Step-by-step explanation:
To solve 4/9 + 9/18 just find the common denominator which is 18.
to get 4/9 to get the denominator of 18 you multiply the denominator by 2:
9 x 2 = 18, what you do to the bottom you do to the top (Multiply the numerator by 2 also) so, 4 x 2 = 8.
Now, add the numerator and keep the denominator the same. 8 + 9 = 17.
8/18 + 9/18 = 17/18
Answer:
Decay function, 70% per year.
Step-by-step explanation:
A general exponential function is defined as
...(1)
where, a is initial value, |r| is rate of change and x is time in years.
If r>0, then it is a growth function and if r<0, then it is a decay function.
The given function is
It can be rewritten as
...(2)
On comparing (1) and (2), we get
Since r<0, therefore the given function is a decay function.
Therefore, the given function decreasing by 70% per year.
