Karolina [17]

Answer:

d. involves analyzing end-user business requirements in order to refine project goals

Explanation:

In the software development life cycle, the implementation stage is the stage where the computer programmers begin the actual coding of the application required by the end-user. At this stage, the developer takes into account the needs and specifications of the customer.

For example, if the end-user wants a software application that can track payment records, the researcher at this stage begins using the right software to code programs that can effect this function.

Define a function compute_gas_volume that returns the volume of a gas given parameters pressure, temperature, and moles. Use

jeyben [28]

Question:

Define a function compute_gas_volume that returns the volume of a gas given parameters pressure, temperature, and moles. Use the gas equation PV = nRT, where P is pressure in Pascals, V is volume in cubic meters, n is number of moles, R is the gas constant 8.3144621 ( J / (mol*K)), and T is temperature in Kelvin.

Answer:

This solution is implemented in C++

double compute_gas_volume(double P, double T, double n){

double V = 8.3144621 * n * T/P;

return V;

}

Explanation:

This line defines the function, along with three parameters

double compute_gas_volume(double P, double T, double n){

This calculates the volume

double V = 8.3144621 * n * T/P;

This returns the calculated volume

return V;

}

To call the function from the main, use:

cout<<compute_gas_volume(P,T,n);

Where P, T and n are double variables and they must have been initialized

Given that k refers to a non-negative int value and that t has been defined and refers to a tuple with at least k+1 elements, wr

Rus_ich [418]

Answer:

The expression is "t[k]".

Explanation:

In the question, it is defined that variable k refers to positive integer and variable t refers to a tuple that holds at least k+1 element. The expression for defining the kth element of t is t[k].

Where variable t is tuple that collects a sequence of immutable (in-built) Python objects. To define tuple we use the parentheses.

The main purpose to use tuple in this question is that it cannot be changed.

Answer:

A binary system is a system that functions on zeros and ones (0's and 1's).

A decimal system is an Arabic numeric system that has 10 as its base and uses a dot which is also called a decimal point to show fractions.

Differences

A decimal uses ten different digits which is 0-9 while a binary system uses just two digits 0 and 1
Decimal system was historically a Hindu-Arabic system while the binary system is just an Arabic system

Similarities

They are capable of performing arithmetic operations
They both can be represented in decimal form
