The diameter of a bacteria colony that doubles every hour is represented by the graph below. What is the diameter of the bacteri

SOVA2 [1]

For this case we have a function of the form:

$y = A * (b) ^ x$

Where,

A: initial population of bacteria

b: growth rate

x: number of hours

Since the diameter is double every hour, then:

$b = 2$

We must now look for the value of A.

To do this, we evaluate an ordered pair of the graph:

For (1, 2):

$2 = A * (2) ^ 1$

Clearing A we have:

$2 = A * 2$

$A = \frac{2}{2}\\A = 1$

Then, the function is given by:

$y = 1 * (2) ^ x$

For after 9 hours we have:

$y = 1 * (2) ^ 9\\y = 512$

Answer:

the diameter of the bacteria after 9 hours is:

$y = 512$

Answer:

g(-3) = 1

Step-by-step explanation:

We use the top piece of the function since x = -3

g(-3) = x+4 and x = -3

g(-3) = -3 +4 = 1

One grocery clerk can stock a shelf in 20 min. A second clerk requires 45 min to stock the same shelf. How long would it take to

Lorico [155]

<u>Answer: </u>

clerk A and clerk B can simultaneously stock a shelf in $\frac{180}{13}$ minutes

<u>Explanation:</u>

Let the first clerk be A and the second clerk be B

A can stock a shelf in 20 min

B can stock a shelf in 45 min

Consider the complete work to be W

A’s rate of stocking = $\frac{W}{20}$ per minute

B’s rate of stocking = $\frac{W}{45}$ per minute

When, A and B work simultaneously, rate of work done = $\frac{W}{20}+\frac{W}{45}$

Total work done simulatenously = $\frac{W}{\frac{W}{20}+\frac{w}{45}}$

= $\frac{20 * 45}{20+45}$

Therefore, clerk A and clerk B can simultaneously stock a shelf in $\frac{180}{13}$ minutes
