find f(n) when n = 3k, where f satisfies the recurrence relation f(n) = 2f(n∕3) 4 with f(1) = 1.
Main Answer: The value of f(n) = 16(f(k))^4 when n = 3k.
Supporting Question and Answer:
How can we determine the value of f(n) when n = 3k using the given recurrence relation and initial condition?
By analyzing the given recurrence relation f(n) = 2f(n/3)^4 and the initial condition f(1) = 1, we can recursively calculate the value of f(n) for n = 3k. Using the recurrence relation, we can express f(n) in terms of f(n/3) and apply it iteratively. The value of f(n) when n = 3k is given by f(n) = 16(f(k))^4, where f(1) = 1 is used as the base case.
Body of the Solution:To find the value of f(n) when n = 3k, where f satisfies the recurrence relation f(n) = (2f(n/3))^4 with f(1) = 1, we can use the recurrence relation to recursively calculate the values of f(n).
Given that f(1) = 1, we can calculate the values of f(n) for n = 3, 9, 27, and so on.
f(3) = (2f(3/3))^4
= ((2f(1)))^4
= 2^4(1)^4
= 16
f(9) = (2f(3))^4
= (2(16))^4
= 1048576
f(27) =(2f(9))^4
= (2(1048576))^4
=(2097152)^4
Therefore, f(n) when n = 3k is given by:
f(3K) =16(f(k))^4
So, f(n) =16(f(k))^4 when n = 3k, where f satisfies the given recurrence relation and f(1) = 1.
Final Answer:Therefore, f(n) =16(f(k))^4 when n = 3k.

Find the center of mass of the areas formed by x+3=(y-1)^2; y=2, in coordinate axes
The center of mass of the region is (21/20, 10/3).
To find the center of mass of the area formed by the curve \(x+3=(y-1)^2\) ans the line y=2, we need to first find the area of the region and then find the coordinates of the center of mass.
To find the area , we integrate the curve between the y-values of 2 and 3:
\(A = \int\limits^3_2 [(y-1)^2 - 3] dy \\ = > \int\limits^3_2 (y^2 - 2y - 2) dy \\ = > [\frac{1}{3} y^3 - y^2 - 2y]_2^3\\ = > \frac{1}{3} (27 - 4 - 6) - \frac{1}{3} (8 - 4 - 4) = \frac{5}{3}\)
So , the area of the region is 5/3 square units.
To find the coordinates of the center of mass , we need to compute the moments about the x and y axes and divide by the total area:
\(Mx = \int\limits^3_2[(y-1)^2 - 3] * y dy \\ = > \int\limits^3_2 (y^3 - 3y^2 + 2y) dy \\ = > [1/4 y^4 - y^3 + y^2]_2^3 \\ = > 1/4 (81 - 27 + 9) - 1/4 (16 - 8 + 4) = 7/4My = 1/2 \int\limits^3_2 [(y-1)^2 - 3] dx \\\\= > 1/2 \int\limits^3_2 [(y-1)^2 - 3] (dy/dx) dx \\\\\)
\({using dx = (dy/dx) dy}\\ = 1/2 \int\limits^3_2 [(y-1)^2 - 3] (2(y-1)) dx \\ {using dy/dx = 2(y-1)} \\ = \int\limits^3_2 (y-1)^2 (y-2) dx \\ = \int\limits^2_1u^2 (u+1) du \\ {using[ u = y-1], and[ dx = (1/2(y-1)) dy]} \\ = [1/3 u^3 + 1/4 u^4]_1^2 \\ = 1/3 (8 + 4) - 1/3 (1 + 1) = 7/3X = Mx / A = (7/4) / (5/3) = 21/20Y = My / A = (7/3) / (5/3) + 1 = 10/3\)
Therefore , the center of mass of the region is (21/20, 10/3).

The first two steps in determining the solution set of the system of equations, y = x2 – 6x + 12 and y = 2x – 4, algebraically are shown in the table.
Which represents the solution(s) of this system of equations?
(4, 4)
(–4, –12)
(4, 4) and (–4, 12)
(–4, 4) and (4, 12)
Answer:
(4,4)
Step-by-step explanation:
The solution set of the system of equations can be found by setting the two equations equal to each other and solving for x.
x^2 - 6x + 12 = 2x - 4
x^2 - 8x + 16 = 0
(x - 4)^2 = 0
x = 4
Since both equations in the system are equal to y, we can substitute x = 4 into either equation to find the corresponding value of y.
y = 2x - 4 = 2(4) - 4 = 4
Therefore, the solution of this system of equations is (4, 4).
Therefore, the correct answer is (4, 4).

We have a repeating decimal 4.6(1).

4.6(1) = 4.6 + 0.01 + 0.001 + 0.0001 + ...Fund the sum of infinite GP, with the first term of a = 0.01 and common ratio of r = 0.1:
S = a/(1 - r) S = 0.01/(1 - 0.1) = 0.01/0.9 = 1/90Add 4.6 to the sum:
4.6 + 1/90 =4 + 0.6 + 1/90 =4 + 6/10 + 1/90 = 4 + 54/90 + 1/90 = 4 + 55/90 = 4 + 11/184 11/18Hence the fraction is 4 11/18.

The average of 5 consecutive even integers is 6. What is the least of these 5 integers?
Answer: 2
Step-by-step explanation:
5 consecutive integers with an average means the middle number will be the average since they are consecutive and even (increasing by 2/decreasing by 2). Because the middle number is 6, then the highest number will be 4 more and the lowest number will be 4 less. The consecutive numbers will be 2, 4, 6, 8, 10 and the lowest numbers is 2.
Answer:
4
Step-by-step explanation:
Consecutive numbers are numbers that increment by 1 (Ex. 1,2,3,4,5)
If the mean is 6, we know that the middle number has to be 6 and since these numbers are consecutive we can set 6 as "x" and write the following:
(x - 2, x - 1, x, x + 1, x + 2)
Plugging in 6 into the data set:
(4, 5, 6, 7, 8)

8–2|4–5y|=4 help me as quick as u can plzzz
Answer: \(y=\frac{2}{5}, \frac{6}{5}\)
Step-by-step explanation:
When answering a problem like this, you first isolate the absolute value. TO do this, first subtract 8 from both sides, to get –2|4–5y|=-4. Then divide both sides of the equation to get |4–5y|=2. The next thing you do is split the equation into 4-5y=2 and 4-5y=-2, because the contents of the absolute value could be negative or positive, and simplifying both into y = 2/5, and y = 6/5y.

1. how do we change a similar fraction?
2. how do we add the similar fraction?
Answer:
You add similar fraction by adding the numerators together but since the denominators are the same u keep them as they are
1. Similar fractions are those which have the same denominator. To change dissimilar fraction to similar fractions, you express them as a equivalent with a common denominator. For example 2/12, 3/12
2. To add similar fraction one should ensure that both the numerator are same and then add the numerator and put that on the denominator. If there is need to simply the fraction then you should first simplify the fraction.
For example:- 1/4+4/4= 5/4
Here as we see that bot number denominator are same so it's addition is done easily
The dimension of the row space of a 3 x 3 matrix A is 2. (a) What is the dimension of the column space of A? (b) What is the rank of A? (c) What is the nullity of A? (d) What is the dimension of the solution space of the homogeneous system Ax = 0?
a) the dimension of its column space is also 2. b) the rank of A is 2. c) the nullity of matrix A is 1. d) the dimension of the solution space of the homogeneous system \(A_x = 0\) is also 1.
(a) The dimension of the row space of a matrix is equal to the dimension of its column space. So, if the dimension of the row space of matrix A is 2, then the dimension of its column space is also 2.
(b) The rank of a matrix is defined as the maximum number of linearly independent rows or columns in the matrix. Since the dimension of the row space of matrix A is 2, the rank of A is also 2.
(c) The nullity of a matrix is defined as the dimension of the null space, which is the set of all solutions to the homogeneous equation Ax = 0. In this case, the matrix A is a 3 x 3 matrix, so the nullity can be calculated using the formula:
nullity = number of columns - rank
nullity = 3 - 2 = 1
Therefore, the nullity of matrix A is 1.
(d) The dimension of the solution space of the homogeneous system Ax = 0 is equal to the nullity of the matrix A. In this case, we have already determined that the nullity of matrix A is 1. Therefore, the dimension of the solution space of the homogeneous system \(A_x = 0\) is also 1.

An MIS differs from a TPS in that it creates databases.A. TrueB. False
An MIS differs from a TPS in that it creates databases is True.
An MIS (Management Information System) does indeed differ from a TPS (Transaction Processing System) in that it creates databases. The main purpose of an MIS is to collect, process, store, and disseminate information to support managerial decision-making within an organization. It involves the use of technology and various information systems to manage and analyze data for strategic planning, monitoring, and control.
One of the key components of an MIS is the creation and management of databases. Databases are structured collections of data that are organized, stored, and accessed in a systematic way. They serve as a central repository for storing relevant information that can be utilized by the MIS. These databases can contain data from various sources within the organization, such as sales records, customer information, inventory data, financial data, and more.
On the other hand, a TPS focuses primarily on the processing of transactions. It is designed to capture, process, and record day-to-day operational transactions, such as sales transactions, inventory updates, customer orders, and so on. While a TPS may store and retrieve data related to these transactions, its main focus is on efficiently processing and ensuring the accuracy and integrity of transactional data.
In summary, an MIS goes beyond the functionalities of a TPS by not only processing transactions but also creating and managing databases to support the informational needs of managers.
