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.

It would take<u> 125 minutes</u> to infuse the ns if the set delivers 10 gtt/ml. By taking the following factors into account: - The volume should be given in milliliters. - Time is expressed in minutes or hours. - Adjust the drop factor in gtts/ml.
Given, 500 ml of ns:
10 x 500 = 5,000 drops
10 drops per milliliter is 10 gtt/mL.
So, for 500 mL, you will receive:
Given that the flow rate is 40 gtt/min,
or 40 drops each minute,
we may calculate the number of minutes by dividing the total drops by 40:
5,000/40 = 125 minutes
How can I ensure that the infusion is administered at the prescribed rate?
If a provider orders an intravenous fluid infusion, this health app can assist you in ensuring that the fluid administered is given at the prescribed rate.
