Answer:
1. 
2.
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:
We know the difference is d=170 and n=1,2,3....:
Case two can be define by:
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.
Answer:
-279
Step-by-step explanation:
a=64
d=t2-t1=57-64=-7
t50=a+49d=64+49×(-7)
=64-343
=-279
