a population of size 2000 at time t equals​0, where t is measured in years. 1. Suppose Jonesville​'s population grows by 170 peo
galina1969 [7]

Answer:

1. a_n=a_1+(n-1)d

2.a_n =a_n_-_1+a_n_-_1(0.07)

Step-by-step explanation:

For case 2 the population grows by 170 per year. Therefore for year t=0 its 2000 and t=1 then the population is 2170 and t=2 population is 2340. We can express the sequence as:

a_n=a_1+(n-1)d

We know the difference is d=170 and n=1,2,3....:

Case two can be define by:

a_n

=a_n_-_1+a_n_-_1(0.07)

Tristan is 22 years younger than Sydney. 8 years ago, Sydney's age was 2 times Tristan's age. How old is Tristan now?
Serjik [45]

Answer:

Sydney is 52 years old, and Tristan is 30.

Step-by-step explanation:

Represent Tristan's age by t and Sydney's by s.

Then s - 8 = 2(t - 8), and t = s - 22

Substituting s - 22 in the first equation, we get:

s - 8 = 2(s - 22 - 8), or

s - 8 = 2s - 60

Solving for s:  -2s + s = -60 + 8, or -s = -52.

Sydney is 52 years old, and Tristan is 30.
