Answer:
Are you asking how the answer became 16.1?
Step-by-step explanation:
Well the squiggly lines indicate that its an approximation so use a scientific calculator if you have one or use an online scientific calculator and plug in 12sin89/sin48. Your answer should be 16.145 rounded to 16.1

A: What do the x-intercepts and maximum value of the graph represent?
There are two x-intercepts: x = 0 and x = 36
Those values are the points at which the height of the tunnel is 0.
That means that the width of the tunnel at the ground level is 36 - 0 = 36.
The maximum value of the graph is 32, at x= 18. That, represents that at the center, x= 18, the tunnel has a height of 32.
What are the intervals where the function is increasing and decreasing,
and what do they represent about the distance and height? (6 points)
The interval where the function is increasing is (0,18) and the interval where teh function is decreasing is (18,36)
That represents that the height starts to increase with the distance (from 0 to 18) reaches a maximum of 32, at x = 18, and starts to decrease with the distance until x = 36.
Part B: What is an approximate average rate of change of the graph from x
= 5 to x = 15, and what does this rate represent? (4 points)
The average rate of change from x = 5 to x = 15 is the change in height divided by the change in distance
=> average rate of change = Δy / Δx
Δy ≈ 31 -14 = 17
Δx = 15 - 5 = 10
=> Δy / Δx ≈ 17 / 10 = 1.7

Anyway
so the recursive rule tells the relationship between the previous term and the term we want to find
given
an=2n+11
it is clear that the first term is 13
2nd term is 15
3rd term is 17
each term increases by 2
so
a term is equal to the previous term plus 2
an=a(n-1)+2
the first one is the answer
I think u combined like terms , like 11+44 which is 55 then your answer is 55-3x or -3x+55 , im not really sure , hope this helps.
