Proceeding through a sequence of numbers term by term, we calculate a running tally as follows. The tally starts at zero. Starting with the first term, a term is subtracted from the running

tally if the result is non-negative, otherwise it is added to the tally. When we arrive at the end

of the sequence, the resulting tally is called the roman sum of the sequence. For instance, the

roman sum of the sequence 2, 4, 3, 3, 1, 5 is 0 +2 +4-3-3+1+5 = 6.

For a sequence consisting of the numbers 1, 2, 3, ... , 100 in some order, what is its largest

possible roman sum?

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)

5x10^11 x 65

325 x 10^11

or

325,
