a supply company manufactures copy machines. the unit cost C (the cost in dollars to make each copy machine) depands on the number of machines made. if x machines are made, then the unit. coat is given by the function. C(x)=0.7^2-490x+101,483. what is the minimum unit cost. do not round​

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.
