Answer:
-1 = (-3/5)-15 + b
(I don't know the y-intercept bc I don't have a graphing calc but to find it out you just graph it and then see where the line passes thru the y axis)
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:
the probability is 0.125
Step-by-step explanation:
The number of ways in which the mouse can move in the 4 turns is calculated using the rule of multiplication as:
<u> 2 </u>* <u> 2 </u> * <u> 2 </u>* <u> 2 </u> = 16
1st turn 2nd turn 3rd turn 4th turn
Because the mouse can take two options at every turn, right or left.
Now, from the 16 possibilities of movements, a mouse will find an exit in just two options:
1. right-right-left-left
2. left-right-right-left
So, the probability that a mouse will find an exit is:

Because, there are 16 possibilities and a mouse will find an exit using 2 of them.
