Answer:
vr = 
vp = 486.22 j + 205.9 j
Theta 
Step-by-step explanation:
The resultant velocity vr = vp + vw
vp = vector velocity of plane and
vw = vector velocity of wind
vr = vector resultant velocity
in one hour the plane travels 540 miles and hence the speed is 540 mph
Hence vr =
vp = 486.22 j + 205.9 j
Theta
The dot product is a technique that solves the resultant vector through the use of matrices. Since we have no coordinates, we can't use matrices. However, we can still solve the resultant vector (red line) through cosine law. The solution is as follows:
R² = 4² + (1/2)² - 2(4)(1/2)(cos π/4)
R = √13.42
R = 3.66
The resultant vector has a magnitude of 3.66.
Number 5 is 15.9 kilograms
And number 6 is 6 million cubic feet per minute
You just cross multiply
The answer is B because if you follow it starting from it AAS
