In the case of bacteria, we use the continuous growth equation:
Final=Initial×e∧(r×t)
In other words, the final amount is equal to the initial amount times e to the rate times time. In order to find your rate, you would plug in the numbers as follows:
3600=3000×e∧(6r)
Therefore: r=0.03
Next, you would plug in the r value and 13 hours into the equation to solve for the final amount.
F=3000×e∧(13×0.03)=4,453 bactera after 13 hours
Answer:
is no x-intercept
Step-by-step explanation:
A negative discriminant means that the parabola has no real roots (only imaginary roots.) Roots are where the parabola crosses the x-intercept and we know the parabola has no real roots, so it must never touch the x-axis. This means that the graph will have no x-intercept.
The answer is c. The problem can be solved graphically
