For the answer to the questions above,
A) Parrots are following a Geometric Progression of 15% increase.
20(1.15), 20(1.15)², 20(1.15)³,
Function = 20(1.15)^n Where n is at the end of year, n =1, 2, 3, ..
Snakes are increasing by 4.
28, 32, 36,....
Function = 24 + 4n n = number of end year, n =1, 2, 3,...
<span>B) After 10 years: </span>
Parrot = 20(1.15)¹⁰ = 80.91115471
Snakes = 24 + 4(10) = 64
<span>C) After what time they are the same: </span>
We use trial and error:
Test: n 20(1.15^n) (24 + 4n)
1 23 28
2 26.45 32
<span> 3 30.41 36 </span>
4 34.98 40
5 40.23 44
6 46.26 48
7 53.20 52
8 61.18 56
9 70.36 60
After year 7, the Parrots increases far more.
<span>At year 7 they are roughly the same.</span>
<span>Option D. Total number of traffic accidents per year, by means of a bar chart that shows the difference of given values and that are represented by size, length and color. This to know the number of accidents that occur as first information. Also the option C. The decrease number of traffic accidents per year, the same with a bar chart that represents the data and its different results thrown. This is to determine the decrease, after knowing the annual number of accidents. This also helps to know the number of current accidents, increase, decrease and the main causes of accidents in large cities.</span>
