PLEASE HELP
1) What is the common ratio of the following geometric series?
5, 25, 125...
A) r =25
B)r =5
C)r =125
D)r =100
2) Using the explicit rule of f(n)=200(0.5), find the first 3 terms.
A) 200, 100, 50
B) 100, 50, 200
C) 40, 80, 120
D) 1, 2, 3

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

step-by-step explanation:

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"
