Answer 1

Answer:

The treatment decays by half each week.

Step-by-step explanation:

The decay function is given by:

$y=a(1-r)^{t}$

Here,

y = final value

a = initial value

r = decay rate

t = time

The decay function for one medications to treat dogs for fleas is:

$F(x)=4\cdot (\frac{1}{2})^{w}$

Here the decay rate is:

$1-r=\frac{1}{2}\\\\r=1-\frac{1}{2}\\\\r=\frac{1}{2}$

The treatment decays by half each week.
