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

72 is the answer to this problem

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
