Answer:
Step-by-step explanation:
As per the given question
As we know that
f(x) and x are related by following equation
where
b is the common ratio
Now first we have to compute the value for b which are as follows
Like if we take the ratio by this method than it comes 1.25
Therefore the common ratio, b = 1.25
So,
a = 5,120
Hence, the equation which model the relationship between the number of weeks and the number of viewers is
Answer:
The function to determine the value of your car (in dollars) in terms of the number of years t since 2012 is:
Step-by-step explanation:
Value of the car:
Constant rate of change, so the value of the car in t years after 2012 is given by:
In which f(0) is the initial value and r is the decay rate, as a decimal.
In 2012 your car was worth $10,000.
This means that , thus:
2014 your car was worth $8,850.
2014 - 2012 = 2, so:
We use this to find 1 - r.
Thus
