Rabbit's position vector (r) in the unit vector is 203.5î - 57j and the magnitude and directional angle of vector (r) are 195.35m and 0.004° respectively.
Given
x = 0.3t² + 7.2t + 28
y = 0.22t² - 9.1t +30
At t = 15s
x = 0.3(15)² + 7.2(15) +28 = 203.5
y = 0.22(15)² - 9.1(15) + 30 = -57
The rabbit's position vector (r) in unit vector notation is:
r = 203.5î - 57j
The magnitude of position vector (r)
r = √x² + y²
r = √(203.5)² - (57)² =√38163.25
= 195.35m
The directional angle of position vector (r)
tanθ = y/x = -57/203.5
θ = 
(-57/203.5)
θ = 0.004°
Hence, rabbit's position vector (r) in the unit vector is 203.5î - 57j and the magnitude and directional angle of vector (r) are 195.35m and 0.004° respectively.

Answer:
Market-oriented changes, competition, and privately organized managed care programs
Explanation:
Problems related to the national health system have been reported for decades. Many people complain that there is a great difficulty regarding the use of medical services due to the imbalance between cost, quality and access to medical care. These problems have been a recurring agenda in government campaigns, as many candidates for political office have used medical care to make campaign promises and to establish competition with other governments, and these problems have generated some competition between the government. and the private sectors. An example of this happened in the 1990s, where problems with health care systems generated competition between the government and the private sectors. This competition was characterized by market-driven changes, competition, and privately managed managed care programs.
