Answer:
≈ 8.07 mg
Step-by-step explanation:
Given
f(x) = 12
Substitute x = 1 into f(x) , that is
f(2) = 12(0.82)² = 12 ×0.6724 ≈ 8.07 mg
Answer:
19.995
Step-by-step explanation:
The answers should be 1D, 2C, 3B, 4A, and 5A.
This is a geometric sequence which represent exponential decay. For any sequence, if r^2, the common ratio squared, is less than one, it is exponential decay, or:
f=ir^t
If r^2<1, it is exponential decay. In this case r=2/3, so it is exponential decay.
