There’s nothing shown up for it sooo...can you type it out so I can help
For this case we have that by definition the area of a rectangle is given by:
Where
- <em>w: width of the rectangle
</em>
- <em>l: length of the rectangle
</em>
The area of the original rectangle is given by:
The area of the new rectangle is given by:
Therefore, the original area increases with a factor of 9.
Anwer:
the original area increases by a factor of 9.
The doubling time is a characteristic unit (a natural unit of scale) for the exponential growth equation, and its converse for exponential decay is the half-life. For example, given Canada's net population growth of 0.9% in the year 2006, dividing 70 by 0.9 gives an approximate doubling time of 78 years.
First you take 7143-6997 to get her units used( it’s 146) since you know that the first 100 units cost 24p per unit so take 100 Times 24 p to get 2400p then take the remaining 46 units times 16 to get 384p.
Add 2400p+384p to get 2784p for her bill
