If there is an about page where it tells whom made the website, as well as a copyright 2016 on the bottom of the page. This basically means the website is useful and updated by the creators. Another factor which the site doesnt always need but if it has an https at the beginning of the url then it should be good and valid because that means the site is secured. Also factor in the sections where articles are present, if they have a date and an author towards the bottom or top of the article, then it can be trusted as well. Theres a lot more you can look for in a site and validating if it is an okay site but these are a few examples. Hope this helped!:)
Answer:
You don't really need the for loop to calculate B square.
The element-wise multiplication operator can help you get the square of each element of B.
B = [1, 2 3; 4, 5,6; 7,8,9];
B = B.^2;
Hope this helps!
Answer:
If you want to use a js variable in a php script you MUST pass it within a HTTP request. There are basically two ways: Submitting or reloading the page.
Explanation:
In programming, just like in algebra, we use variables in expressions (total = price1 + price2). From the example above, you can calculate the total to be 11. JavaScript variables are containers for storing data values. All JavaScript variables must be identified with unique names. These unique names are called identifiers.
Answer:
total = 0
items = int(input("Enter the number of items ordered: "))
for i in range(items):
price = float(input("Enter the price of item " + str(i+1) + ": "))
total += price
if total < 200:
total += (items * 10)
print("Bill is $" + str(total))
Explanation:
*The code is in Python.
Ask the user to enter the number of items ordered
Create a for loop that iterates depending on the number of items ordered. Inside the loop, ask the price of each item and add it to the total
After the loop, check the total. If it is smaller than 200, add 10 for each item to the total
Print the total
