Find the slope of the line connecting (1990,435000) and (2005,482300):
482300-435000 47300
m = ----------------------- = ---------------- = 3153/yr (approx)
2005 - 1990 15 yr
Use the point-slope formula to find the equation of this str. line:
y-435000 = (3153/yr)(x-1990)
The year 2020 is 30 years after 1990. Thus, the expected pop in 2020 is
given by y-435000 = 3153(30) = 94590, so that y = 529590.
M/n=p-6
n= m/(p-6)
i swapped the n and p-6
Yes -5/0 is undefined because having 0 of something means you cannot split that 0 into any number so the answer is undefined.
3916 so estimated it will be 3900
Domain: {-3}
