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

navik [9.2K]

Answer:

If Lance got home from school at 3:32 p.m. A and B both represent:

A: seventeen minutes before 3 would be before 3 o'clock even happens

B: 28 minutes before 4 would make more sense, since 3:32 is before 4 o'clock

Lance got home 28 minutes before 4

Hope this helps ;)

Determine whether the point (2, 2) is a solution to the system of equations. Explain your reasoning in complete sentences. Prove
goblinko [34]

Answer:

(0,2) is the solution of the given functions.

Step-by-step explanation:

We have been given two functions  f(x)=|x-1|+1  and g(x)=3x+2

To find the solution of the two functions mathematically, we will equate the given functions:

3x+2=|x-1|+1

3x+1=|x-1|

When we will open the modulus function we will have two values +, -

In positive case:

3x+1 =x-1

2x=-2

x=-1

Now, substitute x=-1 in g(x)=3x+2 we get

g(-1)=3(-1)+2=-1

Hence, (-1,-1) is the solution of the given functions.

In negative case:

Now, 3x+1=-(x-1)

3x+1=-x+1

4x=0

x=0

Now, put x=0 in g(x)=3x+2 we get

g(0)=3(0)+2=2

We have another solution: (0,2)

The point (2,2) is not the solution.

And graphically, the solution of two functions is their intersection point which is (0,2)

Hence, (0,2) is the solution of the function.
