Not sure how to due this problem.

a vehicle factory manufactures cars. the unit cost (the cost in dollars to make each car) depends on the number of cars made. if x cars are made, then the unit cost is given by the function c (x) = x^2 - 320x + 40,052 . what is the minimum unit cost? do not round your answer.

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)

If f(x)=-x^2+6x-1 and g(x)=3x^2-4x-1,find(f+g)(x)

The map shows the location of the airport and a warehouse in a city. though not displayed on the map, there is also a factory 112 miles due north of the warehouse. a truck traveled from the warehouse to the airport and then to the factory. what is the total number of miles the truck traveled?
