Answer:
It would be 3/4 which is the fractional version of 0.75
additive: 1/4+ 2/3=3/4
Since a calculator is involved in finding the answer, it makes sense to me to use a calculator capable of adding vectors.
The airplane's ground speed is 158 mph, and its heading is 205.3°.

A diagram can be helpful. You have enough information to determine two sides of a triangle and the angle between them. This makes using the Law of Cosines feasible for determining the resultant (r) of adding the two vectors.
.. r^2 = 165^2 +15^2 -2*165*15*cos(60°) = 24975
.. r = √24975 ≈ 158.03
Then the angle β between the plane's heading and its actual direction can be found from the Law of Sines
.. β = arcsin(15/158.03*sin(60°)) = 4.7°
Thus the actual direction of the airplane is 210° -4.7° = 205.3°.
The ground speed and course of the plane are 158 mph @ 205.3°.
200.7 I hope this is the answer
This is not middle school work
Answer:
f(x) = 2x + 4
Step-by-step explanation:
This is an arithmetic sequence
y = a1 + (x - 1)d where a1 = first term and d = common difference so it is
y = 6 + (x - 1)*2
y = 2x + 4 answer
