A country's population in 1992 was 72 million. In 1998 it was 76 million. Estimate the population in 2012 using the exponential

stepan [7]

We assume the annual percentage increase is the same. We will work out the constant k using the formula

We have
P = 76
A = 72
t = 6 years (from 1992 to 1998)

Substitute into the formula
$76=72e^{6k}$
$\frac{76}{72}=e^{8k}$
Take log both sides give
$ln( \frac{76}{72})=ln(e^{6k})$
$0.05406722127=6k$
$k=0.009$

We can now work out the number of population by the end of 2012 using the formula

We have
A = 72 million
k = 0.009
t = 10 years (1992 to 2012)

$P=72e^{0.009*10}$ $P=78.78$ ≈79 million

Need help one step equations multiplication and Division

FromTheMoon [43]

16. 27/20 = k/2

Switch sides. (Optional)
k/2 = 27/20

Multiply them by 10.
k/2 × 10 = 27/20 × 10

Simplify.
5k = 27/2

Divide both sides by 5.
5k÷5 = 27/2÷5

Simplify.
k= 27/10
