Answer:
-0.25
Step-by-step explanation:
F(m) = 2.5 + 0.12m
if Natalie paid $6.82
6.82 = 2.5 + 0.12m
0.12m = 6.82 - 2.5
0.12m = 4.32
m = 4.32 ÷ 0.12
m = 36
The call was 36 minutes long.
Quadrant number 3

Answer:
Correct answer is third from the top an = 27 · (1/3)∧(n-1)
Step-by-step explanation:
Given geometric sequence : 27, 9, 3, 1,....
First term a1= 27, second term a2= 9, third term a3= 3 etc...
Standard form of the n-th term is
an = a1 · q∧(n-1)
We will find quotient when we divide second term with first and third with second
q = a2/a1 = a3/a2 = 9/27 = 3/9 = 1/3
Formula fot n-th term is
an = 27 · (1/3)∧(n-1)
God with you!!!
