Answer:
Population in 2013 is 132.76 ≈ 133 million.
Step-by-step explanation:
A country's population in 1990 was 123 million
In 2002 it was 128 million.
We have to calculate the population in 2013.
Since population growth is always represented by exponential function.
It is represented by
Here t is time in years, k is the growth constant, and is initial population.
For year 1990 ⇒
128 = =
taking ln on both the sides ⇒
ln
ln 128 - ln 123 = 12k [since ln e = 1 ]
4.852 - 4.81218 = 12 k
k =
For year 2013 ⇒
= 123 ×
= 123 × 1.07937
= 132.76 rounded to 133 million.
Therefore, population in 2013 is 132.76 ≈ 133 million.
Answer:
x ≤ 45
Step-by-step explanation:
Hi,
Since the band can reach 45 but no longer than that, we put the ≤ sign. And obviously, the x represents the number of mins.
I hope this helps :)
