Answer:

Step-by-step explanation:
Given that,
An airthmetic sequence,
261,256,251
We need to find the 50th term.
We have,
first term, a = 261
common difference = 256-261 = -5
The nth term of the AP is given by :

So, the 50th term of the sequence is 16.
Answer:
c(x) = ($12) / x
Step-by-step explanation:
The general formula for inverse proportion is y = k/x.
In this specific problem, y represents the cost per person, k the dailyl cost ($12), and x the number of perople riding.
Then
c(x) = cost per person as a function of the number of people riding
= ($12) / x
Note that if only one person rides, that person pays $12/1, or $12; if two people, $12/2, or $6 per person, and so on.
Answer:
4.5 cm
Step-by-step explanation:
KL = LM as triangle is isosceles
LM = KM as LF = FM = KN = NM, so the triangle is equilateral
EF ║ NM as LE⊥EF and LN⊥NM
EF is half the midsegment as ∠KLN ≅ ∠MLN, and LN is angle bisector of ∠KLM
Midsegment is half the side length, and all sides are 18 cm.
EF = 1/2(1/2*18) = 4.5 cm
I think it would be (3, 8) because you look at the lowest and highest point on the y-axis. There's no infinity since the function is discrete (no arrows. it ends at a specific place). I hope this helps
1/4 is just 1 quarter of your number in this case 6.
a quarter of a foot is 3.
6 * 12 = 72 so 72 inches.
EDIT: 72 + 3 = 75
