1. c(Q) 100 + 10Q + Q2 A. what are the formula fixed cost, variable cost, and marginal cost?
B. At want output level Q is average cost lowest?
C. What is the minimum average cost, AC?

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

idk wbu

step-by-step explanation:

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)

the correct answer would be d because the slope is -2/2=1 and the y intercept is at 2 so that is the correction equation
