Answer:
The correct option is A.
Step-by-step explanation:
The general exponential growth model is defined as
![f(x)=a(1+r)^x](https://tex.z-dn.net/?f=f%28x%29%3Da%281%2Br%29%5Ex)
Where, a is initial value, r is growth rate and x is time.
The initial population of town is 9800 and growth rate is 2%. The population growth model is defined as
![f(x)=9800(1+\frac{2}{100})^x](https://tex.z-dn.net/?f=f%28x%29%3D9800%281%2B%5Cfrac%7B2%7D%7B100%7D%29%5Ex)
![f(x)=9800(1+0.02)^x](https://tex.z-dn.net/?f=f%28x%29%3D9800%281%2B0.02%29%5Ex)
![f(x)=9800(1.02)^x](https://tex.z-dn.net/?f=f%28x%29%3D9800%281.02%29%5Ex)
Put x=7 to find the estimated population after 7 years.
![f(x)=9800(1.02)^7](https://tex.z-dn.net/?f=f%28x%29%3D9800%281.02%29%5E7)
![f(x)=11257.119543\approx 11257](https://tex.z-dn.net/?f=f%28x%29%3D11257.119543%5Capprox%2011257)
Therefore the correct option is A.
Step-by-step explanation:
(x - 3)2 = 5
2x - 6 = 5
2x = 5 +6
2x = 11
x = 11/2
x = 5.5
Answer:
153.86
Step-by-step explanation:
To find the area of a circle, we use the formula
.
d=14
r=d/2
r=7
![(3.14)(7^{2} )](https://tex.z-dn.net/?f=%283.14%29%287%5E%7B2%7D%20%29)
153.86
