Question

If an exponential model has a 9% decay rate,

what multiplier would be used in the function
model?
0.9 1.09
1.9 0.91

Answer 1

Answer: 0.91

=====================================================

Step-by-step explanation:

If you lose 9% of a substance, then you keep the remaining 91% because 100% - 9% = 91%. Or you can think of it as 91% + 9% = 100%

Then we convert 91% to decimal form to get 0.91

-----------

Or you can do the steps like this:

9% = 0.09

1 - 0.09 = 0.91
