Answer:

Step-by-step explanation:
If a third drop out, Initial fraction of those who graduate = 
Three-fifths of those who dropped out(one third) eventually return = 
The proportion of students entering high school who eventually graduate
= Those who graduated Initially+Those who returned
=
To determine the scale factor of the dilation, we determine the distances between the endpoints of the two lines through the equation,
d = √(x₂ - x₁)² + (y₂ - y₁)²
Substituting the known values.
Line Segment 1: d = √(1 - 2)² + (4 - 8)² = 4.123
Line Segment 2: d = √(18 - 14)² + (12 - 1)² = 11.70
Dividing the answers will give us 0.352
Answer:
Part A) Not collide
Part B) k = 4
Part C) Particle B is moving fast.
Step-by-step explanation:
Two particles move in the xy-plane. At time, t
<u><em>Position of particle A:-</em></u>


<em><u>Position of particles B:-</u></em>

Part A) For k = -6
Position particle A, (5t-5,2t+6)
Position of particle B, 
If both collides then x and y coordinate must be same
Therefore,
5t - 5 = 4t
t = 5



The value of t is not same. So, k = -6 A and B will not collide.
Part B) If both collides then x and y coordinate must be same
5t - 5 = 4t
t = 5

Put t = 5


Hence, if k = 4 then A and B collide.
Part C)
Speed of particle A,

Speed of particle B,

At t = 5

Hence, Particle B moves faster than particle A
