X^2 + 4x - 12 = 0 is easily factorised into (x + 6)(x - 2). When we set this to 0 we can then say (x + 6) = 0 and (x - 2) = 0. At this point we can say for (x + 6) = 0 | (x) must equal x = … Read more

5(t-6) + 5(2t+2) - 8 = 5t - 30 + 10t + 10 - 8 |-> This becomes: 15t - 28. To get the value of (t) then t = -28/15. Which is around -1.68....8

Query language more-so (SQL) is a way of looking for information on a given criteria whereas tailored programs tend to have hard coded search processes. Addition to this, SQL, Oracle etc languages are tailored to the programmer not the user so during the development stages, adaptions can be made for the program and at this … Read more

Through tables, and the relations between them which keeps the data consistent. The structure of the data is mostly put down to the gathered information for example; If I had a business that handled credit/debit card details and I wanted to structure the data into a database. I wouldn't stick all the information on one … Read more

Create a float function to return the value of the area from two specified numbers; Note: "You can use integers but it's advised to use floats to return the decimal values for exact accuracy." float cArea(float width, float height) { float _cArea = width * height; return _cArea; } You should manipulate the bolded code … Read more

However... SMTP just stands for simple mail transfer protocol. It's one of a few email/communication protocols we use over the internet and our networks to send emails. FTP is what we call the file transfer protocol. This is more-or-less self-explanatory; but it's what we use to handle the process of transfer data across network interconnects … Read more

Database is obviously a more managed entity therefore there is more validity and integrity when storing data all at the cost of less work which save a company a lot of storage, money, and time. If you were to manage data through file allocation then you would need something remember which file the data is … Read more

Advantages would come when you have a devlopment team... You could explain what a function does or short note the key processes of a function. It could also help the programmer read-back the code he's written so he doesn't get confused as code on large programs sometimes become tedious to read through and 'sus' out. … Read more

First 1! & 2! Looks like your after the factorial which the factorial 1! Is 1 and the factorial of 2! Is 2 so just swap these numbers with 1 and 2 as shown below the code you need to write has been bolded for you. You must be using java.lang.math to bring in the … Read more
