Well first of all, let's define what an integer is...
Integers are numbers such as -2, -1, 0, 1, 2 etc etc.
------
If f(5)=12,
f(6)=0.3*f(6-1)
= 0.3*f(5)
= 0.3*12
= 3/10 * 12
= 36/10
= 3.6
We now know that f(6)=3.6
Now:
f(7)=0.3*f(7-1)
= 0.3*f(6)
= 0.3*3.6
= (3/10) * (36/10)
= 108/100
= 1.08
Answer:
f(7)=1.08
90 % sure
The image attached shows an operation that can be represented with whole numbers, becuase there are positive and negative characters.
So, we know by given that there are +4 circles and -7 circles, and the whole can be expressed as the algebraic sum of them,
Therefore, the model can be represented by the number -3, which is the whole because is the result of the operation that represent each type of element.
hope i helped
