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
Take log both sides give
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)
≈79 million

Answer:
- Slope = undefined
Step-by-step explanation:
<u>We know that:</u>
- Slope Formula = y₂ - y₁/x₂ - x₁
<u>Solution:</u>
- y₂ - y₁/x₂ - x₁ = -4 - 4/4 - 4
- => -8/0 = undefined
Since the slope of the line is un-defined, the line is vertical. Please look at my graph to understand better.
