Option (4) 12
a2 + b2 = 25
So, possible solution sets (a,b) are
(±5,0),(0,±5)
(±3,±4) and (±4,±3)
So there are 2 + 2 + 4 + 4 = 12 possible points.
:)
How
many different points in the X-Y plane are at a distance of 5 units
from the origin and have co-ordinates (a, b), where ‘a’ and ‘b’ are
integers?
(0,5)(0,-5),(5,0),(-5,0),(4,3),-4,-3),(-4,3),(4,-3),(3,4),(-3,-4),(-3,4),(3,-4)
the answer is 12 pts....
Yes Answer will be 12 .
yes ans is 12....
i too agree wid all of u....the answer is 12...
ya thats correct
