Answer:
The answer to this question can be defined as follows:
Explanation:
Given value:
[tex]x = t^2 + 5......(1)\\\\ y = t^2 + 5t........(2)[/tex]
To find:
[tex]\bold {\frac{dy}{dx} \ \ \ and\ \ \ \frac{d^2y}{dx^2} = ?}[/tex]
Differentiate the above equation:
equation 1:
[tex]\frac{dx}{dt}= 2t.......(1)\\[/tex]
equation 2:
[tex]\frac{dy}{dt}= 2t+5[/tex]
Formula:
[tex]\frac{dy}{dx}= \frac{\frac{dy}{dt}}{\frac{dx}{dt}}\\\\[/tex]
[tex]\boxed{\bold{\frac{dy}{dx}=\frac{2t+5}{2t}}}[/tex]
To calculate the [tex]\bold{\frac{d^2y}{dx^2}}[/tex] we Differentiate the above equation but before that first solve the equation:
Equation:
[tex]\frac{dy}{dx}=\frac{2t+5}{2t}[/tex]
[tex]=\frac{2t}{2t}+\frac{5}{2t}\\\\= 1+\frac{5}{2t}\\\\=1+\frac{5}{2} t^{-1} \\[/tex]
Formula:
[tex]\bold{\frac{d}{dx} \ x^n = nx^{n-1}}[/tex]
[tex]\frac{dy^2}{dx^2}= 0+\frac{5}{2} (-1 t^{-2})\\\\[/tex]
[tex]= -\frac{5}{2} t^{-2}\\\\= -\frac{5}{2 t^2} \\\\[/tex]
[tex]\boxed{\bold{\frac{d^2y}{dx^2}=-\frac{5}{2t^2}}}[/tex]

Explanation:
Write a method, getFirstLine, that is passed a String argument and that returns the first line. (Recall that lines are terminated with the "\n" character.) Assume that the argument contains at least one complete, newline-terminated line.
My Solution:
public String getFirstLine(String a)
{
String[] myLines = a.split("\n");
return(myLines[0]);
}
Answer: The answer to this question can be given as:
Method definition :
String getSecondLine (String aString) //define function getSecondLine()
{
return aString.substring(aString.indexOf("\n") + 1, aString.indexOf("\n") + 1 + aString.substring(aString.indexOf("\n") + 1, aString.length()).indexOf("\n"));
//return value.

A binary search function is searching for a value that is stored in the middle element of an array. How many times will the function read an element in the array before finding the value?
Answer: 1 time.
Explanation:
A binary function is also known as a half-interval search is a search algorithm to find the position of a given element x within a well-sorted array []. Binary search compares the target value to the middle element of the array.It ignores half of the elements just after one comparison. it compares x with the middle element.So, the function read an element one time in the array before finding the value.

In the classified section of a local newspaper, I came across job openings for the post of a network engineer in two different companies. One was from the airline industry, while the other was from the food and beverage industry.
The airline company required an applicant to have a bachelor's degree in network administration. The job posting specified that applicants with supporting CCENT or CompTIA Security+ certifications would be preferred. The company was willing to consider candidates with no prior experience. The job responsibilities included: maintaining security, DNS, IP routing, firewalls, and troubleshooting IT-related problems. The role also required skills to manage multi-site network operations, operating systems, and other software applications in public as well as private facilities. Another responsibility was to complete the time logs in the company's records to facilitate timely and accurate billing.
For the role of a network engineer in the food and beverage industry, the required qualification was any bachelor's degree in computer science with a minimum of one year of relevant experience. Certifications were an added advantage, but they were not a necessity. The job role required skills to troubleshoot network glitches, monitor network usage, install software and hardware infrastructure, provide technical assistance to users, and suggest improvements in the system.
Explanation:
A college marketing department has a networked storage device that uses the IP address 10.18.7.5, TCP port 443 for encryption, and UDP port 4365 for video streaming. The college already uses PAT on the router that connects to the Internet. The router interface has the public IP address of 209.165.200.225/30. The IP NAT pool currently uses the IP addresses ranging from 209.165.200.228-236. Which configuration would the network administrator add to allow this device to be accessed by the marketing personnel from home
Answer:
The answer to this question can be defined as follows:
Explanation:
The static NAT stands for (static Network Address Translation), which enables the user to modify a single interpretation for a local second-order to the external environment addresses, and all IP and port numbers were also transcribed inside to random traffic as well as from outside with the internal traffic.
It is used to map network traffic by an internal IP address from a static external IP address. It provides a fixed conversion for actual addresses onto maps. It offers Internet access to the network equipment via a private LAN with such a private IP address which is not recorded.Please find the attachment of the ip address.Which of the following statements is true?

Employees often have more than one laptop-so one or both of them are always handheld. For this cause, companies turn to the versatility and scalability of wireless networks. It is convenient to grant workers connectivity through a wireless network, which they can use to connect several devices. Tablets, smartphones and laptops can all be connected to the network, which enables employees to access
Answer: D. The actual speed of a network can differ from the maximum advertised speeds

How do I make my kali Linux faster in my virtual box?
Answer:
If you run any operating system as a VM, it is going to be slower than if you were to run it as a native OS. You can, however, make a VM run faster by allocating more CPU cores and RAM to it in your hypervisor's (such as Virtualbox or VMWare) settings menu for your VM.
does that make sense?
What VM are you using? if your using virual box then try adding more RAM to it. I use VMware player 16 and its REALLY fast so try that. Also, go on online and look up this guy called network chuck.
Which of the following statements is false? a. The Java API consists of packages. b. The Java API helps programmers avoid "reinventing the wheel." c. The Java API consists of import declarations. d. None of the above.
Answer:
The answer is "Option c".
Explanation:
In Java programming, the API stands for "application programming interface", which is also known as the lists of all classes in the JDK. It contains all packages, classes, and interfaces, with their techniques, fields. It is a built-in class, which gives the programmer a great deal of usability, and correct choices can be described as follows:
In option a, It is correct because it imports the package to use API. In option b, It allows you to "re-invent the wheel" by developers, that's why it is correct.Other than hard discs and flash discs, identify other three different storage media

GuardIN is an IT security firm. It deals with highly secure data for a wide variety of software and e-commerce agreements, trademark licenses, and patent licenses. GuardIN needs a cloud computing option that would allow it to purchase and maintain the software and infrastructure itself. The cloud also needs to be designed in such a way that all users of the organization can access it without any lag. Which of the following cloud computing options would be most suitable for GuardIN?
A) A public cloud
B) A community cloud
C) A hybrid cloud
D) A private cloud
Answer:
D) A private cloud
Explanation:
Note we are told that GuardIN needs a cloud computing option that would allow it to purchase and maintain the software and infrastructure itself.
Thus, to be able to manage the cloud infrastructure itself; it implies buying it's own hardware equipments, which means it is best to use a private cloud computing option.
Doing so would give GuardIN the opportunity to design the cloud storage in a way that all users of the organization can access it without any lag.
