Time is C. 50 seconds
Step-by-step explanation:
The population of bacteria at time t here is given by

where
b is the number of bacteria
t is the time in seconds
Here we want to find the approximate time at which the number of bacteria is
b = 625
Substituting into the equation and solving for t, we find:

Therefore, the solution is
C. 50 seconds

Answer:
11x2 + 2x-13
Step-by-step explanation:
We must build the new function f-g, which turns to be a sum between polynomials.
f(x)-g(x)= 12x+20 + 11x2- 10x-33
f(x)-g(x)= 12x+20 + 11x2- 10x-33
f(x)-g(x)= 11x2 + 2x-13
The circumference<span> of a circle is the distance around the circle. </span>The circumference of a circle is calculated by the expression:
Circumference = 2πr
Circumference = 2π(30 inches)
Circumference = <span>94.2 inches
</span>
Therefore, the correct answer from the choices listed above is option C. Hope this answers the question.

Step-by-step explanation:
Answer:
18cm
Step-by-step explanation:
Given:
- The length of AB is 9 centimeters
- A dilation with a scale factor of 2
The length of the image AB after the dilation is applied:
9 x 2 = 18
dilation is used to make an image or in this case AB, with a scale factor of 2 means that its doubling in size. If the scale factor was 1/2 that it would be decreasing in size since it will be half of the original size
