Question

Please answer the question and please answer correctly... I really need help

Veterinarians use different medications to treat dogs for fleas. Once administered, the medication typically decays exponentially. One treatment decays by half each week

A dog receives 4 ml of medication and the function f gives the number of ml of medicine left after w weeks

F(x) = 4(1/2)^w

Answer 1

The treatment decays by half each week.

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 ((1)/(2))^(w)`

Here the decay rate is:

`1-r=(1)/(2)\\\\r=1-(1)/(2)\\\\r=(1)/(2)`

The treatment decays by half each week.
