Step-by-step explanation:
The exponential relation can generally be represented as ;
y = I (1 + x)^n
where I is the initial value
1 + x represents the growth rate
n represents the time such as number of years
y represents the value after n count
a) The value 1200 represents the initial count of bacteria in the study
b) 1.8 represents the growth rate of the bacteria population in the culture
c) 1000 represents the initial bacteria population in the second function
The difference mean that the initial population in the first case study is greater than what we have in the second function
Answer:
i think a is 6912:)
i thin b is 359424:)

Answer:
Step-by-step explanation:
a ) The worth of Jean-Claude's gnome after 1 year
= 80000 x 1.02
= £81600
b ) common ratio of geometric progression
= 81600 / 80000
= 1.02
c ) worth after 10 years
= 80000 x 1.02¹⁰
= 80000 x 1.21899
= £97519.55
d )
120000 = 80000 x 
1.5 =
ln1.5 = k ln 1.02
k = ln 1.5 / ln 1.02
= .4054 / .0198
= 20.47 years .
