Answer:
By allowing a long period of time to pass
Step-by-step explanation:
f(n) = -6.5n + 14.5
&
f(1) = 8, f(n+1) = f(n) - 6.5
7/8 = 87.5%
I'm guessing it is meant to say round to the nearest 10th of a percent
If the question actually says something different comment so i can fix it
First you need to change 45 feet to 540 inches.
Now you can compare the two ratios:
1 : 25 and 25 : 540
We now need to change the second ratio to a unit rate:
25:540 as a unit rate would be 1 : 21.6 and this is steeper than the a 1 : 25 drop
So, your answer would be: pipe drops to much vertically to function properly
Answer by JKismyhusbandbae: -12 ≤ f ≤ 6
-3f - 9|-8+8 ≤ 19 + 8
|-3f-9|≤ 27
-3f-9≤ 27 and -3f - 9≥ 27
-3f-9+9≤27+9
-3f ≤ 36
(-3f) (-1) ≥ 36 (-1)3f ≥ - 36
≥ 
f ≥ - 12-3f
-9+9≥-27+9
-3f≥-18
≤ 
F ≤ 6
