u = 1/x, so we can rewrite the integral as follows:

∫(0 to 1) 1/x^p dx = ∫(u(1)=∞ to u(0)=1) u^p du.

Note that the limits of integration have been reversed since the substitution u = 1/x changes the direction of integration.

Now, let's evaluate this integral with the reversed limits of integration:

∫(u(1)=∞ to u(0)=1) u^p du = lim(b→0) ∫(1 to b) u^p du.

Next, we can evaluate the integral:

∫(1 to b) u^p du = [u^(p+1) / (p+1)] evaluated from 1 to b

                 = (b^(p+1) / (p+1)) - (1^(p+1) / (p+1))

                 = (b^(p+1) - 1) / (p+1).

Now, we can take the limit as b approaches 0:

lim(b→0) (b^(p+1) - 1) / (p+1).

To determine the convergence of the integral, we need to analyze the limit above.

If the limit exists and is finite, the integral converges. Otherwise, it diverges.

For the limit to exist and be finite, the numerator (b^(p+1) - 1) should approach a finite value as b approaches 0. This happens when p+1 > 0.

So, we need p+1 > 0, which gives us p > -1.

Therefore, the improper integral ∫(0 to 1) 1/x^p dx converges for p > -1.

Now, let's determine the value of the integral for those values of p.

Using the result from the integral evaluation:

∫(0 to 1) 1/x^p dx = lim(b→0) (b^(p+1) - 1) / (p+1).

Substituting b = 0:

∫(0 to 1) 1/x^p dx = lim(b→0) (0^(p+1) - 1) / (p+1)

                              = -1 / (p+1).

Therefore, the value of the integral for p > -1 is -1 / (p+1).

Thee flow rate is 0.486 m³/s and the head at the operating point is 8.85 m.

Reservoir B to reservoir A with the help of a pump at C.Diameter = 0.5 M Length = 1 km

Friction coefficient, f, can be taken as 0.02Hpump = 20 - 20Q².

Total head loss, Hl = (f L (V²))/ 2gd

= [(0.02 × 1000 × (V²))/ (2 × 9.81 × 500)]

= 0.204V²

According to the Bernoulli equation, the total head at point A and point C must be the same.

(p/ρg) + z + V²/2g = constant(z is elevation)

Pumping head = head loss + head at point A + friction lossHead loss (Hl) = (f L (V²))/ 2gd

According to the given data; we need to calculate the flow rate and the head at the operating point.

The formula to calculate the head loss is:

Hl = [(f L (V²))/ (2gd)]

Flow rate (Q) = [(2 ΔH) / (√(g × π² × d⁵ × Δp))]

Hpump = 20 - 20Q²

Head loss (Hl) = [(f L (V²))/ (2gd)]

Pumping head = head loss + head at point A + friction Loss

Let Q be the flow rate and H be the head at the operating point.So, pumping head = Head loss + Head at point A + Friction loss.

H = Hpump + Ha + Hl

Here, ΔH = H

= Head at point A - Head at point

B = 25 m

= 25000 mm

∆p = Head loss + Pumping head

(Hl + Hpump) = (20 - 20Q²) + 25000 + [(0.02 × 1000 × (V²))/ (2 × 9.81 × 500)]

Also, we know that, Q = A × V

Where,A = (π/4) × d²A

= (π/4) × (0.5)²

= 0.196 m²

So, Q = 0.196 V

We can replace the value of V in equation (1) and get the value of Q.∆p = 25020 + 0.204V² - 20Q² ----------- (1)

Hpump= 20-20Q²

= 20 - 20(Q/2) × (Q/2)

Hpump = 20 - 5Q²

Therefore, Δp = 25020 + 0.204V² - 5Q²

Substitute V = Q / 0.196 in Δp equation.

Δp = 25020 + 0.204 (Q/0.196)² - 5Q²

On differentiating this equation,

we get;0 = 0.204 × (1/0.196) × (Q/0.196) - 10QdΔp / dQ

= 0.204 / 0.196 Q - 10Q

= 1.041Q - 10Q

At equilibrium, dΔp / dQ = 0.

So, 1.041Q - 10Q = 0

=> Q = 0.486 m³/s

The head at the operating point,H = 20 - 20Q²

= 20 - 20 (0.486 / 2) × (0.486 / 2)

= 8.85 m (approx)

Hence, the flow rate is 0.486 m³/s and the head at the operating point is 8.85 m.

The rate of change of p with respect to q, when q = 2 and f = 6, is -0.375.

To find the rate of change of p with respect to q, we need to differentiate the lens equation with respect to q. Let's start by rearranging the equation:

1/f = 1/p + 1/q

To differentiate both sides, we use the reciprocal rule:

-1/f^2 * df/dq = -1/p^2 * dp/dq - 1/q^2

Since we are interested in finding the rate of change of p with respect to q (dp/dq), we rearrange the equation to solve for it:

dp/dq = (-1/p^2 * -1/q^2) * (-1/f^2 * df/dq)

Substituting the given values f = 6 and q = 2:

dp/dq = (-1/p^2 * -1/2^2) * (-1/6^2 * df/dq)

= (-1/p^2 * -1/4) * (-1/36 * df/dq)

= (1/p^2 * 1/4) * (1/36 * df/dq)

= df/dq * 1/(4p^2 * 36)

Since we are only interested in the rate of change when q = 2 and f = 6, we substitute these values:

dp/dq = df/dq * 1/(4 * 6^2 * 36)

= df/dq * 1/(4 * 36 * 36)

= df/dq * 1/5184

Therefore, when q = 2 and f = 6, the rate of change of p with respect to q is -0.375 (since dp/dq is negative).

Let us consider two cases:

CASE 1: f is decreasing on I ⇒ f′(x) ≤ 0 for all x ∈ I.Let f be decreasing on the interval I.

Thus, if a, b are two points in I such that a < b, then f(a) > f(b).We will now prove that f′(x) ≤ 0 for all x ∈ I. Consider any point c ∈ I.

Thus, for all x in I such that x > c, we have (x − c) > 0.

Also, by the definition of the derivative, we know that f′(c) = limh→0 (f(c + h) − f(c))/h. Thus, we can say that f(c + h) − f(c) ≤ 0, for all h > 0.

Hence, f′(c) ≤ 0.

We have proved the “if” part of the statement.

CASE 2: f′(x) ≤ 0 for all x ∈ I ⇒ f is decreasing on I. Let f′(x) ≤ 0 for all x ∈ I.

Thus, for any two points a, b in I such that a < b, we have f(b) − f(a) = f′(c)(b − a) for some c between a and b.

By the given condition, we know that f′(c) ≤ 0 and b − a > 0.

Thus, f(b) − f(a) ≤ 0, which means that f(a) ≥ f(b). We have proved the “only if” part of the statement.

a.)the initial estimate of the number of passengers infected with greyscale is -150.

b.) there is no maximum point for the infection rate in this case.

a. To estimate the initial number of passengers infected with greyscale, we need to find the value of g(t) when t is close to 0. However, since the function provided does not explicitly state the initial condition, we can assume that it represents the cumulative number of passengers infected with greyscale over time.

Therefore, to estimate the initial number of infected passengers, we can calculate the limit of the function as t approaches negative infinity:

lim(t→-∞) g(t) = lim(t→-∞) (-150/(1+e^(5-0.5t)))

As t approaches negative infinity, the exponential term e^(5-0.5t) will tend to 0, making the denominator 1+e^(5-0.5t) approach 1.

So, the estimated initial number of passengers infected with greyscale would be:

g(t) ≈ -150/1 = -150

Therefore, the initial estimate of the number of passengers infected with greyscale is -150. However, it's important to note that negative values do not make sense in this context, so it's possible that there might be an error or misinterpretation in the given function.

b. To find when the infection rate of greyscale is the greatest, we need to determine the maximum point of the function g(t). Since the function represents the cumulative number of infected passengers, the infection rate can be thought of as the derivative of g(t) with respect to t.

To find the maximum point, we can differentiate g(t) with respect to t and set the derivative equal to zero:

[tex]g'(t) = 150e^{(5-0.5t)(0.5)}/(1+e^{(5-0.5t))^{2 }}= 0[/tex]

Simplifying this equation, we get:

[tex]e^{(5-0.5t)(0.5)}/(1+e^{(5-0.5t))^2} = 0[/tex]

Since the exponential term e^(5-0.5t) is always positive, the denominator (1+e^(5-0.5t))^2 is always positive. Therefore, for the equation to be satisfied, the numerator (0.5) must be equal to zero.

0.5 = 0

This is not possible, so there is no maximum point for the infection rate in this case.

In summary, the infection rate of greyscale does not have a maximum point according to the given function. It's important to note that the absence of a maximum point may be due to the specific form of the function provided, and it's possible that there are other factors or considerations that could affect the infection rate in a real-world scenario.

The value of K is given as k = -54 / 55

Given f(y) = ky + 5 for 0 ≤ y ≤ 10, we want to find a constant k such that f(y) is a valid PMF.

To do this, we need to sum the probabilities for y from 0 to 10 and set the sum equal to 1.

∑(ky + 5) for y = 0 to 10 = 1

This becomes:

k∑y + ∑5 = 1

where ∑y is the sum of all y from 0 to 10, and ∑5 is the sum of 5 added 11 times (for each y from 0 to 10).

∑y = 0 + 1 + 2 + ... + 10 = 55

∑5 = 5 * 11 = 55

Plugging these into the equation:

k55 + 55 = 1

k55 = 1 - 55

k*55 = -54

k = -54 / 55

The function of y is a PMF

The solution using  Laplace transform is y(t) = (1/6) + (1/3)e^(-t) - (1/2)e^(-2t)cos(√2t) - (√2/3)e^(-2t)sin(√2t).

Let's denote the Laplace transform of y(t) as Y(s), where s is the Laplace variable. Applying the Laplace transform to the equation, we have:

L{y(t)} = L{1/6} + L{1/3 e^(-t)} - L{1/2 e^(-2t) cos(√2t)} - L{√2/3 e^(-2t) sin(√2t)}

Using the properties of Laplace transforms and the table of Laplace transforms, we can find the transforms of each term:

L{1/6} = 1/6 * L{1} = 1/6 * 1/s = 1/6s

L{1/3 e^(-t)} = 1/3 * L{e^(-t)} = 1/3 * 1/(s + 1)

L{1/2 e^(-2t) cos(√2t)} = 1/2 * L{e^(-2t) cos(√2t)} = 1/2 * 1 / (s + 2)^2 - √2^2

L{√2/3 e^(-2t) sin(√2t)} = √2/3 * L{e^(-2t) sin(√2t)} = √2/3 * √2 / ((s + 2)^2 + (√2)^2)

Now, let's substitute these results back into the Laplace transform equation:

Y(s) = 1/6s + 1/3(s + 1) - 1/2 * 1 / (s + 2)^2 - √2^2 - √2/3 * √2 / ((s + 2)^2 + (√2)^2)

To solve for Y(s), we need to simplify this expression. Combining the fractions, we have:

Y(s) = (1/6s) + (1/3s) + (1/3) - 1/2 * 1 / (s + 2)^2 - √2/3 * √2 / ((s + 2)^2 + (√2)^2)

Now, we can find the inverse Laplace transform of Y(s) to obtain the solution y(t). However, note that we also need to consider the initial condition y'(0) = 0.

Taking the inverse Laplace transform, we have:

y(t) = (1/6) + (1/3)e^(-t) - (1/2)e^(-2t)cos(√2t) - (√2/3)e^(-2t)sin(√2t)

This is the solution to the given differential equation with the initial condition y'(0) = 0.

The area of the new triangle is 100 square centimeters.

Let's assume the dimensions of the smaller triangle are base b and height h. The area of the smaller triangle is given as 25 square centimeters, so we have (1/2) * b * h = 25.

Now, considering the new triangle, the dimensions are two times the smaller triangle, so the base of the new triangle is 2b and the height is 2h.

The formula for the area of a triangle is (1/2) * base * height. Substituting the values, we get (1/2) * (2b) * (2h) = 2 * (1/2) * b * h = 2 * 25 = 50 square centimeters.

Therefore, the area of the new triangle is 50 square centimeters.

To determine a trade price that would allow for trade,  we need to consider the comparative advantage of each institution in producing paintballs and Hawthorne Hand Wipes.

Let's calculate the labor requirements for each product in terms of workers per ton: For Greendale: 1 ton of paintballs requires 10 workers.

1 ton of Hawthorne Hand Wipes requires 5 workers. For City College: 1 ton of paintballs requires 30 workers. 1 ton of Hawthorne Hand Wipes requires 10 workers.Based on these labor requirements, we can see that Greendale is relatively more efficient in producing paintballs since it requires fewer workers compared to City College. On the other hand, City College is relatively more efficient in producing Hawthorne Hand Wipes since it requires fewer workers compared to Greendale. To facilitate trade, a mutually beneficial trade price would be one that reflects the comparative advantage of each institution. Since City College is more efficient in producing Hawthorne Hand Wipes, they should specialize in producing wipes and export them to Greendale. In return, Greendale, being more efficient in producing paintballs, should specialize in paintball production and export them to City College.

The trade price should be set in a way that both institutions find it beneficial to trade. The specific value of the trade price would depend on various factors such as production costs, market conditions, and the preferences of Greendale and City College. Therefore, the suggested trade price would depend on the specific circumstances and cannot be determined without additional information. Please provide a specific value for the trade price, and I can further analyze the implications of that price on trade between Greendale and City College.

(b) In this particular case, the power method will not produce meaningful results, and the eigenvalues and eigenvectors of matrix A cannot be accurately determined using this method.

To compute the iterations using the power method, we start with an initial vector u₀ and repeatedly multiply it by the matrix A, normalizing the result at each iteration. The eigenvalue corresponding to the dominant eigenvector will converge as we perform more iterations.

(a) Computing u₁, u₂, u₃, and u using the power method:

Iteration 1:

[tex]u₁ = A * u₀ = [[1 2] [-1 -1]] * [1, 1] = [3, -2][/tex]

Normalize u₁ to get[tex]u₁ = [3/√13, -2/√13][/tex]

Iteration 2:

[tex]u₂ = A * u₁ = [[1 2] [-1 -1]] * [3/√13, -2/√13] = [8/√13, -5/√13][/tex]

Normalize u₂ to get u₂ = [8/√89, -5/√89]

teration 3:

[tex]u₃ = A * u₂ = [[1 2] [-1 -1]] * [8/√89, -5/√89] = [19/√89, -12/√89][/tex]

Normalize u₃ to get u₃ = [19/√433, -12/√433]

The iterations u₁, u₂, and u₃ have been computed.

(b) The power method will fail to converge in this case because the given matrix A does not have a dominant eigenvalue. In the power method, convergence occurs when the eigenvalue corresponding to the dominant eigen vector is greater than the absolute values of the other eigenvalues. However, in this case, the eigenvalues of matrix A are 2 and -2. Both eigenvalues have the same absolute value, and therefore, there is no dominant eigenvalue.

Without a dominant eigenvalue, the power method will not converge to a single eigenvector and eigenvalue. Instead, the iterations will oscillate between the two eigenvectors associated with the eigenvalues of the same magnitude.

A positive (+) correlation is when option c) X increases, Y increases. A negative (-) correlation is when option a) X decreases, Y decreases.

In a positive correlation, as X increases, Y also increases. This means that there is a consistent and direct relationship between the two variables. For example, if we consider X as the amount of studying done by students and Y as their test scores, a positive correlation would indicate that as students increase their studying efforts (X), their test scores (Y) also increase.

In a negative correlation, as X decreases, Y also decreases. This indicates an inverse relationship between the two variables. For instance, if we consider X as the amount of hours spent watching TV and Y as the level of physical activity, a negative correlation would suggest that as TV viewing time decreases (X), the level of physical activity (Y) also decreases.

The distance between the points (6, -1) and (3, 4) is √34 or approximately 5.83 units.

To calculate the distance between two points on a Cartesian plane, you can use the Euclidean distance formula. The formula is the following:

d = √((x₂ - x₁)² + (y₂ - y₁)²)

Where (x₁, y₁) and (x₂, y₂) are the coordinates of the two points.

Applying the formula to the points (6, -1) and (3, 4), we have:

d = √((3 - 6)² + (4 - (-1))²)
