If you would like to calculate the arithmetic mean, geometric mean, and harmonic mean from the following averages, you can calculate this using the following steps:
averages: 56.4, 59.8, 55.8
the number of values: 3
arithmetic mean:
(56.4 + 59.8 + 55.8) / 3 = 57.33
geometric mean:
(56.4 * 59.8 * 55.8)^(1/3) = 57.31
harmonic mean:
3 / (1/56.4 + 1/59.8 + 1/55.8) = 57.28

Answer: a) 236,000.
b) 2021
Step-by-step explanation:
Given : Population Growth The population P (in thousands) of Oriando,Florida from 1980 through 2009 can be modeled by  (1)
    (1)
where t = 0 corresponds to 1980.
Then , for 2009 
t= 2009-1980=29
a. ⇒The population of Phoenix in 2009 =  
 

Hence, the population of Orlando in 2009 was about 236,000.
b) Substitute p= 300 in (1) , we get
 
 
 (Divide both sides by 130)
 (Divide both sides by 130)
Taking Natural log on both sides, 


Hence, The year Orlando will have a population of 300,000 =1980+41 =2021
