Answer:
207m
Step-by-step explanation:
We apply the cosine rule to find the distance between the other two subs.
Let this distance be x, then the cosine rule gives:
We simplify to get:
Simplify
Take square root;
To the nearest meter the distance between them is 207m
Answer: Choice D)
This is because the smallest y can get is y = 0, while the largest it can get is y = 5. It can be anything in between these y values as well.
Visually, we look for the lowest and highest points. The range is the set of all possible y outputs. In contrast, the domain is the set of all allowed x inputs.
