Answer: A=12
Explanation:
4.5
The amount of chemical remaining after twelve seconds in the first reaction is:
A = 12 - 0.5(12)
= 12 - (6)
= 6
In the dissolved reaction, the amount of chemical loses half of itself every four seconds. This is the same thing as dividing by 2 every four seconds.
This is an exponential decay, so the amount of chemical divides by 4 every eight seconds, and by 8 seconds every twelve seconds. The amount remaining after twelve seconds in the second reaction is:
A' = 12/8
= 3/2
= 1.5
The difference between the amounts of chemical remaining is:
6 - 1.5 = 4.5
Therefore, A is 4.5 g greater than A' after twelve seconds.
In terms of communication, information is expressed either as the content of a message or through direct or indirect observation. That which is perceived can be construed as a message in its own right, and in that sense, information is always conveyed as the content of a message.
Information can be encoded into various forms for transmission and interpretation (for example, information may be encoded into a sequence of signs, or transmitted via a signal). It can also be encrypted for safe storage and communication.
The tool that can make chart 1 look like chart 2 is the data labels
<h3>What are Charts?</h3>
Charts are graphical ways of representing data elements.
Charts can be in form of:
From the diagram (see attachment), we can see that:
- Both charts are circle graphs
- The data label of chart 2 is visible, while the data label of chart 1 is not
So, the data label of chart 1 has to be made visible, for the chart to look like chart 2
Hence, the tool that can make chart 1 look like chart 2 is the data labels
