Answer:
First table
Step-by-step explanation:
We have to find the set of value which could be from a direct proportion.
We know that
Direct proportion :
When x is directly proportional to y
Where k=Proportionality constant
K remain constant when x and y are in direct proportion
From first table
When x and y are both varies then ratio of x and y remain constant.Hence, it is in direct proportion.
From second table
not ]define
It is not direct proportion because k does not remain constant.
From third table
It is not direct proportion because k does not remain constant.
Answer:
x = 225.16 feet
Step-by-step explanation:
Given that,
The angle between the piling and the pier is 60°.
A surveyor has set up his transit on one side of the lake 130 feet from a piling that is directly across from a pier on the other side of the lake.
We need to find the distance between the piling and the pier. Let the distance be d. Using the trigonometry to find it as follows :
So, the required distance is 225.16 feet.
