Answer:
The constant of proportionality is 6
Step-by-step explanation:
Recall the equation for direct variation is 
where 
varies directly with 
and 
is the constant of proportionality. If we take any listed coordinate point, we can determine the value of . I will use (20,120) as an example:
Therefore, the constant of proportionality is 6
Answer:
35.3 ft (nearest tenth)
Step-by-step explanation:
Please see the attached picture for the full solution.
Replacing 9 for the nth term of the sequence we get 9^2 + 1 = 82, Therefore the 9th term is = 82
