25. A post-doctoral research student is working with a culture of bacteria that doubles in size every 72 hours. The initial popu

ale4655 [162]

Answer:

$P=750 e^{0.00963t}$

The population size would be 753,190 after 30 days

Explanation:

Since, the population growth function is,

$P = P_0 e^{rt}$

According to the question,

if t = 0, P = 750,

$\implies 750 = P_0 e^0\implies P_0 = 750$

Also, if t = 72, P = 1500,

$\implies 1500 = P_0 e^{72r}\implies 1500 = 750 e^{72r}\implies 2 = e^{72r}\implies \ln 2 = 72r\implies r = \frac{\ln 2}{72}\approx 0.00963$

Hence, the required function would be,

$P=750 e^{0.00963t}$

If t = 720 hours ( 30 days = 720 hours ),

Then, the population after 30 days would be,

$P=750 e^{0.00963\times 720}=750 e^{6.912}=753190.30695\approx 753190$

Leann is learning about chemical reactions. She wants to create a model of a chemical reaction, so she is examming the informati

butalik [34]

Answer:

B the kinds of molecules involved in the reaction
C the kinds of elements that make up a molecule
D whether the molecules are products or reactants

Explanation:

When modelling the chemical reaction, it is important that the process is explained such that people looking at the model understand what happened in terms of the reactants and products and how they came to be either.

Leann will therefore have to include the kinds of molecules involved in the reaction be they products or reactants. She will also have to include which elements make up the molecules for instance a water molecule would have the elements Hydrogen and Oxygen.

Finally she would have to indicate which molecules are reactant and which are products. Reactants usually stay to the left side of the reaction equation and products stay to the right.
