The answer is B!
I could explain further if needed!
Answer:(a) n=0.233
Step-by-step explanation:
Given
We Know according to Taylor tool life

V=cutting speed
T=tool life
n=tool life exponent
c=constant



taking log both side

n=0.233
The formula for determining the apothem of regular hexagon is s/2tan(180/n) , where 's' is any side length of regular hexagon and 'n' is the number of sides of regular hexagon.
So, apothem = 17/2tan(180/n)
= 17/2tan(30)
= 17/1.15
= 14.78 units
Therefore, the measure of apothem of the regular hexagon is 14.7 units.
B is the right answer.
