a supply company manufactures copy machines. the unit cost
c
(the cost in dollars to make each copy machine) depends on the number of machines made. if
x
machines are made, then the unit cost is given by the function
=cx+−0.5x2350x69,950
. what is the minimum unit cost?

Iwill give you ! what is the measure of ∠v ?

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
