Answer:
3/4 of the way from A to B = 
or (-3.5, 1.25)
Step-by-step explanation:
Please see attached images below for explanation:
<span>1) if 2 times the wind speed is increased by 2, the wind speed is still less
than 46 km/h.
=> 2x + 2 < 46
2) Twice the wind speed minus 27 is greater than 11 km/h.
=> 2x - 27 > 11
Part A: Create a compound inequality to represent the wind speed range.
(3 points)
from 2x + 2 < 46
=> 2x < 44
=> x < 22
from 2x - 27 > 11
=> 2x > 11 + 27
=> 2x > 38
=> x > 19
The set of inequalities is
2x + 2 <46
2x - 27 > 11
The solution is x < 22 and x > 19, which is:
19 < x < 22 <----- answer
Part B: Can the wind speed in this town be 20 km/h? Justify
your answer by solving the inequalities in Part A. (3 points)
Yes, the wind speed can be 20 km/h, because the solution of the inequality is the range (19,22).
Part C:
The average wind speed in another town is 23 km/h, but the actual wind
speed is within 4 km/h of the average. Write and solve an inequality to
find the range of wind speed in this town.
x ≥ 23 - 4 => x ≥ 19
x ≤ 23 + 4=> x ≤ 27
=> 19 ≤ x ≤ 27
=> [19,27]

Answer:
x ≈ 23.4
Step-by-step explanation:
You are correct that the given information indicates the tangent function is appropriate.
Tan = Opposite/Adjacent
tan(59°) = 39/x
Multiply this equation by x/tan(59°) and you get ...
x = 39/tan(59°)
x ≈ 39/1.6643 ≈ 23.43
The appropriate answer choice is ...
x = 23.4
