Step-by-step explanation:
Finding the average skid distance:
Calculating the skid:
This involves quite a lot of arithmetic to do manually.
The first thing you do is to make the first number in row 2 = to 0.
This is done by R2 = -3/2 R1 + R2
so the matrix becomes
( 2 1 1) ( -3 )
( 0 -13/2 3/2) (1/2 )
(5 -1 2) (-2)
Next step is to make the 5 in row 5 = 0
then the -1 must become zero
You aim for the form
( 1 0 0) (x)
(0 1 0) (y)
(0 0 1) ( z)
x , y and z will be the required solutions.
Answer: m = 16
Step-by-step explanation:
2m² + 16 = 2m
2m² - 2m = 16
m = 16
7-12 is like a negative number so it will be -5. And 13-18 would be -5 also.
