The initial population of atown is 3500 and it grows with a doubling time of 12 years. Determine how long it will take for the p
opulation to quadruple.
1 answer:
After 12 years
3500 * 2 = 7000
after 24 years
7000 * 2 = 14000
14000 : 3500 = 4
so the answer is 24 years

Answer:
![\sqrt[3]{a^{2}+b^{2}}=(a^{2}+b^{2})^{\frac{1}{3}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Ba%5E%7B2%7D%2Bb%5E%7B2%7D%7D%3D%28a%5E%7B2%7D%2Bb%5E%7B2%7D%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D)
Step-by-step explanation:
∵∛x = (x)^1/3
∴ ![\sqrt[3]{a^{2}+b^{2}}=(a^{2}+b^{2})^{\frac{1}{3}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Ba%5E%7B2%7D%2Bb%5E%7B2%7D%7D%3D%28a%5E%7B2%7D%2Bb%5E%7B2%7D%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D)
So you can replace the radicals by fractional exponents
Yes they are proportionate
54/99 simplified is:
54/99= 6/11
The answer is 6/11
-3(6)-2-(-4(6)+10)
-3(6)-2-(-24+10)
-18-2--14
answer is -6
You did it right because 12 x 2 = 24 x 8 = 192
