The amount of mice that survive a new cancer treatment can be modeled by y = 25 (0.5)x. determine which number represents the decay rate.

0.5
2
x
25

0.5

Step-by-step explanation:

Given: The amount of mice that survive a new cancer treatment can be modeled by which is a exponential decay equation .

At x=0  ,

At x=1,

Let b be the decay rate, the decay rate of the given function will be

Hence, 0.5 is the number which represents the decay rate.
