While you’re using the DELETE or UPDATE to change the data in any database like MySQL or ORACLE, the WHERE clause can be used to avoid inadvertently changing data everywhere.
<u>Explanation:</u>
The WHERE clause checks the condition and the changes mentioned by the DELETE or UPDATE command will be done if the condition is true. There are also other clauses like HAVING, IN which will have range either inclusive or exclusive.
It is also noted that in MySQL, there is a method called WorkBench which enables safe mode and doesn’t execute statements without the WHERE clause.
Assuming that this company sells all that it produces, the profit function would be given by P(x) = -0.5(x - 100)² + 5,000 - 50x - 100.
<h3>What is profit?</h3>
In Economics, profit can be defined as a measure of the amount of money (revenue) that is generated when the selling price is deducted from the cost price of a good or service, which is usually provided by producers.
This ultimately implies that, all producers generally work to maximize their profits and make them as large as possible, in order to enable them break even and successful.
Mathematically, the profit function P(x) of a business firm simply refers to the revenue function R(x) minus the cost function C(x):
P(x) = R(x) - C(x)
Where:
- R(x) represents how much it takes in.
- C(x) represents how much it spends.
Substituting the given parameters into the formula, we have;
P(x) = -0.5(x - 100)² + 5,000 - (50x + 100)
P(x) = -0.5(x - 100)² + 5,000 - 50x - 100

The 3-act structure<span> is an old principle widely adhered to in storytelling today. It can be found in plays, poetry, novels, comic books, short stories, video games, and the movies. It was present in the novels of Conan Doyle, the plays of Shakespeare, the fables of Aesop, the poetry of Aristotle, and the films of Hitchcock. It’s older than Greek dramaturgy. Hollywood and Broadway use it well. It’s irrefutable and bullet-proof, so to speak.
so this means its more basic antagonist protagonist set-up even if the protagonist and antagonist are "CUBES"</span>
Answer:
// here is code in the C++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main() {
// variable to store the input
int birth_month,birth_year;
cout<<"enter birth month:";
// read the birth month
cin>>birth_month;
cout<<"enter birth year:";
// read the birth year
cin>>birth_year;
// print the output
cout<<birth_month<<"/"<<birth_year<<endl;
return 0;
}
Explanation:
Declare two variables to store the birth month and birth year.Read the inputs from the user and assign it the variables.Print the birth month and year separated by a slash "/".
Output:
enter birth month:1
enter birth year:2000
1/2000
