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? 0.011 0.089 0.989 1.011
1 answer:
Using exponential function concepts, it is found that the common ratio would be given by 0.989 .
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:
In which:
A(0) is the initial value.r is the decay rate, as a decimal.1 - r , also as a decimal, is the common ratio.
In this problem, the amount decays 1.1% a year , hence:
1 - r = 1 - 0.011 = 0.989.
The common ratio would be given by 0.989 .

Given
Paige earns
She worked
Quarter sale
If Paige gets
Then the commission she gets in a quarter is
So the amount she earns
(5/8) × 48 = (8/15) × n
Multiply by the inverse of the coefficient of n. That inverse is 15/8.
n = (15/8)×(5/8)×48 = (75/64)×48 = 225/4 = 56 1/4
5/8 of 48 is equal to 8/15 of 56 1/4
Call Martha's age 5 years ago is x So Martha father's age five years ago is 7x We have : 7x + 5 = 4(x + 5) 3x = 25+5=30 so x = 5 so Martha's present age is 10 and her's father's present age is 40 Brainliest?
