Answer:
A A A B B B C C C
Step-by-step explanation:
We have the Greedy algorithm, the solution at any time is considered an optimal algorithm.
In our case the sequence is x x x y y y z z z
In addition to the Greedy algorithm, the first advertiser chooses their choice without considering the minimum methods.
Now we must consider the worst case of greedy algorithm so we must suppose that it starts from advertiser C, then B and followed by A.
Therefore the worst option would come being:
C C C B B B, in addition that A cannot bid for any query.
Which means that the sequence of the balanced algorithm will be A A A B B B C C C
Distance formula: d= square root of (x2-x1)^2+(y2-y1)^2
(3,5) (7,3)
d= square root of (7-3)^2+(3-5)^2
d= square root of (4^2)+(-2^2)
d= square root of 16+4
d= square root of 20
d=4.47...rounded= 4.5
Hope this helped!
Answer:
d
Step-by-step explanation:
Factoring using difference of squares
a² - b² = (a - b)(a + b)
a
x² - 1
= x² - 1²
= (x - 1)(x + 1)
b
x² - y²
= (x - y)(x + y)
c
x² - 4
= x² - 2²
= (x - 2)(x + 2)
d
4 - 16y ← 16y is not a perfect square and so cannot be factored
If it was 4 - 16y² then it could be factored using difference of squares
I did my math and I think 41 minuets but are u adding or subracting
