What is the rate of decay for the function f(x) =2(0.95)^x ( x is on top of the parentheses)

SIZIF [17.4K]

Answer:

The decay rate is 5%.

Step-by-step explanation:

Let a substance is decaying at the rate of r% per hour from the initial value of P for t hours, then the final value of the substance is given by the function

$f(t) = P(1 - \frac{r}{100})^{t}$ ........... (1)

Comparing this equation with the original equation given as

$f(x) = 2(0.95)^{x}$ ............ (2) we get,

$(1 - \frac{r}{100}) = 0.95$

⇒ $\frac{r}{100} = 0.05$

⇒ r = 5%.

Therefore, the decay rate is 5%. (Answer)
