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:
n = 5/2
Step-by-step explanation:
Add all of the sides up to make an equation
(5n - 6) + n + (2n + 1) = 15
8n -5 = 15
8n = 20
n = 5/2
Step-by-step explanation:
Area = length×breath
=18×11
=198cm²

The correct property of the quadratic parent function is given by:
B. Its vertex is at the origin.
<h3>What is the quadratic parent function?</h3>
The quadratic parent function is modeled by:
y = x².
It has the vertex at the origin and increases to the left and to the right, into quadrants I and II, forming a function that is graphed by a parabola.
Hence the correct option regarding a property of the quadratic parent function is given by:
B. Its vertex is at the origin.
