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

The answer is 308 by multiple
3 x 3 = 9
3 + 3 = 6
Explanation:
3 works for both cases
<span>Complementary angles sum up to 90 degrees and supplementary angles sum up to 180 (I remember that because they are alphabetical).
90 - 71.4 = 18.6
180 - 71.4 = 108.6
Therefore, D. is the answer.</span>
