Suppose the population of trout in a certain stretch of a river is 4000. in about how many years will the population of trout be 700 if the decay rate is 35%? use the equation 700 = (4000)(0.65)x and round the value of x to the nearest year.

4 years

Step-by-step explanation:

The exponential decay equation is given by :_

, where A is the initial population and r is the rate of decay in x years .

The initial population of trout in a certain stretch of a river =4000

The rate of decay = 35% =0.35

To find the number of years (x) for the population of trout be 700, we put all the values of the above equation, we get
