Answer:
1)A formula is an equation that makes calculations based on the data in your spreadsheet. Formulas are entered into a cell in your worksheet. They must begin with an equal sign, followed by the addresses of the cells that will be calculated upon, with an appropriate operand placed in between.

This page sets out some of the basics behind drawing and creating good graphs and charts. By ‘good’, we mean ones that show what you want them to show, and don’t mislead the reader.Types of ChartsThere are several different types of charts and graphs. The four most common are probably line graphs, bar graphs and histograms, pie charts, and Cartesian graphs. They are generally used for, and are best for, quite different things.

You might, for example, want to show how a budget had been spent on different items in a particular year.

They are used when you have data that are connected, and to show trends, for example, average night-time temperature in each month of the yea
plz mark me brainiest..
Answer:
1.a group of signs, letters or numbers used in science or mathematics to express a general law or fact
2.The four most common are probably line graphs, bar graphs and histograms, pie charts, and Cartesian graphs. They are generally used for, and are best for, quite different things. You would use: Bar graphs to show numbers that are independent of each other.
3.i)Computer hardware includes the physical parts of a computer, such as the case, central processing unit (CPU), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard. By contrast, software is the set of instructions that can be stored and run by hardware.
II) In formal language theory and computer programming, string concatenation is the operation of joining character strings end-to-end. For example, the concatenation of "snow" and "ball" is "snowball". In certain formalisations of concatenation theory, also called string theory, string concatenation is a primitive notion.
4.Chart area. Chart title. Legend. Axis title.
Axis lines/values. Tick marks. Plot area.
Chart series.
5.There are two types of cell references: relative and absolute. Relative and absolute references behave differently when copied and filled to other cells. Relative references change when a formula is copied to another cell. Absolute references, on the other hand, remain constant no matter where they are copied.
6.The benefits of using a GUI are multiple.
Apart from the fact that it provides users with an intuitive and easy-to-use interface and immediate visual feedback,
a GUI also allows a user to open up multiple programs or instances and displays these simultaneously
7.Functions are usually represented by a function rule where you express the dependent variable, y, in terms of the independent variable, x. A pair of an input value and its corresponding output value is called an ordered pair and can be written as (a, b)
8.There was no operating system. ... This is why an operating system is needed. It allows a program to run on multiple different types of hardware. An operating system provides a layer between the program and hardware to enable a program to use a standard interface no matter what hardware is used.
9.A function is a group of statements that together perform a task. ... A function declaration tells the compiler about a function's name, return type, and parameters. A function definition provides the actual body of the function. The C standard library provides numerous built-in functions that your program can call
10.i) Multi-user software is software that allows access by multiple users of a computer. Time-sharing systems are multi-user systems. Most batch processing systems for mainframe computers may also be considered "multi-user", to avoid leaving the CPU idle while it waits for I/O operations to complete.
II)A command-line interface processes commands to a computer program in the form of lines of text. The program which handles the interface is called a command-line interpreter or command-line processor
