Question

After a certain medicine is ingested, its concentration in the bloodstream changes over time.The relationship between the elapsed time, ttt, in minutes, since the medicine was ingested, and its concentration in the bloodstream, C(t)=95⋅(0.87)t

Answer 1

An exponential function has the following general form:

$f(x)=a^{rt}$

Where a i tcalled the common ratio and r is the rate of growth or depletion, in this case, we are given the following function:

$c(t)=95\times0.87^t$

As yu can see, the medicine shrinks by a factr of 0.87
