Answer:
Given: and
.
Prove:
Since , By the definition of perpendicular lines angles 1, 2, 3 and 4 are 90 degree. similarly
, it means angles 5, 6, 7 and 8 are 90 degree.
We can say that,
,
,
and
From figure it is noticed that the angle 1 and 5 are corresponding angles.
If two parallel lines are intersected by a transversal, then the corresponding angles are equal.
Since corresponding angles are congruent, therefore the line must be parallel to each other.
Hence proved that .
Answer: 1
Step-by-step explanation:
So, the average rate of change is:
The question is wrong, the expression will not be in terms of h since it is a linear function.
