A 48 gram sample of a substance that’s used for drug research has a k value of 0.1325
Lyrx [107]

Using an exponential function, it is found that the half-life of the substance is of 5.23 units of time.

<h3>What is the exponential function for the amount of a substance?</h3>

The function is given by:

A(t) = A(0)e^{-kt}

In which:

  • A(0) is the initial value.
  • k is the exponential decay rate.

The parameters are given by:

A(0) = 48,  k = 0.1325.

Hence the equation is:

A(t) = 48e^{-0.1325t}

The half-life is the amount of time for which A(t) = 0.5A(0) = 24, hence:

A(t) = 48e^{-0.1325t}

24 = 48e^{-0.1325t}

e^{-0.1325t} = 0.5

\ln{e^{-0.1325t}} = \ln{0.5}

0.1325t = -\ln{0.5}

t = -\frac{\ln{0.5}}{0.1325}

t = 5.23.

Compare using &lt;, &gt;, or =. 7 2/5___ 7 3/8
katrin [286]

Answer:

<

Explanation:

Step 1 - Convert the mixed numbers into decimals

7 2/5

2/5 • 20/20 = 40/ 100

40/ 100 = 0.4

0.4 + 7.0 = 7.4

Therefore, 7 2/5 = 7.4

Step 2 - Convert the mixed numbers into decimals

7 3/8

3/ 8 = 0.375

0.375 + 7.0 = 7.375

Therefore, 7 3/8 = 7.375

Step 3 - Compare

7.4 < 7.375

So, 7 2/5 is less than 7 3/8
