Answer:
⁵/₃
Step-by-step explanation:
If you are at the foot of the guy wire, the wire is going <em>up</em>.
Slope = Δy/Δx = 25/15 = ⁵/₃
If you are at the top of the pole, the wire is going <em>down</em>.
Slope = Δy/Δx = -25/15 = -⁵/₃
9 miles every week + 15 miles every weekend = 24 miles every 7 days =
24/7 = 3 3/7 miles per day
The answer is 120 sections.
Here's an explanation:
The rope is 105 feet long, and each section needs to be 7/8 feet. So to find the number of sections, you need to divide 105 by 7/8. 105 divided by 7/8 gives you the quotient 120. So there are 120 sections.
Given:
The function that represents how the amount of fuel changes as a function of distance flown is

where x represents miles flown, and f(x) represents the amount of fuel remaining.
To find:
The rate of change for this scenario.
Solution:
The slope intercept form of a linear function is
...(i)
Where, m is the slope or rate of change and b is the y-intercept.
We have,
...(ii)
On comparing (i) and (ii), we get

Therefore, the rate of change for this scenario is -0.9. It means, the amount of fuel in the airplane is decreasing by 0.9 gallons per mile.
