Answer:
Step-by-step explanation:
The easiest way to tell if a relation is a function is to look at the x coordinates. If none of them are the same in the set, then the relation is a function. If any of the x values are used more than once in the set, it is only a relation. This set uses -3 two times, so it is a relation.
Answer:
26x+61
Step-by-step explanation:
Multiply both sides by 19 to get w=171
Answer:
55.64
Step-by-step explanation:
The range finder is 92 feet from the building and 106 feet from the top of the building i.e. hypotheses
We will use the Pythagorean theorem:
x^2 = 106^2 - 92^2
= 11,236 - 8,464
= 2,772
= √2,772
x =
52.64978632
The height of the building:
h = x + 3
= 52.64978632
+ 3
= 55.64978632
or
≈ 55.64 feet
