Question

What is the decay factor in y = 760(0.75)3?

Answer 1

Answer:

Decay factor is 0.75.

Step-by-step explanation:

The given function is  

$y=760(0.75)^3$     ...(1)

The general form of exponential decay function is  

$y=a(1-r)^t$    ...(2)

where, a is initial amount, t is the time period, r is decay rate and (1-r) is the decay factor.

On comparing (1) and (2), we get

$a=760, t=3, (1-r)=0.75$

Therefore, the decay factor is 0.75.
