Answer:
$1.29
Step-by-step explanation:
5.16 divided by 4
Between 1994 and 1998 the population increased by 5 miliion, approximately 1 1/4 million a year.
2016 - 1998 = 18 years at 1 1/4 million a year = 22 1/2 million
Estimate therefore is: 81 + 22 1/2 = 103 !/2 million
The correct answer is 8800
From the de Moivre's we have,
<span>
(cosθ+isinθ)^n=cos(nθ)+isin(nθ)

Therefore,
</span><span>
R((cosθ+isinθ)^5)=cos(5θ)I((cosθ+isinθ)^5)=sin(5θ)
</span><span>
Simplifying,

cos^5(θ)−10(sin^2(θ))(cos^3(θ))+5(sin^4(θ))(cosθ)=cos(5θ) </span><span>
