Aconservationist 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? 0.011 0.089 0.989 1.011

The common ratio is 0.989

Step-by-step explanation:

This is the case of an exponential decay. The function for exponential decay is,

where,

y(t) = amount left after time t  

y₀ = initial amount

r = rate of decay

t = number of periods

Putting r = 1.1% and t = n,

 ------------1

Putting r = 1.1% and t = n+1,

  ----2

Dividing eq 2 by 1,

where is the shape my dude?
