Answer:
The sequence is a function as for any value of n we can not get more than one different 
value.
Step-by-step explanation:
Tilly starts by running 1 mile in the first week and tripling the number of miles each week.
Now, the number of miles Tilly will run can be modeled by the sequence 
, where n is the number of weeks since she began her program.
Therefore, in the second week she runs 3 miles, in the third week she runs 9 miles and so on.
Therefore, the sequence is a function as for any value of n we can not get more than one different value. (Answer)
Answer:y+5=-3/2(x+6)
Step-by-step explanation:point slope form
Given:
To find:
The quadrant in which 
lie.
Solution:
Quadrant concept:
In Quadrant I, all trigonometric ratios are positive.
In Quadrant II, only 
and 
are positive.
In Quadrant III, only 
and 
are positive.
In Quadrant IV, only 
and 
are positive.
We have,
Here, is negative and is also negative. It is possible, if 
lies in the Quadrant IV.
Therefore, the correct option is D.
