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?
a.0.05
b.0.5
c.1.05
d.5.0

1.05

Step-by-step explanation:

Given: Yui notices that each month’s total is 5% greater than the previous month’s total.

Let the initial amount in bank be x .

then the amount in the second month=

We know that the common ratio=

Hence, 1.05 is the common ratio.

answer: a

step-by-step explanation:

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
