Answer: The vertical stretch of 5 in the equation y = x is defined by
.
Explanation:
The given equation is,

It can be written as,

The function is defined as
.
If
, then the function has a vertical stretch by a factor of S units.
If
, then the function has a vertical shrink by a factor of S units.
Since we have to find the vertical stretch of 5 in the equation y = x.


The below figure shows the graph of y = x and
.
When u keep dividing and dont get it go up by each number and keep divind by every number until u get it which would be
Given:
Radius of the circle = 10 in
Central angle of the sector = 45 degrees
To find:
The area of the sector.
Solution:
Area of a sector is

Where,
is the central angle in degrees.
Putting r=10 and
, we get



Therefore, the area of the sector is 12.5π sq. inches.
