Well first lets find the ROC (rate of change) in the sets of data.
1990 -> 134
2000 -> 139
so lets find the difference from the years given
2000-1990=10 so there is a 10 year gab
139-134=5 so there is a 5 million increase in the population
so divide 10 by 5 which gives us 2, so every year there is a 2 million increase in the population. so from 2000 to 2014 there is 14 years, so
14 x 2= 28, then add that to the latest population data
139+28=167
so the population in 2014 would be 167 million
Hope this helped!!
Answer:
(-5, 5)
Step-by-step explanation:
Answer:
Exponential growth function: P = 1700*e^(0.02*t)
After 10 years, the amount of population will be 2076
Step-by-step explanation:
Population growth is modeled by the following equation:
P = P0*e^(r*t)
where P is final population, P0 is initial population, r is rate of growth (as decimal) and t is time (in years)
Replacing with P0 = 1700, r = 0.02 and t = 10, we get:
P = 1700*e^(0.02*10) = 2076.38
Answer:
(15+3d)/6 = c
2 1/2 + 1/2d = c (more simplified)
Step-by-step explanation:
15 = -3(2c +d)
15 = -6c -3d
+3d +3d
15 +3d = -6c
/-6 /-6
(15+3d)/6 = c
2 1/2 + 1/2d = c
