Answer:
Step-by-step explanation:
Since the amplitude of the cosine function is 2, I would put the multiply it by 2. There is no phase shift
The period is 1/2, so it would be 4pi
Plug them in into y=Acos(Bx), y=2cos(4pix)
The population of a town has approximately doubled every 17 years since 1950.
the equation P= where Po is the population of the town in 1950, is used to model the population, P, of the town t years after 1950.
When t=17 yrs
P=2
for 1 year
The equation becomes
P = -------------(1)
Our original equation is
----------------------------------(2)
equating expression 1 and 2
Cancelling from both sides we get
t/17=k
⇒k=t/17 is the solution.
