Answer:
summation
Step-by-step explanation:
This symbol is the summation symbol
It means to sum what comes after it
Replace the CIRCLES by A and the SQUARES by B:
1) A + B = 14 And
2) A - B = 2
Add 1) + 2)
A+B =14
A-B = 2
------ ----
2A+0 = 16 then A = 16/2 = 8. If A = 8, then B = 6
So the CIRCLE = 8 and the SQUARE = 6
Day 1 - 100
Day 2 - 50
Day 3 - 25
Day 4 - 15
Day 5 - 10
Day 6 - 5
Day 7 - 2.5
Answer:
125
Step-by-step explanation:
f(1)= the first time (32,000)
n= 9
r= .5 (each term is being mulitplied by .5 to get the next one
We have
32,000*(.5)^(9-1)
32,000*(.5)^8
=125
