Answer:

Step-by-step explanation:
1) q=90/180=45/90=...=1/2;
2) the formula of the n-th term of the given sequence is:

3) according to the formula 15th term is:

or ≈0.011.
The example in that question, the age of Roger is the independent variable. This means that the variable left is <span>granola bars. This make it the dependent variable since it depends on the age of Roger.
The age does not depend on the amount of </span>granola bars eaten by Roger but the amount of <span>granola bars may depend with age of Roger.</span>
Answer:
To see if multiple ratios are proportional, you could write them as fractions, reduce them, and compare them. If the reduced fractions are all the same, then you have proportional ratios.
A. They are both proportional because they have the same ratio.
b. The two graphs are the same because they have a constant rate of change (50), but they have different y-intercepts.
