Answer:
(a)Yes, it is an exponential function.
(b)
Step-by-step explanation:
(a)A population grows exponentially if it increases by a common ratio(called the growth ratio). We can see from the given information that the population of E.coli doubles every 20 minutes, therefore it is an exponential growth with a growth ratio of 2.
(b)The population, P(t) at any time t of an initial population, 
with a growth ratio of r over a period k can be modeled using the function:
In this Case:
=200
Growth rate,r=2
Growth Period,k=20 minutes
Therefore, the equation that models the function is:
, t is in minutes
Answer:
n=2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
11−8n=1−3n
11+−8n=1+−3n
−8n+11=−3n+1
Step 2: Add 3n to both sides.
−8n+11+3n=−3n+1+3n
−5n+11=1
Step 3: Subtract 11 from both sides.
−5n+11−11=1−11
−5n=−10
Step 4: Divide both sides by -5.
−5n
−5

Answer:
625
Step-by-step explanation:
First, you have to convert 0.2 grams to mg. To do this, multiply 0.2 by 1000. This yield 200. Now 200 is what percent of 32.
200 * 100 / 32
= 625
