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.

C. Do Not Resuscitate.
Performing CPR to revive a patient with DNR record is both an ethical and legal dilemma. Ethically, it is necessarily expected from health care workers to perform and provide life prolonging or saving responses. However, the patient has the right to choose whether he or she should receive treatment and which must be respected. DNR order can be documented through the personal expression of the patient of refusal of treatment in front of witnesses. When the patient is incapacitated or does not have the right mind to make the decision, another way a DNR order can be obtained and documented is through the a legal guardian, legal spouse, adult child, parent, adult sibling or nearest adult relative.
