Answer:
The answer is A or D
Step-by-step explanation:
Use a graphing calculator to graph. Then, you can add the zero by finding where it intercepts the x- axis. Then, the asymptotes are lines that the rational function doesn't touch. Like this. The asymptotes are the Green and blue lines, the zero is at the origin.
Decompose each velocity in its i and j - coordinates.
1) River's velocity
3.5 m/s, west fo east = 3.5i + 0j
2) Luke's velocity
5m/s, 60° east of north
5* sin(60°) i + 5*cos(60°) j = 4.33 i + 2.5 j
3) Resultant velocity
[3.5i + 0j] + [4.33i + 2.5j] = 7.83i + 2.5j
resultant speed = √[ (7.83)^2 + (2.5)^2 ] = 8.22 m/s
angle = arctan(2.5 / 7.83) = 17.7° north of east (equal to 72.3° east of north).
