The answer is 30. you can find the unit rate but the calculator was invented a long time ago so i used that ;)
I'm not quite sure what your asking but if you just want to represent it then it is 57+b
32x^5/7 This is the answer for that equation.
Answer:
The population will reach 20,400 after 6 years.
Step-by-step explanation:
Exponential function:

y(t)= Population after t years
= initial population
r= rate of grow
t= time.
A town has a population of 17,000 and grows at a rate 3% every year.
y(t)= 20,400,
= 17,000, r=3%=0.03, t=?



Taking ln function both sides



⇒ t = 6 year.
The population will reach 20,400 after 6 years.
