a conservationist determines that a particular beach is eroding at a rate of 1.1% each year. when writing an explicit formula to represent the amount of beach remaining each year, which value should she use as the common ratio?\n0.011\n0.089\n0.989\n1.011

a conservationist determines that a particular beach is eroding at a rate of 1.1% each year. when writing an explicit formula to represent the amount of beach remaining each year, which value should she use as the common ratio?\n0.011\n0.089\n0.989\n1.011

Answer

Explanation:

Step1: Understand the erosion rate

The beach is eroding at a rate of 1.1% or 0.011.

Step2: Calculate the remaining amount

The remaining amount of beach each year is 1 - erosion rate. So, it is $1 - 0.011=0.989$. This 0.989 is the common - ratio for the geometric sequence representing the amount of beach remaining each year.

Answer:

C. 0.989
