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.

The correct answer is A. Community members brainstorm ways to improve overall safety.
Explanation
A healthy family relationship is one in which each of its members seeks the physical, mental, and social well-being of themselves and the other members. In these relationships the members are mediated by assertive communication that allows them to express their ideas and thoughts freely without fear of being pointed out, on the contrary, they tend to support each other.
Additionally, healthy family relationships positively affect the community because it makes the members of a community have bonds of identity and unity among all so that they can make joint decisions in a correct and consensual manner by all members. For example, they can decide on safety, opportunities, leadership, among other matters. So the correct answer is A. Community members brainstorm ways to improve overall safety.
