Answer:
40
Step-by-step explanation:
The scale factor of 5 to the side measuring 8 means that you multiply that side by the scale factor.
Basically, the equation would go like this:
Original Side Length: x
Scale Factor: y
New Side Length: z
xy=z
If we plug in our numbers, we get:
8*5=z
40=z
<u>40</u>
So, let's first focus on the first year:
the population then would be: 23000* (100+2)%
100% is the old population the 2% is the incease, so in total it's 102%, or 1.02 - the same number written differently.
So it will be 23000*1.02
After two years it will be 23000*1.02*1.02, and so on
so after x years it will be:
y=23000*
