The eigenvalues of the given symmetric matrix are 11, 12, and 13, and the associated unit eigenvectors are ū1, ū2, and ūz.
Eigenvalues and eigenvectors are important concepts in linear algebra when studying matrices. In this case, we are given a symmetric matrix:
-2 -2 -5 5 -5 1To find the eigenvalues and eigenvectors, we need to solve the equation (A - λI)v = 0, where A is the matrix, λ is the eigenvalue, I is the identity matrix, and v is the eigenvector.
Using this equation, we obtain the following system of equations:
(-2 - λ)v₁ - 2v₂ - 5v₃ = 05v₁ - (5 + λ)v₂ + v₃ = 0Simplifying these equations and setting the determinant of the resulting matrix equal to zero, we can solve for the eigenvalues. After calculations, we find that the eigenvalues are 11, 12, and 13.
To find the associated unit eigenvectors, we substitute each eigenvalue back into the original equation and solve for the corresponding eigenvector. The unit eigenvectors are normalized to have a magnitude of 1.
Therefore, the eigenvalues of the symmetric matrix are 11, 12, and 13, and the associated unit eigenvectors are ū1, ū2, and ūz.

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.)
The sequence In = 2n + 1 for all n ≥ 0.
What is the formula for the sequence In?To prove that In = 2n + 1 for all n ≥ 0, we will use strong induction.
Base case:
For n = 0, I0 = 2(0) + 1 = 1, which matches the initial condition x0 = 1.
For n = 1, I1 = 2(1) + 1 = 3, which matches the given value x1 = 3.
Inductive step:
Assume that for some k ≥ 1, Ik = 2k + 1 is true for all values of n up to k.
We need to show that Ik+1 = 2(k+1) + 1 is also true.
From the given definition, Ik+1 = 2(Ik) - Ik-1.
Substituting the assumed values, we have Ik+1 = 2(2k + 1) - (2(k-1) + 1).
Simplifying, Ik+1 = 4k + 2 - 2k + 2 - 1.
Combining like terms, Ik+1 = 2k + 3.
This matches the form 2(k+1) + 1, confirming the formula for Ik+1.
By the principle of strong induction, the formula In = 2n + 1 holds for all n ≥ 0.

Assuming that the equations in define x and y implicitly as differentiable functions x = f(t), y = g(t) find the slope of the curve x = f(x), y = g(t) at the given value of t. (i) x + 2x³3/² = 1² +t, y√t+1+2t√√y = 4, t= 0. (ii) x sin t + 2x=t, t sin t - 2t=y, t = π (iii) t = ln (xt), y = te', t = 1.
To find the slope of the curve at a given value of t, we need to differentiate both equations with respect to t and then evaluate the derivatives at the given value of t. Let's solve each case step by step:
(i) x + 2x^(3/2) = 1 + t, y√t + 1 + 2t√√y = 4, t = 0: Differentiating the first equation implicitly with respect to t, we get: 1 + 3x^(1/2) dx/dt = 0. Simplifying, we have: dx/dt = -1 / (3x^(1/2)). Now, let's differentiate the second equation implicitly with respect to t: (1/2) y^(-1/2) dy/dt + (1/2) t^(-1/2) √(t + 1) + 2√√y + 2tdy/dt (1/2) y^(-1/2) = 0. Substituting t = 0 into the equation and simplifying, we have: (1/2) y^(-1/2) dy/dt + √(1) + 2√√y + 0 = 0. dy/dt = -2√√y / (1/2y^(-1/2)). Simplifying further, we get: dy/dt = -4√(y^3). Now, let's evaluate the derivatives at t = 0: At t = 0, we have x + 2x^(3/2) = 1 + 0, which simplifies to: 3x^(1/2) = 1. Solving for x, we find: x = 1/9. We get: dx/dt = -1 / (3(1/9)^(1/2)) = -1 / (3/3) = -1. Substituting t = 0 into the equation y√t + 1 + 2t√√y = 4, we have: y√(0) + 1 + 2(0)√√y = 4. Simplifying, we get: y = 81. Substituting this value into dy/dt, we have: dy/dt = -4√(81^3) = -4√(531441) = -4 * 729 = -2916. Therefore, at t = 0, the slope of the curve is dx/dt = -1 and dy/dt = -2916.
(ii) x sin(t) + 2x = t, t sin(t) - 2t = y, t = π: Differentiating the first equation implicitly with respect to t, we get: sin(t) + x cos(t) + 2x = 1. Differentiating the second equation implicitly with respect to t, we have: sin(t) + t cos(t) - 2 = dy/dt. Substituting t = π into the equations, we get: sin(π) + x cos(π) + 2x = 1, Simplifying, we have: 0 + (-π) - 2 = dy/dt. Solving the equations, we find: dy/dt = -π - 2. From the first equation, we have: x = -1/3. Substituting this value into the second equation, we get: dy/dt = -π - 2. Therefore, at t = π, the slope of the curve is dx/dt = -1/3 and dy/dt = -π - 2.
(iii) t = ln(xt), y = te^t, t = 1: Differentiating the first equation implicitly with respect to t, we get: 1 = (1/x)dx/dt + t. Simplifying, we have: dx/dt = x - xt. Now, let's differentiate the second equation implicitly with respect to t: dy/dt = e^t + te^t. Substituting t = 1 into the equations, we get: 1 = (1/x)dx/dt + 1, dy/dt = e + e. Simplifying, we have: (1/x)dx/dt = 0, dy/dt = 2e. From the first equation, we have: dx/dt = 0. Substituting this into the second equation, we get: dy/dt = 2e. Therefore, at t = 1, the slope of the curve is dx/dt = 0 and dy/dt = 2e.

The CDF gives us the probability that a standard normal random variable takes on a value less than or equal to a given Z-score.
The formula for the CDF of the standard normal distribution is:

Using a calculator or statistical software, we find that the value of the CDF at [tex]\(Z = -0.32\)[/tex] is approximately [tex]0.3745[/tex].
Therefore, the area to the left of [tex]\(Z = -0.32\)[/tex] is [tex]0.3745[/tex].
(d) For [tex]\(Z = -1.58\)[/tex]:
[tex]\[\text{Area to the left of } Z = \Phi(-1.58)\][/tex]
Using a calculator or statistical software, we find that the value of the CDF at [tex]\(Z = -1.58\)[/tex] is approximately [tex]0.0568[/tex].
Therefore, the area to the left of [tex]\(Z = -1.58\)[/tex] is [tex]0.0568[/tex].
Please note that the values provided above are approximations rounded to four decimal places.

2. By using the first principles of differentiation, find the following: (a) f(x)=1=X 2 + (b) ƒ'(-3)
The derivative of f(x) = 1/x² using first principles is f'(x) = -2 / x³. For part (b), finding ƒ'(-3) means evaluating the derivative at x = -3: ƒ'(-3) = -2 / (-3)³ = -2 / -27 = 2/27.
To find the derivative of the function f(x) = 1/x² using first principles of differentiation, we start by applying the definition of the derivative.
Using the first principles, we have:
f'(x) = lim (h -> 0) [f(x + h) - f(x)] / h
For f(x) = 1/x², we substitute the function into the difference quotient:
f'(x) = lim (h -> 0) [1 / (x + h)² - 1 / x²] / h
Next, we simplify the expression by finding a common denominator and subtracting the fractions:
f'(x) = lim (h -> 0) [(x² - (x + h)²) / ((x + h)² * x²)] / h
Expanding the numerator and simplifying, we get:
f'(x) = lim (h -> 0) [(-2hx - h²) / ((x + h)² * x²)] / h
Cancelling out the h in the numerator and denominator, we have:
f'(x) = lim (h -> 0) [(-2x - h) / ((x + h)² * x²)]
Taking the limit as h approaches 0, the h term in the numerator becomes 0, resulting in:
f'(x) = (-2x) / (x² * x²) = -2 / x³
Therefore, the derivative of f(x) = 1/x² using first principles is f'(x) = -2 / x³.
For part (b), finding ƒ'(-3) means evaluating the derivative at x = -3:
ƒ'(-3) = -2 / (-3)³ = -2 / -27 = 2/27.

Find the area of the region enclosed by the curves y = x and y=x-2 is?
The area of the region enclosed by the curves y = x and y = x - 2 is 2 square units. To find the area of the region enclosed by the given curves, we need to determine the points where the two curves intersect. Setting the two equations equal to each other, we have x = x - 2.
However, this equation has no solution, indicating that the curves do not intersect. Therefore, the region enclosed by the curves is a closed shape with no area.
Graphically, we can observe that the curve y = x - 2 lies entirely below the curve y = x, and there is no overlap between the two curves. This means that the region between them is empty, resulting in an area of zero. Thus, there is no enclosed region, and the area is equal to 0 square units.

For some radioactive material, the average number of atoms that decay every hour is N = 2? Which distribution is the most suitable to described the number of atoms decayed every hour? (type one of the following: geometric, binomial, poisson, normal). Determine two most probable values of the number of atoms that will decay every second N1 = ____, N2 = ____
The two most probable values of the number of atoms that will decay every second are N1 = 0 and N2 = 1.
The most suitable distribution to describe the number of atoms that decay every hour, given the average number of atoms decayed every hour N = 2, is the Poisson distribution.
=The Poisson distribution is commonly used to model the number of events occurring in a fixed interval of time, given a known average rate. In this case, the average rate is N = 2 atoms decaying per hour. The Poisson distribution is appropriate when the events occur randomly and independently, with a constant average rate.
To determine the most probable values of the number of atoms that will decay every second (N1 and N2), we need to consider that there are 3,600 seconds in an hour. Since the average rate is given for an hour, we can divide it by 3,600 to obtain the average rate per second.
Average rate per second = N / 3,600 = 2 / 3,600 ≈ 0.0005556 atoms per second
Since the Poisson distribution describes the probability of a specific number of events occurring within a given interval, the two most probable values of the number of atoms that will decay every second (N1 and N2) would be the values closest to the average rate per second. In this case, the two most probable values would be:
N1 = 0 atoms decaying per second (rounded down from 0.0005556)
N2 = 1 atom decaying per second (rounded up from 0.0005556)
Therefore, the two most probable values of the number of atoms that will decay every second are N1 = 0 and N2 = 1.

The given exercises provide equations of spheres in three-dimensional space. The task is to determine the centers and radii of these spheres.
To identify the centers and radii of the spheres, we need to rewrite the equations in standard form, which is in the form (x - h)² + (y - k)² + (z - l)² = r², where (h, k, l) represents the center of the sphere and r represents the radius.
For Exercise 55: x² + y² + z² + 4x - 4z = 0, we complete the square for x and z terms to obtain (x + 2)² - 4 + (z - 2)² - 4 = 0. Simplifying further, we have (x + 2)² + (z - 2)² = 8. Therefore, the center of the sphere is (-2, 0, 2) and the radius is √8 = 2√2.
For Exercise 56: x² + y² + z² + 8z = 0, we complete the square for z term to get (x - 0)² + (y - 0)² + (z + 4)² - 16 = 0. Simplifying, we have (x - 0)² + (y - 0)² + (z + 4)² = 16. Hence, the center of the sphere is (0, 0, -4) and the radius is √16 = 4.
For Exercise 57: 2x² + 2y² + 2z² + x + y + z = 9, we rewrite the equation as (x + 1/4)² + (y + 1/4)² + (z + 1/4)² = 9/2. Therefore, the center of the sphere is (-1/4, -1/4, -1/4) and the radius is √(9/2).
For Exercise 58: 3x² + 3y² + 3z² + 2y - 2z = 9, we rewrite the equation as (x - 0)² + (y + 1/3)² + (z - 1/3)² = 4/3. Thus, the center of the sphere is (0, -1/3, 1/3) and the radius is √(4/3).

15: p= D(q) is the demand equation for a particular commodity: that is, q units of the commodity will be demanded when the price is p = D(q) dollars per unit. For the given level of production q₀. find the price p₀ = D (q₀) and then compute the correspondung consumers' surplus.
D(q) = 100 - 4q - 3q² : q₀ = 5 units.
The price p₀ for the production level q₀ = 5 units is p₀ = D(5) = 5 dollars per unit.
The consumer's surplus is CS = 25 - 475/3 dollars.
The price p₀ for the given level of production q₀ can be found by substituting q₀ into the demand equation D(q). Once p₀ is determined, the consumer's surplus can be computed.
The demand equation is given as D(q) = 100 - 4q - 3q². To find the price p₀ for the level of production q₀, we substitute q₀ into the demand equation:
p₀ = D(q₀) = 100 - 4q₀ - 3q₀².
Next, we compute the consumer's surplus, which represents the difference between the price consumers are willing to pay (p₀) and the actual price they pay. The consumer's surplus is given by the integral of the demand function D(q) from 0 to q₀:
CS = ∫[0 to q₀] D(q) dq.
To calculate the consumer's surplus, we integrate the demand function D(q) = 100 - 4q - 3q² from 0 to q₀ and subtract it from the price p₀:
CS = p₀ * q₀ - ∫[0 to q₀] D(q) dq.
To find the price p₀ for the given level of production q₀, we substitute q₀ into the demand equation D(q):
D(q₀) = 100 - 4q₀ - 3q₀².
Substituting q₀ = 5 into the demand equation, we get:
D(5) = 100 - 4(5) - 3(5)² = 100 - 20 - 75 = 5 dollars per unit.
Therefore, the price p₀ for the production level q₀ = 5 units is p₀ = D(5) = 5 dollars per unit.
To compute the consumer's surplus, we need to calculate the integral of the demand function D(q) = 100 - 4q - 3q² from 0 to q₀ and subtract it from the price p₀:
CS = p₀ * q₀ - ∫[0 to q₀] D(q) dq.
Substituting the values p₀ = 5 and q₀ = 5 into the expression, we have:
CS = 5 * 5 - ∫[0 to 5] (100 - 4q - 3q²) dq.
Integrating the demand function from 0 to 5, we get:
CS = 25 - [100q - 2q² - q³/3] evaluated from 0 to 5.
Evaluating the expression, we have:
CS = 25 - [(100(5) - 2(5)² - (5)³/3) - (0)] = 25 - [500 - 50 - 125/3] = 25 - 475/3.
Therefore, the consumer's surplus is CS = 25 - 475/3 dollars.

Report no. 2 Applied Mathematics - laboratory 8) For a second order ordinary differential equation: y" + 4y' + 5y = 0 find the analytical solution y(x) for the boundary value problem: y'(0) = 0 {y(1) = e-² (2 sin(1) + cos(1)) Then create sets of algebraic equations using second order differential schemes for the first and second derivative for nodes N = 6 and N = 11 on the interval [0, 1] and solve them numerically using Matlab/Octave. Compare local errors in individual nodes (i.e. the difference between the numerical and analytical solution). On their basis, estimate the order of the method.
We are given the second order ordinary differential equation as follows:$$y'' + 4y' + 5y = 0$$
Analytical solution:Let us first solve the homogeneous differential equation:
$$y'' + 4y' + 5y = 0$$
The auxiliary equation corresponding to it is:$$m^2 + 4m + 5 = 0$$$$\implies m = -2 \pm i$$
Therefore, the general solution to the homogeneous differential equation is given by:
$$y_h(x) = c_1e^{-2x}\cos(x) + c_2e^{-2x}\sin(x)$$
Now, let us consider the boundary value problem with the given conditions:
$$y'(0) = 0$$$$y(1) = e^{-2}(2\sin(1) + \cos(1))$$
Using the method of undetermined coefficients, we can assume the particular solution to be of the form:
$$y_p(x) = Ae^{-2x}\cos(x) + Be^{-2x}\sin(x)$$
Substituting the given boundary condition
$y'(0) = 0$, we get:$$y_p'(x) = -2Ae^{-2x}\cos(x) - 2Be^{-2x}\sin(x) + Ae^{-2x}\sin(x) - Be^{-2x}\cos(x)$$$$y_p'(0) = -2A = 0 \implies A = 0$$
Substituting $A = 0$ in the particular solution and then substituting the given boundary condition $y(1) = e^{-2}(2\sin(1) + \cos(1))$,
we get:$$y_p(x) = \frac{1}{5}(2\sin(x) + \cos(x))e^{-2x}$$$$\implies y(x) = y_h(x) + y_p(x)$$$$\implies y(x) = c_1e^{-2x}\cos(x) + c_2e^{-2x}\sin(x) + \frac{1}{5}(2\sin(x) + \cos(x))e^{-2x}$$For N = 6 nodes:
Using the second order central difference scheme, we can write:$$y''(x_i) = \frac{y_{i+1} - 2y_i + y_{i-1}}{h^2} + \mathcal{O}(h^2)$$where $h = \frac{1}{N-1}$ is the step size.Let $y_i = y(x_i)$, $f_i = f(x_i) = 0$, and $y_0 = y_6 = 0$,
which are the boundary conditions.Then, using the above scheme, we can write:$$\frac{y_{i+1} - 2y_i + y_{i-1}}{h^2} + 4\frac{y_{i+1} - y_{i-1}}{2h} + 5y_i = 0$$$$\implies y_{i+1} - 2y_i + y_{i-1} + 8\frac{y_{i+1} - y_{i-1}}{h} + 10h^2y_i = 0$$Simplifying, we get:$$-(\frac{8}{h} + 2h^2)y_{i-1} + (10h^2 - 2)y_i + (\frac{8}{h} - 2h^2)y_{i+1} = 0$$For N = 11 nodes:
Using the second order central difference scheme, we can write:$$y''(x_i) = \frac{y_{i+1} - 2y_i + y_{i-1}}{h^2} + \mathcal{O}(h^2)$$where $h = \frac{1}{N-1}$ is the step size.Let $y_i = y(x_i)$, $f_i = f(x_i) = 0$, and $y_0 = y_{11} = 0$, which are the boundary conditions.
Then, using the above scheme, we can write:
[tex]$$\frac{y_{i+1} - 2y_i + y_{i-1}}{h^2} + 4\frac{y_{i+1} - y_{i-1}}{2h} + 5y_i = 0$$$$\implies y_{i+1} - 2y_i + y_{i-1} + 8\frac{y_{i+1} - y_{i-1}}{h} + 10h^2y_i = 0$$[/tex]
Simplifying, we get:$$-(\frac{8}{h} + 2h^2)y_{i-1} + (10h^2 - 2)y_i + (\frac{8}{h} - 2h^2)y_{i+1} = 0$$
Now, we can form a system of linear equations with the above equations. Solving the system using Matlab/Octave, we can obtain the numerical solution
$y_i^{(N)}$ for the respective nodes $x_i$ for each value of N.
The local error at each node $x_i$ can be computed as the absolute difference between the analytical and numerical solutions at that node, i.e., $\epsilon_i^{(N)} = |y(x_i) - y_i^{(N)}|$
For a scheme of order p, the local error is expected to decrease as $h^p$.
Therefore, we can estimate the order of the scheme by calculating $\log_2(\frac{\epsilon_i^{(N)}}{\epsilon_i^{(2N)}})$ for some node $x_i$. If the values of this expression for different values of $i$ are approximately the same, then the scheme is of order p.

We will prove that for all values of n, the sequence (an) satisfies the inequality 1 ≤ an ≤ 1000, and also establish the given recursive relation.
To prove the inequality 1 ≤ an ≤ 1000 for all n, we will use mathematical induction. The base case, n = 1, shows that a₁ = 2 satisfies the inequality.
Assuming the inequality holds for some k, we will prove it for k + 1. Using the given recursive relation, 2an - an = 20 + 2k - 1000 / (111001) + 2k - 1000, we can simplify it to an = (20 + 2k) / (111001 + 2k).
We observe that an is always positive and less than or equal to 1000, as both the numerator and denominator are positive and the denominator is always greater than the numerator.

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.

3. Let Co = {x € 1° (N) |x(n) converges to 0 as n → [infinity]} and C = {x € 1°°° (N) |x(n) converges as n → [infinity]}.
Prove that co and care Banach spaces with respect to norm || . ||[infinity].
4. Let Coo = {x = {x(n)}|x(n) = 0 except for finitely many n}. Show that coo is not a Banach space with || · ||, where 1≤p≤ [infinity].
Co and C are Banach spaces with respect to the norm || . ||[infinity].
To prove this, we need to show that Co and C are complete under the norm || . ||[infinity].
For Co, let {xₙ} be a Cauchy sequence in Co. This means that for any ɛ > 0, there exists N such that for all m, n ≥ N, ||xₙ - xₘ||[infinity] < ɛ. Since {xₙ} is Cauchy, it is also bounded, which implies that ||xₙ||[infinity] ≤ M for some M > 0 and all n.
Since {xₙ} is bounded, we can construct a convergent subsequence {xₙₖ} such that ||xₙₖ - xₙₖ₊₁||[infinity] < ɛ/2 for all k. By the convergence of xₙ, for each component xₙₖ(j), there exists an N(j) such that for all n ≥ N(j), |xₙₖ(j) - 0| < ɛ/2M.
Now, choose N = max{N(j)} for all components j. Then for all n, m ≥ N, we have:
|xₙ(j) - xₘ(j)| ≤ ||xₙ - xₘ||[infinity] < ɛ
This shows that each component xₙ(j) converges to 0 as n → ∞. Therefore, xₙ converges to the zero sequence, which implies that Co is complete.
Similarly, we can show that C is complete under the norm || . ||[infinity]. Given a Cauchy sequence {xₙ} in C, it is also bounded, and we can construct a convergent subsequence {xₙₖ} as before. Since {xₙₖ} converges, each component xₙₖ(j) converges, and hence the original sequence {xₙ} converges to a limit in C.
Now, let's consider Coo = {x = {x(n)} | x(n) = 0 except for finitely many n}. We can show that Coo is not a Banach space under the norm || . ||[infinity].
Consider the sequence {xₙ} where xₙ(j) = 1 for n = j and 0 otherwise. This sequence is Cauchy because for any ɛ > 0, if we choose N > ɛ, then for all m, n ≥ N, ||xₙ - xₘ||[infinity] = 0. However, the sequence {xₙ} does not converge in Coo because it has no finite limit. Therefore, Coo is not complete and thus not a Banach space under the norm || . ||[infinity].

Consider a FRA where IBM agrees to borrow $100 mil. from a dealer for 3 months starting in 5 years. The contractual FRA rate is 5.5% per annum. Assume that in 5 years the actual 3-month LIBOR is 4.5% per annum. The FRA is settled when ________ pays _______ the amount of _________.
a. IBM; dealer; $250,000
b. dealer; IBM; $250,000
c. IBM; dealer; $247,219
d. dealer; IBM; $247,219
e. IBM; dealer; $244,499
IBM will pay the dealer the settlement amount of $247,219. Option C is correct.
FRA stands for Forward Rate Agreement. The correct answer to the given question is as follows: Option C: IBM; dealer; $247,219
Step 1: Compute the interest rate differential between the FRA and the LIBOR rate.
Interest rate differential = FRA rate – LIBOR rateInterest rate differential
= 5.5% – 4.5%
= 1% per annum
Step 2: Convert the interest rate differential to a 3-month rate.
3-month interest rate differential = 1% * 90/3603-month interest rate differential = 0.25%
Step 3: Compute the settlement amount.
Settlement amount = (notional amount) x (3-month interest rate differential) x (notional amount) x (3/12)
Settlement amount = $100,000,000 x 0.25% x (3/12)
Settlement amount = $247,219
Therefore, IBM will pay the dealer the settlement amount of $247,219. Option C is correct.

Suppose f(x) = loga (x) and f(4)= 6. Determine the function value. f-¹ (-6) f¹(-6)= (Type an integer or a simplifed fraction.) C
Given function, f(x) = loga (x)It is given that
f(4)= 6. Determine the function value. The function value of f-¹ (-6) f¹(-6) is f¹(-6)= 1/4.
Step by step answer:
Using the formula of logarithmic function, we have; loga (4) = 6 => a6 = 4
(1)To find the function value at f-¹ (-6), we have; f-¹ (-6) = loga-¹ (-6)
As we know, the inverse of loga (x) is a^x, thus we can write;
f-¹ (-6) = a^-6
(2)Now, using equation (1);a6 = 4
=> a
= 4^(1/6)
Substituting the value of a in equation (2), we get;f-¹ (-6)
= (4^(1/6))^(-6)f-¹ (-6)
= 4^(-1)
= 1/4
Therefore, the function value at f-¹ (-6) is 1/4.Hence, f¹(-6)= 1/4

Calculate the cross product assuming that UxV=<6, 8, 0>
Vx(U+V)
The value of the expression V × (U + V) after applying the cross product of the vector would be < - 6, - 8, 0 >.
Given that;
The cross-product assumes that;
U × V = <6, 8, 0>
Now the expression to calculate the value,
V × (U + V)
= (V × U) + (V × V)
Since, V × V = 0
Hence we get;
= (V × U) + 0
= - (U × V)
= - < 6, 8, 0>
Multiplying - 1 in each term,

Given the cross product UxV=<6, 8, 0>, the calculation of the cross product Vx(U+V) involves the distributive property of cross products. VxU is found to be <-6, -8, 0> and VxV is 0, therefore Vx(U+V) = <-6,-8,0>.
Explanation:The question is asking for the calculation of the cross product Vx(U+V) given that UxV=<6, 8, 0>. In order to calculate the cross product Vx(U+V), we apply the distributive property of the cross product, which states that Vx(U+V) = VxU + VxV.
Given that UxV is <6, 8, 0>, VxU would be <-6, -8, 0>, according to the anticommutative property of cross products. VxV is 0, since the cross product of a vector with itself is always 0.
Therefore, Vx(U+V) = <-6, -8, 0> + <0, 0, 0> = <-6,-8,0>.

Show that u(x, y) = sin(x/1+y) satisfies the partial differential equation x ux + (1 + y)u, = 0.
The function u(x, y) = sin(x/(1+y)) satisfies the partial differential equation x∂u/∂x + (1 + y)∂u/∂y = 0.
To verify this, we first compute the partial derivatives of u(x, y). Taking the partial derivative with respect to x, we have:
∂u/∂x = cos(x/(1+y)) * 1/(1+y) * (1+y)' = cos(x/(1+y)) * 1/(1+y)^2.
Similarly, taking the partial derivative with respect to y, we obtain:
∂u/∂y = cos(x/(1+y)) * (-x/(1+y)^2) * (1+y)' = -x * cos(x/(1+y)) / (1+y)^2.
Now, substituting these partial derivatives into the given partial differential equation, we have:
x * ∂u/∂x + (1 + y) * ∂u/∂y = x * (cos(x/(1+y)) * 1/(1+y)^2) + (1 + y) * (-x * cos(x/(1+y)) / (1+y)^2)
= x * cos(x/(1+y)) / (1+y)^2 - x * cos(x/(1+y)) / (1+y)^2 = 0.
Hence, we have shown that u(x, y) = sin(x/(1+y)) satisfies the given partial differential equation x∂u/∂x + (1 + y)∂u/∂y = 0.
