Answer:

The earliest age of technology. It can be defined as the time between 3000 B.C. and 1450 A.D. When humans first started communicating, they would try to use language to make simple pictures – petroglyphs to tell a story, map their terrain, or keep accounts such as how many animals one owned, etc.

Write a statement that reads 5 successive integers into these variables that have already been declared: x1, x2, x3, x4, x5. The

prisoha [69]

Answer:

Following are the statement in C++ language :

#include <iomanip> // header file

using namespace std; // namespace

int main() // main method

{

int x1,x2,x3,x4,x5; // variable declaration

cout<<" Enter the 5 sucessive integer:";

cin>>x1>>x2>>x3>>x4>> x5; // taking 5 input from user

cout<<right;

// prints each of its own line and form a right-justified

cout<<setw(5)<< x1 << "\n" << setw(5) << x2 << "\n" <<setw(5) << x3 << "\n" << setw(5) << x4 << "\n" << setw(5) << x5 << "\n";

return(0);

}

Output:

Enter the 5 sucessive integer: 45

445

Explanation:

Description of program is given below

Declared a 5 integer value x1,x2,x3,x4,x5 respectively.

Read the 5 integer value from user by using cin funtion.

Finally Print these 5 value in its own line and form a right-justified by using setw() function on it

Which type of app is the best choice when it is critical to be able to use the device's features but performance is not critical

lisov135 [29]

Answer:

Hybrid.

Explanation:

A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer on how to perform a specific task and solve a particular problem.

A software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications. There are seven (7) main stages in the creation of a software and these are; planning, analysis, design, development (coding), testing, implementation and execution, and maintenance.

Some of the models used in the software development life cycle (SDLC) are;

I. A waterfall model: it can be defined as a process which involves sequentially breaking the software development into linear phases. Thus, the development phase takes a downward flow like a waterfall and as such each phase must be completed before starting another without any overlap in the process.

II. An incremental model: it refers to the process in which the requirements or criteria of the software development is divided into many standalone modules until the program is completed.

III. A spiral model: it can be defined as an evolutionary SDLC that is risk-driven in nature and typically comprises of both an iterative and a waterfall model. Spiral model of SDLC consist of these phases; planning, risk analysis, engineering and evaluation.

Basically, softwares are categorized into three (3) main categories based on the development platform and these are;

a. Web application.

b. Native application.

c. Hybrid application.

A hybrid application is a type of software application that is designed based on the combination of the elements of both web applications and native applications.

Typically, a hybrid application is a web application that is developed in a native application shell, using a standardized web programming language such as CSS, JavaScript, and HTML.

Generally, a hybrid application avails a programmer the opportunity to write a code for a mobile application once while accommodating or being compatible with multiple app platforms such as Android, Windows, iOS, etc.

Hence, a hybrid application is the best choice of an application when it's critical for the end users to be able to use the features associated with a device such as a mobile phone but performance isn't critical.

I need help with completing this python code.Complete the Car class by creating an attribute purchase_price (type int) and the m

netineya [11]

Answer:

class Car:

def __init__(self):

self.model_year = 0

# TODO: Declare purchase_price attribute

self.purchase_price = 0

self.current_value = 0

def calc_current_value(self, current_year):

depreciation_rate = 0.15

# Car depreciation formula

car_age = current_year - self.model_year

self.current_value = round(self.purchase_price * (1 - depreciation_rate) ** car_age)

# TODO: Define print_info() method to output model_year, purchase_price, and current_value

def print_info(self):

print("Model year: ",self.model_year)

print("Purchase year: ",self.purchase_price)

print("Current value: ",self.current_value)

def main():

year = int(input())

price = int(input())

current_year = int(input())

my_car = Car()

my_car.model_year = year

my_car.purchase_price = price

my_car.calc_current_value(current_year)

my_car.print_info()

if __name__ == "__main__":

main()

Explanation:

The Car class in the python program is used to create a car object instance with class methods model_year, purchase_price, and calc_current_value, which accepts as arguments, year, price and current_year respectively. The main function runs if only the python module is run and interpreted to print out the year and current price of a car object instance defined.
