Answer:
an =1/3*6^n-1
Step-by-step explanation:
You should plug in 2 for n in each equation, which, the correct one should give you 2. Then, to make sure, you plug in 3 in the equations that gave you 2.
Example:
an = 1/3 * 6 ^n-1
Plug in 2.
an = 1/3 * 6 ^2-1
an = 1/3 * 6 ^1
1/3 * 6 = 2
Step 2.
an = 1/3 * 6 ^3-1
an = 1/3 * 6 ^2
1/3 * 36 = 12

Answer:
See Explanation
Step-by-step explanation:
The question is not clear. However, I will treat the question as:
[tex](26)x = 1[/tex]
[tex](50)x = 1[/tex]
and:
[tex](2^6)^x = 1[/tex]
[tex](5^0)^x = 1[/tex]
Solving: [tex](26)x = 1[/tex] and [tex](50)x = 1[/tex]
[tex](26)x = 1[/tex]
Divide both sides by 26
[tex]x = \frac{1}{26}[/tex]
[tex](50)x = 1[/tex]
Divide both sides by 50
[tex]x = \frac{1}{50}[/tex]
Solving [tex](2^6)^x = 1[/tex] and [tex](5^0)^x = 1[/tex]
[tex](2^6)^x = 1[/tex]
Express 1 as 2^0
[tex](2^6)^x = 2^0[/tex]
Remove bracket
[tex]2^{6x} = 2^0[/tex]
Cancel out 2
[tex]6x = 0[/tex]
Divide both sides by 6
[tex]x = \frac{0}{6}[/tex]
[tex]x = 0[/tex]
[tex](5^0)^x = 1[/tex]
Express 1 as 5^0
[tex](5^0)^x = 5^0[/tex]
Cancel out 5^0
[tex]x = 1[/tex]
Diagonalization of Symmetric Matrices Example 1: Consider the matrix. -5] A = 3 -5 3 a) Find the eigenvalues A₁, A₂ of A and find a basis for each eigenspace. = b) Find an orthonormal basis {u₁, u2} for R2 of eigenvectors of A (where Au₁ Au₂ = X₂U₂). A₁u₁ and c) Is A diagonalizable? If A is diagonalizable, find matrices P and D such that A = PDP-¹ d) Plot the eigenspaces of A using the bases found in part a). X2 4 2 X1 -4 2 -2 -4 2
For the given matrix A, the eigenvalues are A₁ = 4 and A₂ = -6. The matrix A is diagonalizable since it has two linearly independent eigenvectors. The diagonal form of A can be obtained as D = [[4, 0], [0, -6]], and the corresponding matrix of eigenvectors can be expressed as P = [[2, -1], [1, 2]].
To perform diagonalization of the symmetric matrix A, we find the eigenvalues A₁ = -6 and A₂ = 4, and their corresponding eigenvectors. We then normalize the eigenvectors to obtain an orthonormal basis {u₁, u₂} for R². A is diagonalizable, and by using the eigenvectors, we construct matrices P and D such that A = PDP⁻¹. Finally, we plot the eigenspaces using the bases found.
a) To find the eigenvalues A₁ and A₂, we solve the characteristic equation |A - λI| = 0, where I is the identity matrix. The characteristic equation for A yields (λ + 6)(λ - 4) = 0, giving A₁ = -6 and A₂ = 4. To find the eigenvectors, we substitute each eigenvalue into the equation (A - λI)u = 0 and solve for u. For A₁ = -6, we obtain the eigenvector u₁ = [-2, 1]. Similarly, for A₂ = 4, we find the eigenvector u₂ = [1, 2].
b) To obtain an orthonormal basis for R² using the eigenvectors, we normalize u₁ and u₂. The normalized vectors are u₁ = [-2/√5, 1/√5] and u₂ = [1/√5, 2/√5].
c) Since we have two linearly independent eigenvectors, A is diagonalizable. We can construct the diagonal matrix D using the eigenvalues A₁ and A₂ as its diagonal elements, and the matrix P with the eigenvectors as its columns. Thus, A = PDP⁻¹.
d) To plot the eigenspaces, we use the bases found in part a). The eigenspace corresponding to A₁ = -6 is spanned by the vector u₁, and the eigenspace for A₂ = 4 is spanned by the vector u₂. Using these bases, we can visualize the eigenspaces in the coordinate plane.

Shanna deposit 11,500 and leaves the funds in her account for 14 years how much will she have if the interest rate of the bank offered 4.9%
Hello!
This is a problem about interest rates.
Since we are not given the "[tex]n[/tex]" value, how many times this interest applies per time period, we can assume that we are most likely dealing with simple interest with an annual interest rate.
The simple interest formula is as follows,
[tex]A=P(1+rt)[/tex]
Where [tex]A[/tex] is the total amount, [tex]P[/tex] is the initial principal balance, [tex]r[/tex] is the annual interest rate, and [tex]t[/tex] is time in years.
Since we are given all this information, we can just solve after converting the interest rate of 4.9% to a decimal, which is 0.049.
[tex]A=11500(1+0.049*14)[/tex]
[tex]A=11500(1.686)[/tex]
[tex]A=19389[/tex]
So at the end of the 14th year, Shanna will have $19,389 in her account.

A segment in the complex plane has a midpoint at -1+i. If the segment has an endpoint at -5-7i, what is the other endpoint? -9-15i
Given that a segment in the complex plane has a midpoint at -1+i. If the segment has an endpoint at -5-7i, we need to find the other endpoint.
To find the other endpoint, we can use the midpoint formula which states that the midpoint of a segment is the average of the endpoints of the segment. Let the other endpoint be represented by the complex number z. Then, we have:-1 + i = (-5 - 7i + z)/2Multiplying both sides by 2, we get:-2 + 2i = -5 - 7i + zSimplifying the equation by moving the known values to the left-hand side, we have:z = -2 + 2i + 5 + 7iCombining like terms, we get:z = 3 + 9iTherefore, the other endpoint is 3 + 9i. Thus, the correct option is (D) 3 + 9i.
To find the other endpoint of the segment in the complex plane, we can use the midpoint formula. The midpoint formula states that the midpoint between two complex numbers, z₁ and z₂, is given by:
Midpoint = (z₁ + z₂) / 2
We are given that the midpoint is -1 + i and one endpoint is -5 - 7i. Let's denote the other endpoint as z₂. Using the midpoint formula, we can write:
-1 + i = (-5 - 7i + z₂) / 2
To isolate z₂, we can multiply both sides of the equation by 2:
2(-1 + i) = -5 - 7i + z₂
To simplifying, we have:
-2 + 2i = -5 - 7i + z₂
Now, let's isolate z₂ by subtracting -5 - 7i from both sides:
-2 + 2i + 5 + 7i = z₂
Combining like terms, we get: 3 + 9i = z₂
Therefore, the other endpoint of the segment in the complex plane is given by -9 - 15i.

The given information is that in the complex plane, a segment has its midpoint at -1+i. The segment has an endpoint at -5-7i. It is asked to find the other endpoint of the segment.
Thus, the other endpoint of the segment is -9 + 9i.
The midpoint of the segment is given as follows:
Midpoint = (endpoint1 + endpoint2) / 2
-1+i = (-5-7i + endpoint2) / 2
Multiplying both sides of above equation by 2, we get:
-2 + 2i = -5 - 7i + endpoint2
endpoint2 = -2 + 2i + 5 + 7i
endpoint2 = -9 + 9i
Therefore, the other endpoint of the segment is -9 + 9i.
Thus, the answer for this question is -9+9i.

The function f(x) is discontinuous at x = 0 and x = 1.To determine the points of discontinuity, we need to look at the different intervals defined by the function.
At x = 0, the function has different definitions for the left and right sides of the point. For x < 0, f(x) = x + 3, and for x ≥ 0 and x ≤ 1, f(x) = 3x^2. Therefore, at x = 0, f(x) is discontinuous. It is continuous from the left (approaching from x < 0) and from the right (approaching from x > 0).
At x = 1, the function has different definitions for the left and right sides of the point. For x ≤ 1, f(x) = 3x^2, and for x > 1, f(x) = 3 - x. Therefore, at x = 1, f(x) is discontinuous. It is continuous from the left (approaching from x ≤ 1) and from the right (approaching from x > 1).

Determine whether there is a significant difference in the pattern of rankings for the 26 American and 41 European male tennis players included in the top-100 seeded players on the pro-tennis tour.
To determine whether there is a significant difference in the pattern of rankings for the 26 American and 41 European male tennis players included in the top-100 seeded players on the pro-tennis tour, a statistical analysis can be conducted.
Statistical analysis would include a two-sample t-test or an ANOVA test to compare the means of the two groups (American and European players). If the p-value obtained is less than the level of significance (usually 0.05), then there is a significant difference between the pattern of rankings of the two groups.The rankings of players will also be taken into account. If there is a significant difference between the two groups, then further analysis can be done to determine the cause of the difference. Possible factors that could contribute to the difference include training regimes, genetics, playing surfaces, and mental preparation, among others.

There is no significant difference in the pattern of rankings between these two groups of players.
To determine whether there is a significant difference in the pattern of rankings for the 26 American and 41 European male tennis players included in the top-100 seeded players on the pro-tennis tour, we need to perform a statistical analysis using appropriate tests such as the t-test or ANOVA (Analysis of Variance).
The null hypothesis for this test would be that there is no significant difference in the pattern of rankings between the American and European male tennis players included in the top-100 seeded players on the pro-tennis tour.
The alternative hypothesis would be that there is a significant difference in the pattern of rankings between these two groups of players.
If the p-value obtained from the test is less than the chosen level of significance (usually 0.05), then we can reject the null hypothesis and conclude that there is a significant difference in the pattern of rankings for the American and European male tennis players included in the top-100 seeded players on the pro-tennis tour.
On the other hand, if the p-value is greater than the level of significance, we fail to reject the null hypothesis and conclude that there is no significant difference in the pattern of rankings between these two groups of players.

Question 5 Use the rules of differentiation to find the derivative of the function y (6x + 1)5 + 30x(6x + 1)ª (6x + 1)² (36x + 1) 1 X 6 No correct answer provided. = X x(6x + 1)5.
The derivative of the function y = x(6x + 1)⁵ is: dy/dx = (6x + 1)⁵ + 30x(6x + 1)⁴
To find the derivative of the given function, we can apply the rules of differentiation. Using the product rule, we differentiate each term separately and then add them together.
For the first term x, the derivative is simply 1.
For the second term (6x + 1)⁵, we apply the chain rule. The derivative of (6x + 1)⁵ with respect to x is 5(6x + 1)⁴ multiplied by the derivative of the inner function 6x + 1, which is 6.
Multiplying these derivatives together, we get (6x + 1)⁵ * 6 = 6(6x + 1)⁵.
For the third term x(6x + 1)⁴, we again apply the product rule. The derivative of x is 1, and the derivative of (6x + 1)⁴ is 4(6x + 1)³ multiplied by the derivative of the inner function 6x + 1, which is 6.
Multiplying these derivatives together, we get x * 4(6x + 1)³ * 6 = 24x(6x + 1)³.
Finally, we add the derivatives of each term to get the derivative of the entire function: dy/dx = (6x + 1)⁵ + 30x(6x + 1)⁴.

The value of the line integral ∫c f · dr is -cos(1) i - sin(1) j + 1/6 k.
Evaluate the integral?
To evaluate the line integral ∫c f · dr, we need to substitute the given values of f(x, y, z) and r(t) into the integral expression.
[tex]f(x, y, z) = sin(x) i cos(y) j\ x(z) k[/tex]
[tex]r(t) = t^4 i - t^3 j + t k[/tex] , 0 ≤ t ≤ 1
The line integral becomes:
[tex]\int c f * dr = \int c (sin(x) i cos(y) j x(z) k) * (dx i + dy j + dz k)[/tex]
Substituting [tex]x = t^4,\ y = -t^3, and\ z = t:[/tex]
[tex]\int c f * dr = \int c (sin(t^4) i cos(-t^3) j (t^4)(t) k) * (4t^3 dt i - 3t^2 dt j + dt k)[/tex]
Simplifying the expression:
[tex]\int c f * dr = \int c (4t^3 sin(t^4) dt i - 3t^2 cos(t^3) dt j + t^5 dt k)[/tex]
Integrating each component separately:
[tex]\int c f * dr = (\int 0^1 4t^3 sin(t^4) dt) i - (\int 0^1 3t^2 cos(t^3) dt) j + (\int 0^1 t^5 dt) k[/tex]
Evaluating each integral:
[tex]\int c f * dr = [-(cos(t^4))][/tex] evaluated from 0 to [tex]1 i - [sin(t^3)][/tex] evaluated from 0 to [tex]1 j + [t^6/6][/tex] evaluated from 0 to 1 k
Simplifying the expression:
[tex]\int c f * dr = -cos(1) i - sin(1) j + 1/6 k[/tex]

A null and alternative hypothesis are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Hoi 3.1 Ha 3.1 What type of test is being conducted in this problem?
A. Two-tailed test
B. Left-tailed test
C. Right-tailed test
The given null and alternative hypotheses, Hoi 3.1 and Ha 3.1, indicate that the hypothesis test is a two-tailed test.
In hypothesis testing, the null hypothesis (Hoi) represents the claim or assumption that is being tested, while the alternative hypothesis (Ha) represents the opposing claim or the hypothesis that the researcher is trying to support. The directionality of the test is determined by the alternative hypothesis.
In this case, the null hypothesis is stated as Hoi 3.1, and the alternative hypothesis is stated as Ha 3.1. Without knowing the specific details of the hypotheses, it can be determined that the test is two-tailed based on the notation used. The presence of two distinct hypotheses (Hoi and Ha) indicates that the test considers both directions of the distribution.
A two-tailed test is used when the alternative hypothesis does not specify a particular direction of the effect or relationship being tested. It is designed to determine whether the observed results are significantly different from the null hypothesis in either the positive or negative direction.
Therefore, the correct answer is A. Two-tailed test.
