OK. Then let's solve for ' r '. That means you have to come up with an equation that says r = everything else.
Step #1:
Write the equation you're given: <span>S = L (1 - r)
Let's divide each side by ' L ': S/L = 1 - r
Subtract 1 from each side : S/L - 1 = -r
Multiply each side by -1 : <em> 1 - S/L = r</em>
and there you have it.

The work is done on the toy car is 164.4 J .
<h3>How to calculate work done?</h3>
We are aware that the definition of work is the multiplication of the magnitude of the displacement (d) and the component of the force acting in the displacement direction.
When an object moves over a distance while being applied with force, the work is considered to have been completed.
Three categories can be used to classify the type of labor performed. Positive work, negative work, and zero work are the three types. The angle between force and displacement determines the kind of work that is done. Positive work is defined as any work that causes an object to move in the direction of the applied force.
Given ,
Work = force * distance
Force = 5.2 N
Distance = 32 m
So ,
Work = 5.2 * 32
= 166. 4 J
Therefore the work is done is 164.4 J

Answer:
Step-by-step explanation:
4
Answer:
9i
Step-by-step explanation:
Use the product property of radicals to simplify the following radical.
-81 can be break into 81 times -1
that is 81 and -1
as per the product property
square root (-1) is 'i'
square root (81) is 9
It would be 6 people did not get hurt
20 people, 14 got hurt, so subtract 14 from 20 and you get 6 which would be your answer.
Hope this helped. Have a great day!
