lisabon 2012 [21]

In 9 days, the number of bacteria in the culture will reach 800,000.

  • A process called exponential growth sees a rise in quantity over time. It happens when a quantity's instantaneous rate of change with respect to time is equal to the quantity itself.
  • B = 50[10^(d/2)]
  • Small, single-celled creatures called bacteria exist. Nearly all areas of the world are home to bacteria, which are essential to its ecosystems.
  • A microbiological culture, also known as a microbial culture, is a technique for growing microbial organisms in a controlled laboratory environment while allowing them to reproduce in a predefined culture medium. In molecular biology, microbial cultures are fundamental diagnostic techniques that are employed as research tools.
  • We want to find the number of days to reach 800,000 bacteria in the culture.
  • 800000 = 50[10^(d/2)]
  • 16000 = 10^(d/2)
  • d/2 = log_{10} 16000
  • d/2 = 4.204
  • d = 8.408
  • d = 9 days

Write 1.5% as a fraction
lutik1710 [3]
With percentages it is useful to know that cent is 100 in Latin. So think of percent as PER-100. So 1.5% is 1.5 per 100. i.e 1.5/100.

To avoid having a decimal as your numerator write it as 3/200

Which expression is equivalent to
lutik1710 [3]

Answer:

\frac{\sqrt[4]{3x^2} }{2y}

Step-by-step explanation:

We can simplify the expression under the root first.

Remember to use  \frac{a^x}{a^y}=a^{x-y}

Thus, we have:

\sqrt[4]{\frac{24x^{6}y}{128x^{4}y^{5}}} \\=\sqrt[4]{\frac{3x^{2}}{16y^{4}}}

We know 4th root can be written as "to the power 1/4th". Then we can use the property  (ab)^{x}=a^x b^x

<em>So we have:</em>

<em>\sqrt[4]{\frac{3x^{2}}{16y^{4}}} \\=(\frac{3x^{2}}{16y^{4}})^{\frac{1}{4}}\\=\frac{3^{\frac{1}{4}}x^{\frac{1}{2}}}{2y}\\=\frac{\sqrt[4]{3x^2} }{2y}</em>

<em />

<em>Option D is right.</em>
