Answer:
In 2010 the population become 206,123,000.
Step-by-step explanation:
Consider the provided equation.
Where P represents the population in millions.
We need to determine the year in which the country had population of 206,123,000.
As P is in millions so divide 206,123,000 by one million.
Substitute P = 206.123 in above equation.
30 year from 1980 the population become 206,123,000.
In 2010 the population become 206,123,000.
Answer:
b = 9
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
b² + 12² = 15²
b² + 144 = 225 ( subtract 144 from both sides )
b² = 81 ( take the square root of both sides )
b = = 9
