Step-by-step explanation:
Answer:
<em>It will take 9 years for the population to double</em>
Step-by-step explanation:
<u>Exponential Growth
</u>
The natural growth of some magnitudes can be modeled by the equation:
![P=P_o(1+r)^t](https://tex.z-dn.net/?f=P%3DP_o%281%2Br%29%5Et)
Where P is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.
The population of a city grows at a rate of r=8% = 0.08 per year. We are required to find when (t) the population will double, or P=2Po.
Substituting in the equation:
![2P_o=P_o(1+0.08)^t](https://tex.z-dn.net/?f=2P_o%3DP_o%281%2B0.08%29%5Et)
Simplifying:
![2=(1.08)^t](https://tex.z-dn.net/?f=2%3D%281.08%29%5Et)
Taking logarithms:
![\log 2=\log (1.08)^t](https://tex.z-dn.net/?f=%5Clog%202%3D%5Clog%20%281.08%29%5Et)
Applying the exponent property of logs:
![\log 2=t\log (1.08)](https://tex.z-dn.net/?f=%5Clog%202%3Dt%5Clog%20%281.08%29)
Solving for t:
![\displaystyle t=\frac{\log 2}{\log (1.08)}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20t%3D%5Cfrac%7B%5Clog%202%7D%7B%5Clog%20%281.08%29%7D)
Calculating:
![t\approx 9](https://tex.z-dn.net/?f=t%5Capprox%209)
It will take 9 years for the population to double
Answer: 61.6
Step-by-step explanation:
Use a calculator if you search it up and plug in the number it’ll give you the answers
There are 10 sides becuase the equation set up is
and equal it to 144.
Solve for n and get 10
