The least common multiple of 3, 4, 6, and 8 is A. 24. B. 96. C. 72. D. 8.

garri49 [273]

Try the lowest option first. 8 is not divisible by 3 so you can rule out D. The next lowest option is 24. 24 is divisible by all 4 numbers so that it is the answer.

At this point this one decides my grade

Tresset [83]

Answer:

A = 16π cm²

Step-by-step explanation:

We require to find the radius r

Given circumference C = 8π , then

2πr = 8π ( divide both sides by 2π )

r = 4 , then

A = πr² = π × 4² = 16π cm²

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
