Answer:
The correct option is;
5.89°
Step-by-step explanation:
The speed with which the plane flies = 350 mph
The direction of flight of the plane = N 40° E
The speed with which the wind blows = 40 mph
The direction in which the wind blows = S 70° E
Therefore, we have;
The resolution of the components of the motion of the plane, given as follows;
= 350 × sin(40°)·i + 350 × cos(40°)·j
The resolution of the components of the motion of the wind, given as follows;
= 40 × sin(70°)·i - 40 × cos(70°)·j
The resultant motion of the plane is given as follows;
= 262.563·i + 254.435·j
The direction of motion of the plane = tan⁻¹(262.563/254.435) ≈ N 45.9° E
Therefore, the plane's drift = Plane's Track - Plane's Heading = N 45.9° E - N 40° E ≈ 5.9° ≈ 5.89°
Therefore, the correct option is 5.89°.
Answer:
10.14 feet per year.
Step-by-step explanation:
Given:
Over the next 3 1/2 years, a tree grew to a final height of 35 1/2 feet.
Question asked:
During those 3 1/2 years, what was the average yearly growth rate of the height of the tree?
Solution:
We can find the average yearly growth rate by using average formula, taking
final height of the tree as sum of observation and time span taken to growth as number of observation:-
As we know:
Thus, during , the average yearly growth rate of the height of the tree was 10.14 feet per year
