Answer:
They traveling at
in backward direction.
Step-by-step explanation:
Given mass of Ammy 
and velocity is forward at 
Also, mass of Jenny 
Who is travelling in opposite direction 
Let velocity in forward direction is positive and velocity in backward direction is negative.
Also, velocity after crash is 
As they crashed into each other and they moved as one mass. We can apply principle of conservation of momentum.
Conservation of momentum says momentum before collision should equal to momentum after collision.


So, velocity after collision
≅
is in opposite direction. That is the direction of Jenny.
Answer:
6 feet
Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = 2πr ← r is the radius, thus
2πr = 12π ( divide both sides by 2π )
r =
= 6
1 in equals 25.4mm exactly so
.25in(25.4mm/in)=6.35mm
Answer:
The rational roots of the equation are:
x= -1.10355
x= 0.148953
x= 0.706883
x= -1
Step-by-step explanation:
We have to find the rational solutions of the algebraic equation:

This equation could also be written as:

for finding the roots of the equation we have to find the possible values of x.
Clearly the equation has 8 roots as the degree of the equation is 8.
from the graph of the following function we could see that the rational roots of the function are:
x= -1.10355
x= 0.148953
x= 0.706883
x= -1
The rest 4 roots of the equation are the complex roots.
