1 answer:
The population of bacteria after 40 hours is 254
Step-by-step explanation:
Initial population of bacteria = 40
Growth rate: Doubles every 15 hours
The population function is given as:
Here
P0 is the initial population
r is the growth rate
and t is the time in hours
The growth rate will be:
Putting the values in the function
Rounding off to nearest whole number we get

Answer:
D. -10, 10
Step-by-step explanation:
Instead of inserting values into x to solve, let's isolate x.
In order to do this, we must take the square root of both sides.
To find the square root of 100, we must figure out what = 100 when multiplied by itself. Reminder, it can be both a positive or a negative square root, as positive times positive is a positive, and negative times negative is a positive.
The square root of 100 is -10 or 10, as 10 x 10 or -10 x -10 = 100.
