Answers
The expressions are:
(r-s)(x) = x + 3
(r+s)(x) = 7x - 3
And the value of (r∘s)(3) is unknown without the expression for r(x).
To find the expressions for (r-s)(x) and (r+s)(x) and evaluate (r∘s)(3), where f(x) = 4x and g(x) = 3x - 3, we can substitute these functions into the given expressions.
1. (r-s)(x):
The expression for (r-s)(x) is obtained by subtracting g(x) from f(x):
(r-s)(x) = f(x) - g(x) = (4x) - (3x - 3) = 4x - 3x + 3 = x + 3
2. (r+s)(x):
The expression for (r+s)(x) is obtained by adding f(x) and g(x):
(r+s)(x) = f(x) + g(x) = (4x) + (3x - 3) = 4x + 3x - 3 = 7x - 3
3. Evaluating (r∘s)(3):
(r∘s)(3) means substituting x = 3 into the function composition (r∘s)(x). First, we evaluate s(3):
s(3) = 3(3) - 3 = 9 - 3 = 6
Then, we substitute s(3) into r(x):
(r∘s)(3) = r(s(3)) = r(6)
Since we don't have the expression for r(x), we cannot determine the specific value of r(6) or simplify it further without additional information.
Therefore, the expressions are:
(r-s)(x) = x + 3
(r+s)(x) = 7x - 3
And the value of (r∘s)(3) is unknown without the expression for r(x).

(a) (i) What conditions should be satisfied to use image averaging method for noise reduction? (ii) Using mathematical expressions, characterize the noise in the resultant image when K images are averaged, as K becomes large. (iii) Would you select spatial averaging or temporal image averaging when either method can be used for noise reduction? Explain your selection in detail.
Answers
(a)image averaging is a very effective method of reducing noise in images. Image averaging reduces noise by adding multiple images of the same scene together and then dividing by the number of images added.The conditions that must be fulfilled for the image averaging method are as follows:-
(i) The background of the image must not move between each image capture.- The noise present in the image must be random.- The source of the noise must be consistent.
(ii)The mathematical expression that characterizes the noise in the resultant image when K images are averaged, as K becomes large is given by;sigma_n^2/K
Where;sigma_n^2 is the variance of the noise and K is the number of images that have been averaged.
Therefore, as K increases, the variance of the noise in the resultant image reduces, and thus, the noise reduces.When either method can be used for noise reduction, the temporal image averaging method would be the preferred method to select.
(iii)This is because it uses a sequence of images that are taken at different times, usually at high speeds, to produce a single image that is free of noise. This method is best when dealing with fast-moving objects, and it can be used in situations where the camera cannot be stabilized and is experiencing unwanted vibration or shaking.

League of United Latin American Citizens v. Perry and Shaw v. Reno are two prominent US Supreme Court cases with key differences.
League of United Latin American Citizens v. Perry (2006)This case was in response to a 2003 redistricting of Texas legislative districts. The state's congressional and state representative districts were redrawn by the Republican-controlled legislature to favor their party.Shaw v. Reno (1993)The case was in response to the creation of a district in North Carolina that was predominantly Black. This case challenged the constitutionality of the district's odd shape, which critics claimed was created solely to give Black voters an advantage.

Critical Thinking You need to know the number of different arrangements possible for five distinct letters. You decide to use the permutations rule, but your friend tells you to use 5!. Who is correct? Explain.
Answers
Friend is incorrect and the permutations rule should be used instead of just 5!.
Permutations are a process in which the order of items in a set matters. In other words, it refers to the different arrangements that can be made by selecting r items from n different objects, without repeating any of them.
Calculating permutations manually can be time-consuming.
However, the permutations rule simplifies the process.
The permutations rule states that the number of permutations of n distinct objects, taken r at a time, is equal to
nPr = n!/(n-r)!,
where "n" represents the total number of distinct objects and
"r" represents the number of items selected for each arrangement.
So, if you want to find the number of arrangements possible for five distinct letters, you need to use the permutation rule and not just 5!.
This is because 5! represents the number of ways to arrange five distinct objects (letters) in a line, without restrictions, meaning that the same letter can appear twice, or more, in the arrangement.
However, if the five distinct letters are taken two, three, four, or five at a time, then the permutations rule would have to be used.
For example, the number of different arrangements of two letters out of five distinct letters is equal to
5P2 = 5!/3!
= 5 × 4
= 20.
Therefore, your friend is incorrect and the permutations rule should be used instead of just 5!.
