Answer:
<em>The Estimate for the population in 2008 is 33 million </em>
Step-by-step explanation:
<u>Exponential Function</u>
Some real-life situations can be modeled by using the exponential function which takes the form
Where A and k are constants, and t is the independent variable.
We are given two data. A country's population in 1992 was 28 million and in 1999 it was 30 million.
Let's express P as the population in million and t the time in years elapsed since 1992.
The information can be written as two points: (0,28), (7,30). Please recall that the second data comes from the year 1999, seven years after the zero reference.
We only have to replace both points in the general form:
We know A=28 million
Also
Taking logarithms
Solving for k
The model is complete now:
For the year 2008, t=2008-1992=16 years
The Estimate for the population in 2008 is 33 million
Answer:
Step-by-step explanation:
In order to solve for and we want to solve for , we want to get m on one side of the equation.
Let’s subtract b from both sides.
Now we can divide both sides by x so we have m on one side of the equation.
Hope this helped!

Answer: 1967
Step-by-step explanation:
Ada was 15 years when her sister Ngozi was 18 years.
This means that Ngozi is older than Ada by:
= 18 - 15
= 3 years
If Ngozi is older by 3 years, this means that she must have been born 3 years earlier than Ada
If Ada was born in 1970, Ngozi was born:
= 1970 - 3
= 1967
