8. $9 *0.7= $6.30
Answer:
24.2
Step-by-step explanation:
divide 60.50 by 30 then multiply that by 12
So all you need to do if find the min of the function:
f(x)=0.04x^3-4x^2-176x
f'(x)=0.12x^2-8x-176
The only zero for this is x=84.105 <---first
Plug this into f(x) to get f(84.105)=-19300 <---second
The line is parallel to y axis
We know that if a line is parallel to y axis
So there is no slope
Here it has constant x value as -2
So the equation is
Option A
