There are no values of k that make the linear system consistent.
To determine the values of k for which the linear system is consistent, we need to check if the system of equations has a unique solution, infinitely many solutions, or no solution.
The given system of equations is:
8x1 - 7x2 = 2
12x1 + kx2 = -1
We can solve this system using various methods, such as substitution or elimination. Let's use the elimination method to simplify the system.
To eliminate x2, we can multiply equation 1 by k:
8kx1 - 7kx2 = 2k
Now, we can subtract equation 2 from equation 3:
(8k - 12)x1 + (-7k - k)x2 = (2k + 1)
Simplifying equation 4, we have:
(8k - 12)x1 - 8kx2 = 2k + 1
Now, for the system to be consistent, the coefficient of x1 and the coefficient of x2 in the resulting equation should be the same.
Comparing the coefficients, we get:
8k - 12 = 0 (coefficient of x1)
-8k = -1 (coefficient of x2)
Solving the first equation:
8k - 12 = 0
8k = 12
k = 12/8
k = 3/2
Now, substitute the value of k in the second equation to check if it is satisfied:
-8k = -1
-8(3/2) = -1
-12 = -1
The equation -12 = -1 is false. Therefore, there are no values of k for which the linear system is consistent.
In conclusion, there are no values of k that make the given linear system consistent.

Enter the result as a single logarithm with a coefficient of 1. log9 (12x^4) - logg (5x^) = ____________
The expression [tex]log9(12x^4) - logg(5x^?)[/tex] can be simplified by combining the logarithms into a single logarithm with a coefficient of 1.
To simplify the expression log9(12x^4) - logg(5x^?), we can apply the logarithmic property of subtraction, which states that loga(b) - loga(c) = loga(b/c). Using this property, we can rewrite the expression as a single logarithm.
First, let's simplify the expression log9(12x^4). Since the base of the logarithm is 9, we can rewrite it as log(12x^4) / log(9).
Next, let's simplify the expression logg(5x^?). Since the base of the logarithm is g, we can rewrite it as log(5x^?) / log(g).
Combining these two expressions, we have:
log(12x^4) / log(9) - log(5x^?) / log(g).
To combine these logarithms into a single logarithm, we need a common base. Let's use the base 10. Applying the logarithmic property of division, we can rewrite the expression as:
log(12x^4) / log(9) - log(5x^?) / log(g) = (log(12x^4) - log(5x^?)) / log(9g).
Finally, we simplify the numerator by applying the logarithmic property of subtraction:
[tex]log(12x^4) - log(5x^?) = log((12x^4) / (5x^?)).[/tex]

to Find the analyticity region of the function and find it's derivate of the following functions (a) √Z²-2 (b) Sen (log z²) 20 Find the Taylor serie around zero for fuz) = 4+2² and compute the Convergence radius
(a) To find the analyticity region of the function f(z) = √(z² - 2), we need to determine where the function is well-defined. The square root function is defined for non-negative real numbers. In this case, the expression inside the square root, z² - 2, should be greater than or equal to zero.
z² - 2 ≥ 0
Solving the inequality:
z² ≥ 2
Taking the square root of both sides, while considering both the positive and negative roots:
z ≥ √2 or z ≤ -√2
Therefore, the analyticity region of the function f(z) = √(z² - 2) is all values of z greater than or equal to √2 or less than or equal to -√2.
(b) To find the derivative of the function f(z) = Sen(log z²), we can use the chain rule.
Let's break it down:
f(z) = Sen(log z²)
First, find the derivative of the inner function log z²:
d/dz (log z²) = 1 / (z²) * 2z = 2 / z
Now, find the derivative of Sen(u), where u = log z²:
d/dz (Sen(u)) = cos(u) * du/dz
Substituting the value of u:
d/dz (Sen(log z²)) = cos(log z²) * (2 / z)
Therefore, the derivative of the function f(z) = Sen(log z²) is cos(log z²) * (2 / z).
(c) To find the Taylor series around zero for the function f(z) = 4 + 2z², we need to find the derivatives of the function at zero and use them to construct the series.
Let's find the derivatives:
f(z) = 4 + 2z²
f'(z) = 0 + 4z = 4z
f''(z) = 0 + 4 = 4
f'''(z) = 0
All higher-order derivatives will also be zero.
Now, let's construct the Taylor series around zero using these derivatives:
f(z) = f(0) + f'(0)z + (f''(0)/2!)z² + (f'''(0)/3!)z³ + ...
Since the higher-order derivatives are zero, the series simplifies to:
f(z) = 4 + 0z + (4/2!)z² + 0z³ + ...
Simplifying further:
f(z) = 4 + 2z²
The Taylor series around zero for the function f(z) = 4 + 2z² is simply the original function itself.
To compute the convergence radius of the series, we can observe that the function f(z) = 4 + 2z² is a polynomial, and all polynomials have an infinite convergence radius. Therefore, the convergence radius for this series is infinite.
In conclusion, to Find the analyticity region of the function and find it's derivate of the following functions the Taylor series around zero for the function f(z) = 4 + 2z² is 4 + 2z², and its convergence radius is infinite.

Given that P(B AND A) = 0.04 and P(A) = 0.18, what is P(BA)?
P(BA) is the conditional probability of event B given that event A has occurred approximately 0.04
P(BA), we need to know the individual probabilities of events A and B, as well as the probability of the intersection of events A and B.
P(B AND A) = 0.04
P(A) = 0.18
We can use the formula for the intersection of two events:
P(BA) = P(B AND A) = P(A) × P(B | A)
P(B | A) is the conditional probability of event B given that event A has occurred.
To calculate P(B | A), we can rearrange the formula as:
P(B | A) = P(B AND A) / P(A)
Putting in the given values:
P(B | A) = 0.04 / 0.18 ≈ 0.2222
Now we can calculate P(BA) using the formula:
P(BA) = P(A) × P(B | A)
= 0.18 × 0.2222
≈ 0.04
Therefore, P(BA) is approximately 0.04.

Farm workers are employed on a contract-to-contract basis. The contract lengths follow a normal distribution with a mean of 25 weeks and a variance of 36.
The variance is the average squared deviation of each value from the mean. It calculates how far each value in a group is from the mean, and then it squares the result of each of those calculations. Finally, it averages the sum of the squares to produce a figure that represents how varied the data is from the mean.
The variance formula is as follows:
Var(X) = (Σ (Xi - μ)^2) / (n - 1)
Where, X is a random variable representing the group data, μ is the mean of the group data, Xi is each value in the group data, Σ is the sum of all Xi values, and n is the number of values in the group data.

According to given information, the probability that a contract will last between 15 and 35 weeks is `0.905`.
To compute the probability that a contract will last between 15 and 35 weeks, we must utilize the standard deviation for the normal distribution.
To solve for the probability of a normal distribution, we use the formula `z = (x - μ) / σ`, where `x` is the value we are looking for, `μ` is the mean, and `σ` is the standard deviation.
We can compute the standard deviation using the variance, which is the square of the standard deviation, which is `σ^2`.
To begin, we first find the standard deviation. `σ = sqrt(36) = 6`.
Next, we will calculate the `z-scores` for 15 and 35.
[tex]`z1 = (15 - 25) / 6 = -10 / 6 = -1.67`[/tex]
and [tex]`z2 = (35 - 25) / 6 = 10 / 6 = 1.67`[/tex].
Now we can use the `Z-table` to find the probabilities that correspond to `z1` and `z2`. We can see that the probability of `z1` is `0.0475` and the probability of `z2` is `0.9525`.
Finally, to obtain the probability that a contract will last between 15 and 35 weeks, we must subtract the probabilities corresponding to `z1` from `z2`.
[tex]`P(15 ≤ X ≤ 35) = P(Z ≤ 1.67) − P(Z ≤ −1.67) = 0.9525 − 0.0475 = 0.905`[/tex].
Therefore, the probability that a contract will last between 15 and 35 weeks is `0.905`.

Step-by-step explanation:
The equation is in slope-intercept form, which is y = mx + b.
To graph the line, first we have to find the slope, m, and the y- intercept, b.
So, the slope is 2 and the y- intercept is 1.
We can graph this, beginning with the y- intercept, 1. The y- intercept is always on the y axis, so the (x) value will always be zero.
Plot a point at (0, 1).
Next, add more points using the slope. The slope is 2, or [tex]\frac{2}{1}[/tex]. Start at the point we have made on the y axis. The slope equals the [tex]\frac{rise}{run}[/tex]. We can rise 2 units, then run one more unit to the right. If the slope is negative, the run goes to the left. However, in this case, the slope is positive, to it slants to the right.
We end on point (1, 3). We can continue this path infinitely, some other points on the graph could be (2, 5), (3, 7), (4, 9) and (5, 11).

For the functions f(x) = 2x3- 3 and g(x) = 4x + 4, find (fog)(0) and (gºf)(0)
For the functions f(x) = 2x3- 3 and g(x) = 4x + 4, (gºf)(0) = g(f(0)) = g(-3) = -8.
To find (fog)(0), we need to evaluate the composition of functions f and g at x = 0.
First, we find g(0):
g(0) = 4(0) + 4 = 4.
Next, we substitute g(0) into f:
f(g(0)) = f(4).
Now, we find f(4):
f(4) = 2(4)^3 - 3 = 2(64) - 3 = 128 - 3 = 125.
Therefore, (fog)(0) = f(g(0)) = f(4) = 125.
To find (gºf)(0), we need to evaluate the composition of functions g and f at x = 0.
First, we find f(0):
f(0) = 2(0)^3 - 3 = -3.
Next, we substitute f(0) into g:
g(f(0)) = g(-3).
Now, we find g(-3):
g(-3) = 4(-3) + 4 = -12 + 4 = -8.
Therefore, (gºf)(0) = g(f(0)) = g(-3) = -8.

A system is of the form x2=A+f(t) must be 22 and the particular solution to the system in (1) The general solution to the system is (u) If the initial value of the system is (0) - 6 find the solution to the IVP (d) Consider the system of equations = -21; + 1 2 = -1 The system has a repeated eigenvalue of -1, and Fire is one solution to the system. Use the given eigenvector to find the second linearly independent solution to the system.
The solution to a system of the type x2=A+f(t) must be 22 and is given in:
(a) Eigenvalues: λ = -2, 11. Eigenvectors: (1, 1), (-1, 1).
(b) Particular solution: [tex]\begin{equation}x = -\frac{1}{13}e^{-2t} + \frac{1}{13}e^{11t} + f(t)[/tex]
(c) General solution: [tex]\begin{equation}x = c_1e^{-2t} + c_2e^{11t} - \frac{1}{13}e^{-2t} + \frac{1}{13}e^{11t}[/tex]
(d) Second linearly independent solution: x = 22t - 23.
Here is the explanation :
(a) The system is of the form x' = Ax + f(t), where A is a 2x2 matrix and f(t) is a 2x1 vector-valued function. The characteristic equation of A is |A - λI| = 0, which in this case gives us λ² + λ - 22 = 0. The eigenvalues are λ = -2 and λ = 11. The eigenvectors corresponding to these eigenvalues are (1, 1) and (-1, 1), respectively.
(b) The particular solution to the system in (a) is given by [tex]\begin{equation}x = c_1e^{-2t} + c_2e^{11t} + f(t)[/tex].
The function f(t) must satisfy the initial conditions x(0) = (1, -6) and x'(0) = (-2, 1). Using these initial conditions, we can find [tex]c_1[/tex] and [tex]c_2[/tex] as follows:
[tex]\begin{equation}c_1 = \frac{1 - 6}{-2 - 11} = -\frac{1}{13}[/tex]
[tex]\begin{equation}c_2 = \frac{-2 + 1}{-2 - 11} = \frac{1}{13}[/tex]
Therefore, the particular solution to the system is
[tex]\begin{equation}x = -\frac{1}{13}e^{-2t} + \frac{1}{13}e^{11t} + f(t)[/tex]
(c) The general solution to the system is given by [tex]\begin{equation}x = c_1e^{-2t} + c_2e^{11t} + u[/tex], where u is a particular solution to the system. In this case, we have already found [tex]\begin{equation}u = -\frac{1}{13}e^{-2t} + \frac{1}{13}e^{11t}[/tex].
Therefore, the general solution to the system is [tex]\begin{equation}x = c_1e^{-2t} + c_2e^{11t} - \frac{1}{13}e^{-2t} + \frac{1}{13}e^{11t}[/tex].
(d) The system has a repeated eigenvalue of -1, and Fire is one solution to the system. The second linearly independent solution can be found using the method of variation of parameters. In this method, we assume that the second solution is of the form x = vt + w, where v and w are constants to be determined. Substituting this into the system gives us the following equations:
-2v + w = -21
v + 11w = -1
Solving these equations gives us v = 22 and w = -23. Therefore, the second linearly independent solution is x = 22t - 23.

please solve question 1 step by step and the others if u have time please
Let the each angle be x , 2x and 3x.
→ x + 2x + 3x = 5600
→ 8x = 5600
→ x = 5600/8
→ x = 700
the value of x is Rs.700.
Now, 2x = 2×700 = 1400
, 3x = 3×700 = 2100
Each one will get Rs.700 , Rs.1400 and Rs. 2100.
