Answer:
In mathematics, exponential decay describes the process of reducing an amount by a consistent percentage rate over a period of time. It can be expressed by the formula y=a(1-b)x wherein y is the final amount, a is the original amount, b is the decay factor, and x is the amount of time that has passed.

Answer:
5 is in the ten thousands place.
Step-by-step explanation:
Since the number to the left of 5, 2, is in the hundred thousands place, and the number to the right, 7, is in the thousands place, 5 is in the ten thousands place.
I hope this helped! :-)

. From here, you can graph it the way you would any other exponential equation by inserting values of x. For x=2, for instance, y=9.
