Explanation:
Given that,
The maximum range of a projectile is x.
Maximum range occurs when the angle of projection is 45°. Using formula for maximum range.
[tex]R=\dfrac{v^2}{g}[/tex]
According to the question,
[tex]x=\dfrac{v^2}{g}[/tex] ...(1)
Maximum height,
[tex]h=\dfrac{v^2}{2g}[/tex]
From equation (1).
[tex]h=\dfrac{x}{2}[/tex]
Hence, this is the required solution.

The computer scientists Richard Conway and David Gries once wrote: The absence of error messages during translation of a computer program is only a necessary and not a sufficient condition for reasonable [program] correctness. Rewrite this statement without using the words necessary or sufficient.
Answer:
A computer program is not reasonably correct if it has no error messages during translation.
Explanation:
First, we need to understand what the statement means, and we also need to identify the keywords.
The statement means that, when a program does not show up error during translation; this does not mean that the program is correct
Having said that:
We can replace some keywords as follows:
absence of error messages := no error messages
You are given an array of arrays a. Your task is to group the arrays a[i] by their mean values, so that arrays with equal mean values are in the same group, and arrays with different mean values are in different groups. Each group should contain a set of indices (i, j, etc), such that the corresponding arrays (a[i], a[j], etc) all have the same mean. Return the set of groups as an array of arrays, where the indices within each group are sorted in ascending order, and the groups are sorted in ascending order of their minimum element.
Example
For
a = [[3, 3, 4, 2],
[4, 4],
[4, 0, 3, 3],
[2, 3],
[3, 3, 3]]
the output should be
meanGroups(a) = [[0, 4],
[1],
[2, 3]]
mean(a[0]) = (3 + 3 + 4 + 2) / 4 = 3;
mean(a[1]) = (4 + 4) / 2 = 4;
mean(a[2]) = (4 + 0 + 3 + 3) / 4 = 2.5;
mean(a[3]) = (2 + 3) / 2 = 2.5;
mean(a[4]) = (3 + 3 + 3) / 3 = 3.
There are three groups of means: those with mean 2.5, 3, and 4. And they form the following groups:
Arrays with indices 0and 4 form a group with mean 3;
Array with index 1 forms a group with mean 4;
Arrays with indices 2and 3 form a group with mean 2.5.
Note that neither
meanGroups(a) = [[0, 4],
[2, 3],
[1]]
nor
meanGroups(a) = [[0, 4],
[1],
[3, 2]]
will be considered as a correct answer:
In the first case, the minimal element in the array at index 2 is 1, and it is less then the minimal element in the array at index 1, which is 2.
In the second case, the array at index 2 is not sorted in ascending order.
For
a = [[-5, 2, 3],
[0, 0],
[0],
[-100, 100]]
the output should be
meanGroups(a) = [[0, 1, 2, 3]]
The mean values of all of the arrays are 0, so all of them are in the same group.
Input/Output
Answer:
import numpy as np
a = [[3, 3, 4, 2], [4, 4], [4, 0, 3, 3], [2, 3], [3, 3, 3]]
mean_holder = [np.array(i).mean() for i in a]
mean_groups= [[i for i,x in enumerate(mean_holder) if x==v] for v in mean_holder]
mean_g = []
for i in mean_groups:
if i not in mean_g:
mean_g.append(i)
print(mean_holder)
print(mean_g)
Explanation:
The python's Numpy package is used to convert the lists in the a-list into arrays and the means are taken and grouped by index

Assume a future where security counter measures against DoS attacks are much more widely implemented than at present. In this future network, anti-spoofing and directed broadcast filters are widely deployed. Also, the security of PCs and workstations is much greater, making the creation of botnets difficult. Do the administrators of server systems still have to be concerned about, and take further countermeasures against, DoS attacks? If so, what types of attacks can still occur, and what measures can be taken to reduce their impact? Explain in detail with valid diagram and example.
Answer:
yes administrators have to be concerned
Explanation:
It is necessary for countermeasures to be taken against DoS attacks
The types of attacks that can still occur are:
If the network connection get to be overloaded, there could be flash crown of this computer system and fraudulent activities maybe initiated. By flash crowd we mean that the there is a great deal of traffic on the system and this could cause the network connection to be destroyed.
To reduce the impact of this kind of attacks,
1. there should be enough or excess network bandwidth and distributed servers should be replicated if there is a possibility that network could get to be overloaded.
2. restriction is more commonly done on sporting sites. Restriction brings about an increase in implementation cost.
3. The impact of this type of attack can be reduced by stopping unwanted traffic throught the implementation of filters
4. Use strong antivirus on computer sytems that are used to connect to the internet

A video game character can face toward one of four directions: north, south, east, and west. Each direction is stored in memory as a sequence of four bits. A new version of the game is created in which the character can face toward one of eight directions, adding northwest, northeast, southwest, and southeast to the original four possibilities. Which of the following statements is true about how the eight directions must be stored in memory?
A. Four bits are not enough to store the eight directions. Five bits are needed for the new version of the game.
B. Four bits are enough to store the eight directions
C. Four bits are not enough to store the eight directions. Sodeen bits are needed for the new version of the game.
D. Four bits are not enough to store the eight directions. Eight bits are needed for the new version of the game.
Answer:
B. Four bits are enough to store the eight directions
Explanation:
The summary of the question is to determine whether 4 bits can store 8 directions or not.
To understand this question properly, the 8 bits will be seen as 8 different characters.
In computer memory, a computer of n bits can store 2^n characters.
In this case:
[tex]n = 4[/tex] i.e. 4 bits
So:
[tex]2^n = 2^4[/tex]
[tex]2^n = 16[/tex]
This implies that the memory can store up to 16 characters.
Because 16 > 8, then (b) answers the question.
Your co-worker who went to UCLA tells you that DHCP is not enabled at your new job, so you should just use the same IP address that you have at home to connect to the internet. He told you it should work because your computer is communicating with a unique public IP address at home, so no other computer in the world would have it. When you try this, your computer does not have internet access. Give two reasons why?
Answer:
1. internet connection is not enabled on the computer.
2. The DHCP server in the company is not enabled as well.
Explanation:
For a user to access the internet, the computer must have a public IP address that is either assigned to it by a service provider or dynamically from the DHCP server in the computer. In the case of the former, the user just needs to enable the internet connection to obtain the unique IP address.
If the DHCP server or the internet connection is not enabled, the user would not have access to the internet.

Write a program that would determine the day number in a non-leap year. For example, in a non-leap year, the day number for Dec 31 is 365; for Jan 1 is 1, and for February 1 is 32. This program will ask the user to input day and month values. Then it will display the day number day number corresponding to the day and month values entered assuming a non-leap year. (See part II to this exercise below).
Answer:
In Python:
months = ["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"]
daymonths = [31,28,31,30,31,30,31,31,30,31,30,31]
day = int(input("Day: "))
month = input("Month: ")
ind = months.index(month)
numday = 0
for i in range(ind):
numday+=daymonths[i]
numday+=day
print(numday)
Explanation:
This initializes the months to a list
months = ["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"]
This initializes the corresponding days of each month to a list
daymonths = [31,28,31,30,31,30,31,31,30,31,30,31]
This gets the day from the user
day = int(input("Day: "))
This gets the month from the user
month = input("Month: ")
This gets the index of the month entered by the user
ind = months.index(month)
This initializes the sum of days to 0
numday = 0
This adds up the days of the months before the month entered by the user
for i in range(ind):
numday+=daymonths[i]
This adds the day number to the sum of the months
numday+=day
This prints the required number of days
print(numday)

Thus, they can have a maximum of 256 colors, which is the amount of colors that 8 bits of information can specify (28 = 256). Fewer colors are produced by lower bit depths, which also result in smaller files. At the conclusion of this chapter, in Section 19.8, this is covered.
"Indexed color" refers to the fact that a color table contains the palette—the collection of colors—of the image. A reference (or "index") to a table cell containing the pixel's color is present in each pixel of the image.
By choosing Image Mode Color Table in Photoshop, you can view the table for an indexed color image.
