Answer:
You need to order 11100 pizzas.
Explanation:
A couple of assumptions here.
Each pizza has 12 slices. Each guest will eat 4 slices (1/3 of a pizza).
83 * 1/3 = 28 pizzas
28 = 11100
A scared kangaroo clears a fence that is 2.44 meters tall. What is the vertical component of the kangaroos velocity at take off ? If the horizontal component of the kangaroos velocity is 4.80 m per s at what angle did the kangaroo take off the ground? (hint: at its maximum height the kangaroos vertical velocity is 0)
Answer:
a) The vertical component of the kangaroo's velocity at take off is approximately 4.982 meters per second.
b) The angle at which the kangaroo took off the ground is approximately 46.066º.
Explanation:
a) According to the statement, the kangaroo has an initial horizontal velocity and jumps to overcome the fence until velocity becomes zero. If effects from non-conservative forces can be neglected, then we represent the situation of the kangaroo by Principle of Energy Conservation:
[tex]K_{1}+U_{g,1} = K_{2}+U_{g,2}[/tex] (Eq. 1)
Where:
[tex]K_{1}[/tex], [tex]K_{2}[/tex] - Initial and final translational kinetic energies, measured in joules.
[tex]U_{g,1}[/tex], [tex]U_{g,2}[/tex] - Initial and final gravitational potential energies, measured in joules.
By definitions of translational kinetic and potential gravitational energies, we expand and simplify the equation above:
[tex]\frac{1}{2}\cdot m\cdot [(v_{1,x}^{2}+v_{1,y}^{2})-(v_{2,x}^{2}+v_{2,y}^{2})] = m\cdot g \cdot (y_{2}-y_{1})[/tex]
[tex]\frac{1}{2}\cdot [(v_{1,x}^{2}+v_{1,y}^{2})-(v_{2,x}^{2}+v_{2,y}^{2})] = g \cdot (y_{2}-y_{1})[/tex] (Eq. 2)
Where:
[tex]m[/tex] - Mass of the kangaroo, measured in kilograms.
[tex]g[/tex] - Gravitational acceleration, measured in meters per square second.
[tex]y_{1}[/tex], [tex]y_{2}[/tex] - Initial and final heights of the kangaroo above the ground, measured in meters.
[tex]v_{1,x}[/tex], [tex]v_{1,y}[/tex] - Vertical and horizontal initial velocities, measured in meters per second.
[tex]v_{2,x}[/tex], [tex]v_{2,y}[/tex] - Vertical and horizontal final velocities, measured in meters per second.
If we know that [tex]v_{1,x} = 4.80\,\frac{m}{s}[/tex], [tex]v_{2, x} = 0\,\frac{m}{s}[/tex], [tex]v_{2,y} = 0\,\frac{m}{s}[/tex], [tex]g = 9.807\,\frac{m}{s^{2}}[/tex] and [tex]y_{2}-y_{1} = 2.44\,m[/tex], then (Eq. 2) is reduced into this:
[tex]11.52+0.5\cdot v_{1,y}^{2}=23.929[/tex]
Lastly, we solve for [tex]v_{1,y}[/tex]:
[tex]0.5\cdot v_{1,y}^{2}=12.409[/tex]
[tex]v_{1,y}^{2} = 24.818[/tex]
[tex]v_{1,y} \approx 4.982\,\frac{m}{s}[/tex]
The vertical component of the kangaroo's velocity at take off is approximately 4.982 meters per second.
b) The angle at which the kangaroo took off the ground ([tex]\theta[/tex]), measured in sexagesimal degrees, is obtained by the following inverse trigonometric relation:
[tex]\theta =\tan^{-1}\left(\frac{v_{1,y}}{v_{1,x}} \right)[/tex] (Eq. 3)
[tex]\theta = \tan^{-1}\left(\frac{4.982\,\frac{m}{s} }{4.80\,\frac{m}{s} } \right)[/tex]
[tex]\theta \approx 46.066^{\circ}[/tex]
The angle at which the kangaroo took off the ground is approximately 46.066º.

Large ones are for more important thing. Such as gaming and special software.
Explanation:
Hope that helps
Large systems are the ones that are for more important thing. Such as gaming and special software.
Why is the size of a computer Important?Computer scientists and users value the classification of computers based on their size. It enables us to classify the computer system according to its size and processing capacity.
For gamers who desire the greatest possible gaming experience, expensive PCs are also wonderful.
You can play the most recent games smoothly and at high settings if you have a powerful computer. A costly PC also has the benefit of lasting longer than a less expensive model.
Most computer monitors have a diagonal measurement from corner to corner that falls between 19 and 34 inches. 22 to 24" screens will be sufficient for the majority of users.

Which class members should be declared as public?
a
Data attributes and constructor methods
b
Data attributes only
c
Methods and occasionally final attributes
d
Predominantly data attributes and some helper methods
Answer:
B. Methods and occasionally final attributes
Explanation:
In Computer programming, class members can be defined as the members of a class that typically represents or indicates the behavior and data contained in a class.
Basically, the members of a class are declared in a class, as well as all classes in its inheritance hierarchy except for destructors and constructors.
In a class, member variables are mainly known as its attributes while its member function are seldomly referred to as its methods or behaviors.
One of the main benefits and importance of using classes is that classes helps to protect and safely guard their member variables and methods by controlling access from other objects.
Therefore, the class members which should be declared as public are methods and occasionally final attributes because a public access modifier can be accessed from anywhere such as within the current or external assembly, as there are no restrictions on its access.

A(n) ___________ analyzes traffic patterns and compares them to known patterns of malicious behavior.a. Intrusion prevention system b. intrusion detection system c. defense-in-depth strategy d. quantitative risk assessment
Answer:b. intrusion detection system
Explanation:
An intrusion detection system (IDS) helps to alert service administrators to detect suspicious or malicious activity by monitoring and analyzing specific patterns to network traffic. Most times, the IDS may be configured to respond to suspicious malicious traffic by blocking the cyber attacker making such IP address unable to access that particular network.
An intrusion detection system (IDS) can be either a Host Based Intrusion Detection Systems (HIDS) or a Network Based Intrusion Detection Systems (NIDS) depending on preference by the user.
It is therefore necessary for businesses who require high level of security to adopt good and effective intrusion detection systems so that the communication of information from businesses to businesses can be safeguarded and secure from cyber attacks.
a) Explain 3 phase Alternative Current with aid of diagram.
Three-phase electric power is a common method of alternating current electric power generation, transmission, and distribution. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. It is also used to power large motors and other heavy loads.
A three-wire three-phase circuit is usually more economical than an equivalent two-wire single-phase circuit at the same line to ground voltage because it uses less conductor material to transmit a given amount of electrical power. Polyphase power systems were independently invented by Galileo Ferraris, Mikhail Dolivo-Dobrovolsky, Jonas Wenström, John Hopkinson and Nikola Tesla in the late 1880s.

Write a function named power that accepts two parameters containing integer values (x and n, in that order) and recursively calculates and returns the value of x to the nth power.
Answer:
Following are the code to the given question:
int power(int x, int n)//defining a method power that accepts two integer parameters
{
if (n == 0)//defining if block to check n equal to 0
{
return 1; //return value 1
}
else//defining else block
{
x = x * power(x, --n); //use x variable to call method recursively
}
return x; //return x value
}
Explanation:
In the above-given code, a method power is defined that accepts two integer variable in its parameter, in the method a conditional statement is used which can be defined as follows:
In the if block, it checks "n" value, which is equal to 0. if the condition is true it will return value 1.In the else block, an integer variable x is defined that calls the method recursively and return x value.4. When the keyword ____________________ is followed by a parenthesis, it indicates a call to the superclass constructor.
Answer:
Super
Explanation:
In object-oriented programming (OOP) language, an object class represents the superclass of every other classes when using a programming language such as Java. The superclass is more or less like a general class in an inheritance hierarchy. Thus, a subclass can inherit the variables or methods of the superclass.
Basically, all instance variables that have been used or declared in any superclass would be present in its subclass object.
Hence, when the keyword super is followed by a parenthesis, it indicates a call to the superclass constructor and it should be the first statement declared in the subclass constructor.
Describe an algorithm that takes as input a list of n integers in nondecreasing order and produces the list of all values that occur more than once. (
Answer:
Input a series of integer numbers and split the string from the input to get a list. Then check and convert each string to integer with a list comprehension. Create a new variable with a value equal to the set of the list ( to get unique values) then check for the occurrence of each value in the original list.
Explanation:
This algorithm is used to check for the occurrence of values in a list that has been sorted in ascending order. This is faster if the items in the list is not converted to integer yet (still strings) before writing a for loop to check the value count in the list.
