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>
Answer:
I'm not really sure which one you mean, but the exact form is 3/25 and the Decimal form is 0.12
Step-by-step explanation:
Answer:
5 boys to 9 girls
Step-by-step explanation:
Let x = the number of boys
Boys = x
Girls = x + 4
x + (x + 4) = 14
2x + 4 = 14
2x = 10
x = 5
This means that there are 5 boys. Since girls = x + 4, 5 + 4 = 9. There are 5 boys and 9 girls.
