A.The city council member's claim is not valid because according to the formula, t is in years, so it has to be divided by 12 months then multiplied by 1.015
B. f(t)=120,000 (1.015)t/12 where the t is time in years is divided by 12 to get time in months
C. 507500 people
Step-by-step explanation:
Given that the population can be modeled by the formula f(t)=120,000(1.015)t , where f(t) represents the population after t years.
Based on the formula, after 1 year the population will be;
f(1)=120,000(1.015)1
=120,000*1.015
=121,800
The city council member's claim is not valid because according to the formula, t is in years, so it has to be divided by 12 months then multiplied by 1.015
B.
The formula can be modified as;
f(t)=120,000 (1.015)t/12 where the t is time in years is divided by 12 to get time in months
C.
The population after 50 months will be;
f(t)=120,000 +(1.015)t/12
f(50/12) =120,000(1.015)*50/12
=120,000(1.015) * 4.167
=507500
