The graph shows the growth rate of a certain bacteria in a lab, where the number of bacteria depends on the number of hours sinc
1 answer:
The approximate number of bacteria after 16 hours is 60 bacteria ,Option C is the right answer.
<h3>What is a Function ?</h3>A function is a Mathematical statement which connects a dependent variable and an independent variable.
The graph shows the the growth rate of a certain bacteria in a lab
the number of bacteria is on the y axis and
the number of hours is on the x axis
The function is continuous ,
From the graph the approximate number of bacteria after 16 hours is
60 bacteria
Therefore Option C is the right answer.

Answer:
Yes, "y" varies directly with "x".
The equation is:
Step-by-step explanation:
By definition, Direct variation equations have the following form:
Where "k" is the Constant of variation.
If you solve for "k", the equation is:
Then, given the table provided in the exercise, you can know if "y" varies directly with "x" by finding the quotient of the correspoding values of "x" and "y":
- Dividing by
you get:
- Divide by
:
- Dividing by
:
Since the quotient is constant, then "y" varies directly with "x" and the the Constant of variation is:
Therefore, the equation for the Direct variation is:
