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:
Well I do not think it would be A or B. The best answer I can give you is D. If you talk to someone face to face it makes the message more clear and the person will be able to understand better, plus it's another good way to give a message rather then mailing or something like that. If the answer is not D however then it would be C.

TRUE: Food that will be served immediately can be reheated to any temperature as long as the food was cooked and cooled properly. Food reheated for hot-holding must reach an internal temperature of 165℉ within two hours. The food needs to stay at this temperature for at least 15 seconds before serving.
Answer:
C
Explanation:\
The rest make no sense or would hurt him more.
A. Posting an intentionally hurtful or mean comment on someone's social media and being blocked from that account.
B. Posting photos or videos of yourself doing illegal activities (drinking while underage, doing drugs, etc.). Companies and colleges look at your social media to see what you are really like, which could lead to not being accepted into a college or being kicked out of a sports team.
