The scale from a map to actual distance is 2.5 cm to 620 mi. The distance on the map between Chicago and Boston is about 3.5 cm.
1 answer:
Answer: 868 miles
Step-by-step explanation:
Given: The scale from a map to actual distance is 2.5 cm to 620 miles.
i.e. 1 cm on map =
If the distance on the map between Chicago and Boston is about 3.5 cm.
Then, the actual distance between them =
Hence, the approximate distance between Chicago and Boston = 868 miles.

Answer:
Step-by-step explanation:
The recursive rule is a term defined in terms of other terms in the sequence.
The is a geometric sequence because it has a common ratio.
The common ratio can be found by dividing a term by previous term.
For example, all of these are equal:
They are all equal to .
So we are saying:
More formally:
.
Multiply both sides by :
When doing recursive form, you need to state a term of the sequence (or more depending on the recursive form you have).
So the first term is 2.
So the full thing for the answer is:
