Answer:
Slope of the line perpendicular to the given line = 
Step-by-step explanation:
If two are lines are perpendicular to each other,
the product of their slopes = - 1 .
That is ,

Slope of the given line :

Hence slope of the line perpendicular to it :

Answer:
sin²x
Step-by-step explanation:
we have
(1 − cos x)(1 + cos x)=1-cos²x
Remember that
sin²x+cos²x=1 ------> i-cos²x=sin²x
therefore
(1 − cos x)(1 + cos x)=sin²x
Answer:
12.8
Step-by-step explanation:
The mean is 5.2 so,
|7 - 5.2| + |6 - 5.2| + |3 - 5.2| + |9 - 5.2| + |1 - 5.2| = 12.8
