I got F^-1(x) = x/4 + 4/9.
I believe the answer is B.
First, let's calculate the horizontal and vertical components of the wind speed (W) and the airplane speed (A), knowing that south is a bearing of 270° and northeast is a bearing of 45°:


Now, let's add the components of the same direction:

To find the resultant bearing (theta), we can use the formula below:

The angle -86° is equivalent to -86 + 360 = 274°.
Therefore the correct option is b.
I hope this helps you
Area=1/2.b.c.sinA
Area =1/2.4.3.0,99
Area =5,98
Answer: b=2
Step-by-step explanation:
-2+2=0
So, b would be 2 because -2 plus 2 equals zero
