The rise is the vertical distance between the two points, which is the difference between their y-coordinates. That makes the rise y2 − y1. The run between these two points is the difference in the x-coordinates, or x2 − x1.
X,x because we dont know its value
Answer:
Step-by-step explanation:
Given
Position of particle is 
i.e. distance from x axis is 
Distance from y axis at
velocity is given by 

Similarly acceleration is given by


Magnitude of acceleration is 

From 1 and 2 we can see that
Magnitude of acceleration is proportional to distance from x axis

Answer: 
Step-by-step explanation:
Given : Distance traveled by Lily= 354 miles
Time= 6 hours
Then,

Hence, the required speed of Lily =
