-7t=28
t=-4
Y=0-14 i think is the amswer
Answer:
that's it I think its clear
Answer:
0.03844
Step-by-step explanation:
0.62*6.2%
=0.62*0.062
=0.03844
The answer is 150 million.
Step 1. Calculate the growth rate.
Step 2. Calculate the population number in 2014.
We will use the formula for exponential growth:
A = P * eⁿˣ
where:
A - the final amount (value)
P - the initial amount (value)
e - the mathematical constant (e ≈ 2.72)
n - the growth rate
x - the time
Step 1:
A = 141 million = 141 000 000
P = 136 million = 136 000 000
n = ?
x = 2000 - 1991 = 9
Therefore:

Logarithm both sides of the equation:

Step 2:
Now when we know the growth rate, it is easy to estimate the population in 2016
A = ?
P = 141 000 000
n = 0.004
t = 2016 - 2000 = 16

Thus, the population will be nearly 150 million in 2016
