Clemence began studying a sample of the chemical element einsteinium- 253 253253, which naturally loses its mass over time. The relationship between the elapsed time, t tt, in days, since Clemence started studying the sample, and the total mass remaining in the sample, M ( t ) M(t)M, left parenthesis, t, right parenthesis, in milligrams, is modeled by the following function: M(t)=200⋅(0.96)t Complete the following sentence about the daily rate of change in the mass of the sample.

Respuesta :

Using exponential function concepts, it is found that the daily rate of change in the mass of the sample is of -4%, that is, the amount decays by 4%.

What is an exponential function?

A decaying exponential function is modeled by:

[tex]A(t) = A(0)(1 - r)^t[/tex]

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

In this problem, the function is:

[tex]M(t) = 200(0.96)^t[/tex]

Hence:

[tex]1 - r = 0.96[/tex]

[tex]r = 0.04[/tex]

1 - r < 1, hence the rate is negative, and the daily rate of change in the mass of the sample is of -4%.
