You do this
8 2
---- = -----
20 5
So the scale factor is 2/5
8 is the first.
Reasoning:
So we know what the Fibonacci sequence is. To get the next number, you add the number behind it, by the number behind that.
For example, these are the first 5 Fibonacci numbers.
1, 1, 2, 3, 5.
1 + 0 = 1.
So 1 is the second number.
1 + 1 is 2.
So 2 is the third number.
2 + 1 = 3.
So 3 is the fourth number.
3 + 2 = 5.
So 5 is the fourth number.
The problem:
If the fifth term is 49, and the fourth term is 30. We can subtract 49 by 30, to find the third number, and so on.
49 - 30 = 19.
So 19 is the third number.
30 - 19 = 11.
11 is the second.
19 - 11 = 8.
8 is the first.
Answer:
Horizontal asymptote of the graph of the function f(x) = (8x^3+2)/(2x^3+x) is at y=4
Step-by-step explanation:
I attached the graph of the function.
Graphically, it can be seen that the horizontal asymptote of the graph of the function is at y=4. There is also a <em>vertical </em>asymptote at x=0
When denominator's degree (3) is the same as the nominator's degree (3) then the horizontal asymptote is at (numerator's leading coefficient (8) divided by denominator's lading coefficient (2)) 
If the number was x, then you could write the expression x-5 since you show five less or subtracted from the number. Hope this helps.
