which part of the graph is not realistic give reasons
Answers
where's the graph dear?
Answer:
In realistic situation, the body cannot have more than one velocity at the same instant OR in other words, each axis vertical with time axis must intersect the curve only at once.
In Maths Literacy, almost every problem begins with a story, which then needs to be analysed and solved (if possible). It is easier to understand the meaning of a picture than a list of numbers. A graph is just a mathematical picture of the relationship between two quantities, such as distance and time. The advantage of a graph is that you can see and understand the whole picture at a glance.
In this section we will look at the messages that graphs give us. You will develop the skill of interpreting graphs and you will learn to identify some important features of graphs.
Graphs going up and going down (increasing and decreasing) (EMG37)
WORKED EXAMPLE 1: LOOKING AT A GRAPH IN A NEWSPAPER
Jabu sees the following graph in a newspaper article:
What information can Jabu extract from this graph?
The graph shows the inflation rate for each year for seven years.
Following the line of the graph, you can see that inflation increases (goes up) in general.
The graph is steepest in the last year. This means that inflation increased the most during this time.
Inflation
The increase in the price of goods in a country.
If a graph is increasing, the slope goes up from left to right.
If a graph is decreasing, the slope goes down from left to right.
How do we know when a line is steeper than another line? You can see the difference by looking at the slope or gradient:
A steeper graph shows a quicker change.
A gradual slope shows a slower change.
