Answer:
b) 2.45
Step-by-step explanation:
The Euclidean distance in 3-space is the root of the sum of the squares of the x-, y-, and z-differences between the points.
<h3>Application</h3>
For the given points ...

The distance between x and y is ...

24h + 18f = 88.50
28h + 9f = 88.25.....multiply by -2
---------------------
24h + 18f = 88.50
-56h - 18f = - 176.50 (result of multiplying by -2)
--------------------add
-32h = - 88
h = -88/-32
h = 2.75 <===
Given the cost of $28 to rent a trailer for an x amount of hours:
The expression is 28x
We are given the angle WON. The letters W, O and N represents points included in the angle. One of these points is the vertex of the angle. It is the point which an angle is measured. For this case, the vertex is point O.
Attendance with the higher ticket price is ...
... $1750/$7 = 250
So the percentage change in attendance is ...
... change = (new - original)/original × 100%
... = (250 -300)/300 × 100% = -1/6×100% ≈ -17%
