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.

Regular body temperature for a human is 98.6 degrees. Any higher would result in a fever.
Answer:
i will try my best
Explanation:
The risk factor Of this Situation is that I can be kidnapped or get lost.
The outcome of this situation is that I will have to walk a mile after a movie and not be sure or be safe if I will make it home
What I would do to avoid danger I would do what I was taught stranger danger. Besides that I would call my friend and tell him to stay on the call until I get home so that way he knows what am I doing In case of anything he would know. After that I will keep an eye on my surroundings make sure nobody is following. Lastly In case someone is following me I would run home or be in a call with my mom.Of course to avoid all of this I would've just called a taxi.
Yes, in its entirety, because the barrier methods are natural and
protect more safely than the hormonal ones because hormonal methods can
fail due to the incidences of the body, while the barrier method
prevents conception more effective and safe.
