Answer:
Step-by-step explanation:
The first step to solving this problem is verifying if this sequence is an arithmetic sequence or a geometric sequence.
This sequence is arithmetic if:
We have that:
This is not an arithmetic sequence.
This sequence is geometric if:
This is a geometric sequence, in which:
The first term is 40, so
The common ratio is , so .
We have that:
The 10th term is . So:
Simplifying by 4, we have:
Sin(theeta) = square root(3)/2
theeta = sin inverse [square root (3)/2]
theeta = 60 degrees
as seen from trignometric table
Answer:
When two variables are directly or indirectly proportional to each other, then their relationship can be described as y = kx or y = k/x, where k determines how the two variables are related to one another.
Step-by-step explanation:
This k is known as the constant of proportionality.
