Step-by-step explanation:
The pair of segments on the right tells you the ratio of the segment length above the horizontal line to that below the horizontal line is ...
18 : 6 = 3 : 1
Then x = 3 times 5 = 15.
12 is 3 times y, so y = 4.
We are asked in the problem to determine the number of quarters that are needed to complete 4975 units given the equation y = x6 − 25x4 + 199x2 where y is the number of manufactured units and x is the number of quarters needed.
substituting y = 4975, we find x. <span>x is readily found using calculator.</span>
