worty [1.4K]

Answer: 65.1 (mg)

Step-by-step explanation:

$y=190*e^{-a*t}\\\\Calculate\ a:\\\\t=33,y=95(mg)\\\\190*e^{-a*33}=95\\\\e^{-a*33}=0.5\\\\-a*33=ln(0.5)\\\\a=\dfrac{ln(\dfrac{1}{2}) }{-33} \\\\a=0,02100... \approx{0.021}\\\\If\ t=51\ h, y=190*e^{-0.02100*51}=65.09167...\approx{65.1}$

A town has a population of 13000 and grows at 2.5% every year. What will be the population after 5 years, to the nearest whole n

vova2212 [387]

Answer:

The population will be 14708

Step-by-step explanation:

formula

A = P (1+r)^t

Initial population = P = 13000

Growth rate = r = 2.5% = 0.025

Number of years = t = 5 years.

A = 13000 (1+.025)^5 = 14708
