Mathematics
1 answer:
Anastaziya [24]3 years ago
5 0

Step-by-step explanation:

Domain = {5,x}

Range = {-2, y}

For being a function, one domain cannot have more than one range.

If x=5, then y will be the range for x=5. But 5 already has a range -2 in (5,-2). So, x can be any real number except 5 and y can be any real number

A circle whose center is the origin passes through the point (-5,12). Which point also lies on this circle?
schepotkina [342]
The answer is B(11, 2sqrt(12) )
proof

the main equation of the circle is   (x-x1)²+(y-y1)²=R²
where C(x1, y1) is the center 
so if the center is the origin, it is O(0,0), and the equation becomes
<span>  (x)²+(y)²=R²
</span>and the circle passes through the point (-5,2) so we can write 
(-5)²+12²=R², it implies R= sqrt(25+144)=sqrt(169)=13

and  for <span>B(11, 2sqrt(12) )     </span>11²+  (2sqrt(12))²= 121 + 48= 169= 13
it is checked.
