Answer:
<em>See the graph with both lines attached</em>
A) From the tables we see the constant change of values in the second column and the initial value is zero.
This represents a proportional relationship for both tables.
B) <u>Revel</u>
- Rate of change is 5 per hour, the equation is:
- y = 5x, where y is cost, x - is the number of hours
<u>Scooters</u>
- Rate of change is 6 per hour, the equation is:
- y = 6x, where y is cost, x - is the number of hours
C) <u>When x = 12</u>,
- y = 5*12 = $60 for Revel
- y = 6*12 = $72 for Scooters
D) <u>The point (4, 24) represents that:</u>
- The cost of 4 hours is $24
E) The second table has confusing titles (days and number of cell phones) but if we assume its same as the first table, then Revel has lower rate as 5 < 6.
Comparing the prices and the graph, Revel has better rate per hour.
The equivalent expression of 14r^4y^6/7r^8y^2 is 2y^4/r^4
<h3>How to determine the equivalent function?</h3>
The expression is given as:
14r^4y^6/7r^8y^2
Start by dividing 14 by 7
2r^4y^6/r^8y^2
Next divide y^6 by y^2
2r^4y^4/r^8
Lastly divide r^4 by r^8
2y^4/r^4
Hence, the equivalent expression of 14r^4y^6/7r^8y^2 is 2y^4/r^4

Step-by-step explanation:
Alright, lets get started.
Please refer the diagram I have attached.
The width of the room is 30 meters.
If two beams will be making an angle, they will half the width.
There will be a right triangle made, so using SOH CAH TOA,
taking cos inverse
