A vehicle factory manufactures cars. The unit cost (the cost in dollars to make each car) depends on the number of cars made. If
Nataly [62]

Answer:

The function is missing in the question. The function is $ C(x) = 0.8x^2 -544x +97410 $

The answer is 4930

Step-by-step explanation:

Unit cost of a car is given as

$ C(x) = 0.8x^2 -544x +97410 $

Cost will be minimum when

x = -(-544)/ 2 x 0.8

  = 340

Therefore, minimum cost for unit car is

$ C(x) = 0.8x^2 -544x +97410 $

$ = 0.8(340)^2 -544(340) +97410 $

=  4930

The ratio of nonfiction books to fiction books in a library is 105 to 189. Which statement describes this relationship?
kolezko [41]

Answer: A)There are 5 nonfiction books for every 9 fiction books in the library.  

Step-by-step explanation: If you do the math you realize that there are clearly less nonfiction books than fiction books.

105/5=21 and after 21*9 lines up and to check your work than

5*21=105 and 9*21=189 it is not B because the smaller number 105 is in front of the ratio 105:189 and 5:9

Can anybody explain to me what is being done here ?
bija089 [108]

Answer:

So first, they remove the denominator of x times x, because multiplication cancels out division, so then you're left with

3/1 times x = 2193

3/1 just equals three, so you write it down as 3.

3x = 2193

To isolate 3x, you need to divide by 3.

x = 731

Hope this helped :)
