HELP PLEASE 10 POINTS!!!!!! A country's population in 1993 was 171 million. In 1999 it was 176 million. Estimate the population

in 2012 using the exponential growth formula. Round your answer to the nearest million. P=Ae^kt This is exponential growth

Let 1993 = time 0 = 0.  

Let 1999 = time 6 = 6  

Let 2012 = time 19 = 19  

So, a = 171 (million). First solve for k.  

176 = 171 e^k6  

176/171 = e^(k*6)  

ln (176/171) = 6k  

k = 1/6 ln (176/171)  

So, in 2012 we have: P(19) = 171 e^(19k), where k = 1/6 ln (176/171)


Hope this helped!

Simplify the expression. (3.14×107)×(1.3×10−3)÷0.2<br> Scientific notation PLS!
marusya05 [52]

3.14 \times 107 = 335.98
(335.98) \times (1.3 \times 10 - 3) \div 0.2
1.3 \times 10 = 13 - 3 = 10
(335.98) \times (10) \div 0.2
335.98 \times 10 = 3359.8
3359.8  \div 0.2 = 16799
1.6799 \times  {10}^{4}

Limit question: lim x--&gt;pi ((e^sinx)-1)/(x-pi)
aleksandr82 [10.1K]
\displaystyle\lim_{x\to\pi}\dfrac{e^{\sin x}-1}{x-\pi}

Notice that if f(x)=e^{\sin x}, then f(\pi)=e^{\sin\pi}=e^0=1. Recall the definition of the derivative of a function f(x) at a point x=c:

f'(c):=\displaystyle\lim_{x\to c}\frac{f(x)-f(c)}{x-c}

So the value of this limit is exactly the value of the derivative of f(x)=e^{\sin x} at x=\pi.

You have

f'(x)=\cos x\,e^{\sin x}\implies f'(\pi)=\cos\pi\,e^{\sin\pi}=-1
