Answer: See below

Step-by-step explanation:

1 1/2 as mixed fraction = 3/2

3/4 + 3/4 = 3/2

2 2/3 as a mixed fraction = 8/3

7/3 + 1/3 = 8/3

a culture of bacteria starts with 505050 bacteria and increases exponentially. the relationship between bbb, the number of bacte
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

In two or more complete sentences, describe the transformation(s) that take place on the parent function, f(x)=log(x), to achiev
matrenka [14]
Transforming f(x) = log(x) to f(x) = log (2x) gives the effect of squashing the graph horizontally (by halving the x-coordinate)

Then from f(x) = log(2x) to f(x) = log (-2x) is reflecting on the y-axis

Then from log(-2x) to log(-2x-4) is to translate by 4 units to the right

Finally from log(-2x-4) to log(-2x-4)+5 is translating the graph up by 5 units

Which point is in the solution set of the given system of inequalities?
Feliz [49]

Answer:

(1/5, 9/5)

Step-by-step explanation:

Given the set of inequities

x+y>2..... 1

4x-y≥-1 .... 2

We are to get the solution point (x,y)

Solving simultaneously

From 1:

x>2-y

Substitute into 2

4(2-y)-y≥-1

4(2)-4y-y≥-1

8-5y≥-1

-5u ≥-1-8

-5y ≥-9

y≤9/5

Since x>2-y

x>2 - 9/5

x>1/5

Hence the required point is (x,y) = (1/5, 9/5)
