Yui makes a list of the balances in her savings account at the end of each month. she notices that each month’s total is 5% greater than the previous month’s total. she writes a recursive formula to describe the account balances.

which value should she use as the common ratio?

0.05
0.5
1.05
5.0

1.05

Step-by-step explanation:

Given: Yui makes a list of the balances in her savings account at the end of each month. She notices that each month’s total is 5% greater than the previous month’s total.

Let the first term be =x.

Then the second term will be :-

Now, the common ratio will be given by :-

Therefore, the common ratio for the given problem will be :-

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
