Answer:
- 1364
Step-by-step explanation:
The n th term of a geometric series is
= a
where a is the first term and r the common ratio
4
← is an n th term
with a = 4 and r = - 2
The sum to n terms of a geometric series is
= 
, thus
= 
= 
= 
= 
= - 1364
Answer:
51
Step-by-step explanation:
simplify the equation and you get the answer
Answer:
660 miles.
Step-by-step explanation:
385 m/7 h = 55 m/h
55 m/h * 12 h = 660 m
Here the change in x is +5 and that in y is +10 (from y= -96 to y= -86). Thus, the slope, (change in y) / (change in x) is m = 10/5, or m = 2.
Answer:
-9.8n + 10.9
Step-by-step explanation:
2.9 + 8 = 10.9
-4n + -5.8n = -9.8n
