Answer:
8.4 * 10^6
Step-by-step explanation:
8.4 * 10^6
1 million = 1 * 10^6
8 million 4 hundred thousand is 8.4 * 10^4 because this number is 8.4 times bigger than a million.
=[(sinx/cosx)/(1+1/cosx)] + [(1+1/cosx)/(sinx/cosx)]
=[(sinx/cosx)/(cosx+1/cosx)]+[(cosx+1/cosx)/(sinx/cosx)]
= [sinx/(cosx+1)] + [(cosx+1)/sinx]
= [sin^2x+(cosx+1)^2] / [sinx (cosx+1)]
= [2+2cosx] / [sinx(cosx+1)]
=[2(cosx+1)] / [sinx (cosx+1)]
= 2/sinx
= 2 cscx

Answer:
![L=3.999 \: dm](https://tex.z-dn.net/?f=L%3D3.999%20%5C%3A%20dm)
![A=183.4581\:dm^{2}](https://tex.z-dn.net/?f=A%3D183.4581%5C%3Adm%5E%7B2%7D)
Step-by-step explanation:
La relación del apotema y el lado de un dodecágono regular está dada por la siguiente ecuación:
![a_{p}=L\frac{2+\sqrt{3}}{2}](https://tex.z-dn.net/?f=a_%7Bp%7D%3DL%5Cfrac%7B2%2B%5Csqrt%7B3%7D%7D%7B2%7D)
Sabiendo que la apotema es 7.464 el lado sera:
![L=\frac{2*a_{p}}{2+\sqrt{3}}](https://tex.z-dn.net/?f=L%3D%5Cfrac%7B2%2Aa_%7Bp%7D%7D%7B2%2B%5Csqrt%7B3%7D%7D)
![L=\frac{2*7.464}{2+\sqrt{3}}](https://tex.z-dn.net/?f=L%3D%5Cfrac%7B2%2A7.464%7D%7B2%2B%5Csqrt%7B3%7D%7D)
![L=3.999 \: dm](https://tex.z-dn.net/?f=L%3D3.999%20%5C%3A%20dm)
Por otro lado el area de un dodecágono regular esta dada por:
![A=6a_{p}L](https://tex.z-dn.net/?f=A%3D6a_%7Bp%7DL)
![A=6*7.646*3.999](https://tex.z-dn.net/?f=A%3D6%2A7.646%2A3.999)
![A=183.4581\:dm^{2}](https://tex.z-dn.net/?f=A%3D183.4581%5C%3Adm%5E%7B2%7D)

Answer:
87.35%
Explanation:
If the total is 1,032,471, it equals 100%
African Americans are in 901,896
1,032,471=100
901,896 = X
Cross multiply
1,032,471x=90,189,600
Divide
x= 87.35%
Hope you get it!
