The risk-benefit assessment is widely used in the field of medicine. Apart from being therapeutic, it is a known fact that synthetic medicines also carry side effects. However, if the healthcare provider believes that a certain medication outweighs the side effects, then he or she will prescribe the said medicine. This is the very reason why the concept of risk-benefit is truly vital.
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.

Have the person sit still with their hand resting stationery in a position below their heart. Locate their thumb and follow the Radius bone from the thumb toward their wrist. Just past their wrist use the pads of your index and middle finger to palpate the radius pulse just inside the radial bone on the distal end of the forearm. If you measure the pulse for 15 secs multiply by 4, 30 seconds multiply by 2, or measure a full minute to beats per minute. After an injury to an upper extremities, it is common to locate the radial pulse on both wrists at the same time to compare the strength of the pulse thus making sure circulation is good.
A and D both seem correct
I have a question. Where are "which of these?"
