Answer:
According to the map, the length of the canal is 16.4 centimeters.
Step-by-step explanation:
If the real length of Panama Canal = 20 kilometers
and the canal's length on the map = 4 centimeters
Then, the scale factor is 
= 
= 
If the actual length of the Panama Canal = 82 kilometers
The length of the canal on the map = Actual length × Scale factor
= 
= 16.4 centimeters
So, the canal's length on the map is 16.4 centimeters.
It is not possible, as there are just 2 sides, and they likely flipped it in various ways. They experienced some 'luck'.
The formula that describes the sequence is 
Step-by-step explanation:
The nth-term formula for a geometric sequence is
, where
- a represents the first term of the sequence
- r signifies the common ratio between any two consecutive terms
= 
∵ The sequence is
, -4, -24, -144,.......
∵ The first term is 
∵ The second term is -4
∴ 
∵ The third term is -24
∴ 
∵ The fourth term is -144
∴ 
∵
=
=
= 6
∴ There is a consistent ratio between two consecutive terms
∴ The sequence qualifies as a geometric sequence
∵ The formula for the nth term of the geometric sequence is 
∵ a = 
∵ r = 6
∴ The equation for the sequence is 
The formula that can be employed to outline the sequence is
