The rumor is spreading to a double amount of people each time and started with only one person.
On the first day, two people knew it. 2¹ = 2
On the second day, four people knew it. 2² = 4
On the third day, eight people knew it. 2³ = 8
On the nth day, the people that will know it = 2ⁿ
Thus, on the eighth day: 2⁸ = 256 people will know it
The board is 12x larger in length than the nails. (Since the width of the board and nails are unknown, I am assuming you mean the length, not area difference)
Answer:
Option a.
I and III
Step-by-step explanation:
Observing the graph
For n=400 coats
The cost is about $2,200
and
The revenue is less than $1,400
Substitute the value of n=400 in each equation to find the solution
I Cost 1.5(400)+1,600=$2,200 ----> is ok
II Cost 4.5(400)+1,600=$3,400 ----> is not ok ( is greater than $2,200)
III Revenue 3.25(400)=$1,300 ----> is ok ( is less than $1,400)
IV Revenue 5.75(400)=$2,300 ----> is not ok ( is greater than $1,400)
therefore
The solution is I and III

Answer:
1) 12
2) c=-25
3) x = -16 2/3
Step-by-step explanation:
1) ..........................
- 6*(4-10+8) =
- 6*(- 6+8) =
- 6*2=
- 12
2) ..........................
- 34 + 2c = -16
- 2c = - 16 -34
- 2c = -50
- c = -50/2
- c=-25
3) ..........................
- 40 = -3x - 10
- 40+ 10 = -3x
- -3x = 50
- x = 50/-3
- x=-16 2/3
