The preferred means of creating multithreaded Java applications is by implementing the ________ interface. An object of a class that implements this interface represents a task to perform.
Answer:
Runnable.
Explanation:
Java is an all round programming language which is typically object-oriented and class-based. It was designed by James Gosling, developed by Sun microsystems and released officially on the 23rd of May, 1995. Java programming language is designed to have only a few implementation dependencies as possible because it was intended to be written once, and run on any platform.
Java makes concurrency to be available to software developers through the application programming interface (API) and the language. Also, it supports multiple threads of execution, by making each thread have its respective program counter and method-call stack, which then allow concurrent executions with other threads.
The preferred means of creating multithreaded Java applications is by implementing the runnable interface. An object of a class that implements this interface represents a task to perform. The code is public void run ().

The barometric height in a town is 65cmHg. Given that the standard atmospheric pressure
is 76cmHg and density of mercury is 13600kg/m", determine the altitude of the town. (Density of
(3mks)
air is 1.25kg/mº).
Answer:
Altitude of the town(h1) = 1,196.8 m
Explanation:
Given:
Height of barometer(h) = 65 cm Hg = 0.65
Standard atmospheric pressure = 76 cm Hg = 0.76
Density of mercury(Pm) = 13,600 kg/m³
Density of air (Pa) = 1.25 kg/m³
Find:
Altitude of the town(h1)
Computation:
Pressure due column = Δp mercury column
(Pa)(h1) = (Pm)(h)
(1.25)(h1) = (13,600)(0.76-0.65)
(1.25)(h1) = 1,496
Altitude of the town(h1) = 1,196.8 m

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.

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.What process is used to convert numbers between the binary system and the decimal system? (A.)Enter the number in a calculator, divide by 2, and multiply by 10.,(B)Convert each binary number to a letter, then use the letter’s place in the alphabet as the decimal representation ( e.g., A = 1, B = 2),(C.)Add up the digits in the binary number and place the sum behind a decimal point,(D.)Look up the number on a binary-to-decimal conversion table.
Answer:
(D.)Look up the number on a binary-to-decimal conversion table.
Explanation:
Though there are other ways of converting binary-to-decimal but from the given list of options, the best option that describes this conversion is option D.
Analyzing each of the options;
Option A
A binary number can't be converted to decimal by merely dividing it by 2 and multiplying the result by 10;
Take for instance; 11 in binary;
Divide by 2
11/2 = 5.5
Multiply result by 10
5.5 * 10 = 55
This final outcome is incorrect; as 11 in binary = 3 in decimal
Option B
This is also incorrect because as there is no room for alphabets in binary representation of numbers
Option C
This will also give an incorrect result;
Take for instance 11
Add up the digits
1 + 1 = 2
Place a decimal point behind;
This gives 2. or 2.0
This final outcome is incorrect; as 11 in binary = 3 in decimal
Option D
Looking up the number on a conversion table gives the accurate result
There are different types of conversion process. The process used to convert numbers between the binary system and the decimal system is to Look up the number on a binary-to-decimal conversion table.
Binary to decimal conversion is often done to show a number that is listed out in binary number system to its equivalent usually in decimal number system.
For easy conversion, one can Divide the binary number by 2 and write out the remainder. Thereafter you can divide by 2 again and write remainder and this process continue till the last remainder becomes 1 .
After that write all the remainders in the (0 , 1) order. With this, the decimal is converted into binary.

Is a collection of data or computer instructions that tell the computer how to work.
Explanation:
Referential integrity states that:______.
A. Something assigned to an attribute when no other value applies (N/A) or when the applicable value is unknown;
B. Values of an attribute must be taken from a pre-defined domain;
C. No primary key attribute (or component of a primary key) can be null;
D. Each foreign key value MUST match a primary key value in another relation or the foreign key value must be null;
Answer:
D. Each foreign key value MUST match a primary key value in another relation or the foreign key value must be null.
Explanation:
In Computer programming, integrity constraints can be defined as a set of standard rules that ensures quality information and database are maintained.
Basically, there are four (4) types of integrity constraints and these are;
1. Key constraints.
2. Domain constraints.
3. Entity integrity constraints.
4. Referential integrity constraints.
Referential integrity states that each foreign key value must match a primary key value in another relation or the foreign key value must be null.
For instance, when a foreign key in Table A points to the primary key of Table B, according to the referential integrity constraints, all the value of the foreign key in Table A must be null or match the primary key in Table B.
Hence, the referential Integrity constraints ensures that the relationship between the data in a table is consistent and valid.
Consider a Rational class designed to represent rational numbers as a pair of int's, along with methods reduce (to reduce the rational to simplest form), gcd (to find the greatest common divisor of two int's), as well as methods for addition, subtraction, multiplication, and division. Why should the reduce and gcd methods be declared to be private.
Answer:
There is not a reason for the two methods to be private unless you want to only allow objects of the class Rational to have access to these methods. Perhaps your professor has a particular reason for requiring it to be set up as such.
Explanation:
The use of the private space simply restricts access to either variables or methods contained within the space to the class object that is associated with the variable or methods.
The use of the public space allows the method or variable to be accessed from anywhere within the program.
Note, if using class inheritance, classes that inherit from the Rational class will not be able to access the private functions.

Find dy/dx and d2y/dx2. x = t2 + 5, y = t2 + 5t dy dx = Correct: Your answer is correct. d2y dx2 = Correct: Your answer is correct. For which values of t is the curve concave upward? (Enter your answer using interval notation.) Changed: Your submitted answer was incorrect. Your current answer has not been submitted.
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]
