r=3.19 km
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.
Answer:
-7
Step-by-step explanation: an easy way to find the y-intercept (the point at which the line crosses the y axis) is by identifying what part of the equation does not have an x value. in this problem, it would be -7. if it were to not have a number that is followed by an x the y-intercept is 0.
hope that helps!
