Answer:
x=5
Step-by-step explanation:
x/6=15/18
18x=6 times 15
18x=90/18
x=5
The exponential equation is solved and the population in 2020 is given by the relation P ( A ) = 27,369
The exponential growth or decay formula is given by
x ( t ) = x₀ × ( 1 + r )ⁿ
x ( t ) is the value at time t
x₀ is the initial value at time t = 0.
r is the growth rate when r>0 or decay rate when r<0, in percent
t is the time in discrete intervals and selected time units
Given data ,
Let the initial population be P ( 0 ) = 4,200
Let the population in 10 years be P ( 1 ) = 5,000
Now , the population in 100 years is P ( 100 ) =
The exponential growth formula is given by
x ( t ) = x₀ × ( 1 + r )ⁿ
r = ln(5,000/4,200) / 10 = 0.017
Now we can use this value of r to predict the population in 2020, which is 100 years after 1920:
P(100) = 5,000 × e^(0.017 × 100) = 27,369
Hence , the predicted population of Centerville in 2020, assuming exponential growth, is 27,369
