If we have y=a(b)^t as the equation then take b from this equation
case !: If b <1
then b=1-r
r=1-b
this r is the decay factor
case 2:If b >1
then b=1+r
r=b-1
this is the growth factor

What is the difference between exponential and nonexponential decay?
Perhaps a good way to explain the difference between exponential and nonexponential decay (like perhaps linear decay) would be to use some examples. In radioactive decay, which is exponential decay, the rate of decay is a function of the amount of material present. The more you have to start with, the more decays per unit of time. The less you begin with the smaller that number of decay events in a given period. And as the decay continues the number of decay events per unit of time decreases. (A consequence is that the material might never be seen to all "go away" in time.) Radioactive decay is a function of the amount of material undergoing decay, and the rate of decay is exponential. That is, when we write the equations for the phenomenon, we'll be using exponents in the expressions to account for the dependence of the decay rate on the amount of material present. There is a good comparison to this. Let's say a group of students is in a classroom and leaves at the bell. The all get up and hit the door, but the rate at which the students can get out is basically a function of the width of the doorway, and not how many students are trying to get out. This is easy to see. If the students go through the door at one student per second and 30 students were in the class, it will take 30 seconds for them to all leave. The rate of "decay" of the population in the room is constant at one student per second. It does not change. It was the same when all the students were trying to get out, and remains constant even as the last couple of students are trying to exit. It is a nonexponential "decay" scheme, and is, in fact, a linear one. The equation expressing the egress phenomenon will not have any exponents in it; all the terms will be what are called first order terms. No "powers" of a number or variable will appear. (A consequence is that the room will empty of students, and definitely so. This is a contrast to radioactive decay.)
What possible values can the growth factor have in an exponential decay equation?
Any number below negative one.
What is the difference between discount factor and discount rate?
Discount factor is the factor determining future cash flow, but multiplying the cash flow to obtain present value. Discount rate is used in calculations to equal the cost of capital.
Is 12 inches over 1 foot a rate?
It is a conversion factor but, it could be considered a rate [of conversion].
What is a decay factor?
it's the number you get after you subtract the growth rate by a 100 i am not shire about it :)
Which is a factor that determines the rate of sunken ship decay in the ocean?
currents, presence of marine animals, ship material
What is decay factor?
The constant factor that each value in an exponential decay pattern is multiplied by the next value. The decay factor is the base in an exponential decay equation. for example, in the equation A= 64(0.5^n), where A is he area of a ballot and the n is the number of cuts, the decay factor is 0.5.
How do you tell if its exponential growth or decay?
Exponential growth has a growth/decay factor (or percentage decimal) greater than 1. Decay has a decay factor less than 1.
Why do you think chemistry will not change the decay rate of an isotope?
It depends what is meant by 'decay'. It will not alter the atomic decay rate but elements can be chemically affected by the environment which can chemically decay them.
What is the decay rate of heart cells?
the decay rate of carbon is 14 in heart muscle cells,
What makes radioisotopes useful for dating objects?
They decay at a predictable rate.
Can paper decay?
Yes, but the rate of decay depends on the conditions.
As the temperature of a radioactive sample increases the rate of the nuclear decay?
It stays the same. Temperature has no effect on the rate of nuclear decay.
How the radioactive decay rate be changed?
The rate cannot be changed.
How do you find the decay factor?
To find the decay factor, you need to know the formula y=ab^x where "a" is the initial amount and "b" the growth or decay factor. It is a growth factor if the number next to "a" is bigger than 1, b>1, and it is usually in (). For example y=12(1.3)^x notice that (1.3) is bigger than 1 so it is a growth factor. The decay factor is "b" the same as growth factor but only that b
