A. I and II
These two graphs show the same data just in different forms, bar graph and line graph.
Write a recursive rule for the sequence.
-2,0,2,4,6
STEP 1:
a1 = -2
a2 = 0
a3 = 2
STEP 2:
d = a2-(a1)=a3
= d = 0-(-2)=2
STEP 3:
An = a+(n-1)d
ANS:
First multiply 20% by 50: .2x50=10. Then subtract that from 50: 50-10=40. The new price is $40 :)
0.81 = 81/100
0.5 = 5/10 = 1/2
0.63 = 63/100
0.214 = 214/1000 = 107/500
