A country's population in 1994 was 182 million. In 2002 it was 186 million. Estimate the population in 2004 using the exponentia

iogann1982 [59]

$\bf =ae^{kt}\qquad 
\begin{cases}
1994\impliedby \textit{year 0, starting point}\\
t=0\qquad P=182
\end{cases}\implies 182=ae^{k0}
\\\\\\
182=a\cdot e^0\implies 182=a\cdot 1\implies 182=a
\\\\\\
thus\qquad P=182e^{kt}\\\\
-------------------------------\\\\$

$\bf P=182e^{kt}\qquad 
\begin{cases}
2002\impliedby \textit{8 years later}\\
t=8\qquad P=186
\end{cases}\implies 186=182e^{k8}
\\\\\\
\cfrac{186}{182}=e^{8k}\implies ln\left( \frac{93}{91} \right)=ln(e^{8k})\implies ln\left( \frac{93}{91} \right)=8k
\\\\\\
\cfrac{ln\left( \frac{93}{91} \right)}{8}=k\implies 0.0027\approx k\implies \boxed{P=182e^{0.0027t}}$

what's the population in 2004? well, from 1994 to 2004 is 10 years later, so t = 10

plug that in, to get P for 2004

seropon [69]

Answer:

4.5 and -1.1 are rational numbers, -6 is an integer, and 12 is a whole number.

Step-by-step explanation:

<u>Numbers:</u>

4.5,-6,12,-1.1

<u>Let's see which option is correct:</u>

-1.1 is a rational number, 4.5 and -6 are integers, and 12 is a whole number.

4.5 in not an integer, it is incorrect

-1.1 and -6 are rational numbers, 12 is an integer, and 4.5 is a whole number.

4.5 is not a whole number, this is incorrect

4.5 and -1.1 are rational numbers, -6 is an integer, and 12 is a whole number.

Correct

12 is a rational number, -1.1 and -6 are integers, and 4.5 is a whole number.

-1.1 is not and integer, 4.5 is not a whole number, this is incorrect
