Answer:
18.559 km/min
Step-by-step explanation:
Horizontal and vertical velocities of the plane:
Vx = 19*cos(35) = 15.5639
Vy = 19*sin(35) = 10.898
Location of plane after 3 minutes will be:
X-component = Vx * 2 = 15.5639 * 2 = 31.1278 km
Y-component = 12 + (Vy * 2) = 12 + (10.898 * 2) = 33.796 km
Angle to the radar station (measured relative to ground) will be given as;
Angle = tan^(-1) (Y-component/X-component) = tan^(-1) (33.796/31.1278) = 47.35°
Thus;
Velocity component along the line between the radar and the plane:
Vt = 19 * cos (47.3534° - 35°)
Vt = 19 * cos 12.3534
Vt = 19 * 0.9768
Vt = 18.559 km/min
Answer:
A) 5 units
Step-by-step explanation:
ABC is a 30-69-90 degree triangle whose sides, respectively, are in the ratio of 1 : : 2
so if the hypotenuse is 10, the side opposite the 30° angle is half of that, or 5
Yes, it can be a parallelogram. This is because both sides are parallel.
Answer:
im very confuesed but i think you should cut it into peices and take it slow and steady. You got this!~
