Aregular polygon is inscribed in a circle of radius 11 cm. calculate the perimeter of the polygon to the nearest tenth if the polygon has 8 sides.

Initial value , rate of change:

Step-by-step explanation:

Step 1

Find the rate of change

we know that

In a linear equation the rate of change is equal to the slope

The formula to calculate the slope between two points is equal to  

we have

Substitute the values  

 ----> rate of change

Step 2

Find the initial value

The equation of  the line into slope-point form is equal to

Substitute

The initial value is the value of y when the value of x is equal to zero (is the y-intercept)
