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.

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%.

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

A(t) = A(0)(1 - r)^t

In which:

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

In this problem, the function is:

M(t) = 200(0.96)^t

Hence:

1 - r = 0.96

r = 0.04

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

Maria Louisa looks at a sequence of shapes and records the number of vertices in each of the shapes in the sequence. The first s
seropon [69]

Step-by-step explanation:

arithmetic sequence.

an = an-1 + c = a1 + (n-1)c

c is in our case 2 (every new shape has 2 more vertices).

we have a a1 = 3.

an = 3 + 2(n-1)

so,

a21 = 3 + 2(20) = 3 + 40 = 43

the 21st shadow will have 43 vertices.

valkas [14]

Answer:

r^12 no r^6

Step-by-step explanation:

I was wrong it is r^6 r−9(−3) r−9+3=r−6

  • r-6 becomes 1 over r6

The experimental probability that in a group of 4 students, at least one of them has brown eyes is 95%.

<h3>What is Experimental Probability?</h3>

Experimental probability is a probability that is determined on the basis of a series of experiments. A random experiment is done and is repeated many times to determine their likelihood and each repetition is known as a trial. The experiment is conducted to find the chance of an event to occur or not to occur.

Here , Favorable Outcome = 19

          Total outcomes = 20

Probability = Favorable Outcome/ Total Outcome

                   = 19 / 20

                   = 95%

Thus, the experimental probability that in a group of 4 students, at least one of them has brown eyes is 95%.
