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.
