To figure out which airline provides more reliable service, we need to figure out what ABC Airlines's delays are in percents.
To get that, we need to reduce 18/126 by 2.
When we reduce both the numerator and the denominator we get 9/63.
Now, we cannot reduce that again, without getting a decimal for the numerator/denominator.
So, now that we know that the fraction is 9/63, we divide it, and we get :
<span> 0.142857
</span>
Changing that into a percent, we get 14%.
14% is the percent that ABC Airlines has delays.
DEF Airlines has delays of 13% in recent flights.
So, from that, we can conclude that DEF gives more reliable service.
Answer:
d. parabola, 0°
Step-by-step explanation:
y² + 8x - 0
y² = -8x
Where x = cos t , y = sin t
Sin² t = -8 Cos t
1 - Cos² t = -8 Cos t
- Cos² t + 8 Cos t + 1 = 0
t = 2лπ ± (3 + √10) , л∈Z
Angle of rotation
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:
Draw a diagram with rectangle where 10" is the diagonal, 6" is the bottom of the screen, then you have a right triangle with hypotenuse of 10 and one side = 6.
Use Pythagorean theorm to find unknown side x;
x2 + 62 = 102 Solving for x, you get X = 8 inches
