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<1.For example y=12(0.95)^x, 0.95 is less than 1 so it is a decay factor. In other words, if the number in "b" is less than one it is decay factor, if bigger than one then it is a growth factor.
Find out about factors and factor trees.
You do a factor rainbow to find a prime factorization. You compare prime factorizations to find a greatest common factor.
You find the scale factor on a triangle by dividing the short side by the long side.
You need at least two factor trees to find a GCF.
You find a factor pair take the number that you want to find the factor pair of and divide it by a number. If the answer come out evenly then that's your factor pair EX. Factor pairs of 150 1 and 150 2 and 75 3 and 50 5 and 30 6 and 25 10 and 15
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.
Exponential growth has a growth/decay factor (or percentage decimal) greater than 1. Decay has a decay factor less than 1.

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
The growth and decay factor can be found using the formula ( a = e^{kt} ), where ( a ) is the amount after time ( t ), ( k ) is the growth (if positive) or decay (if negative) constant, and ( e ) is the base of the natural logarithm. If you know the initial value and the value after a given time, you can rearrange this formula to solve for ( k ). For exponential growth, you can use ( k = \frac{\ln(\text{final value}/\text{initial value})}{t} ). For decay, the process is similar, but ( k ) will be negative.
lack of use
it's the number you get after you subtract the growth rate by a 100 i am not shire about it :)
0.5714
Lack of improvements caused factories to decay.
The only reference I could find was Beta minus decay into Fluorine 21
Any number below negative one.
Some quantities decrease by a fixed proportion (not fixed amount) in each time period. Typical examples used in school mathematics are depreciation or radioactive decay. The value of an asset (often a car) is assumed to lose x% of its value every year. That is, at the end of each year, its value is (1-x/100) times what it was a year earlier. Similarly, radioactive substances lose y% of their mass through nuclear decay in each time period. The factor (1-x/100) is known as the decay factor.
