The following table shows the crude steel production in the​ USA, in millions of metric tons. 1980 0 80
1985 5 90
1991 11 91

​(A) Find a quadratic function ​f(x) that fits the​ data, where x represents the number of years after 1980.
​f(x) X^2+20833x+80
nothingxx80.
​(Round to three decimal places as​ needed.)

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !

10 you would take 50/ .2

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
