Mathematics Test 11 - Straight Line, Circle - Question 1

### A point P on y-axis is equidistant from the points A(–5,4) and B(3,–2). Its co-ordinates are

Mathematics Test 11 - Straight Line, Circle - Question 2

### If the point P(x,y) be equidistant from the points A(a b, b–a) and B(a–b,a b), then

Detailed Solution for Mathematics Test 11 - Straight Line, Circle - Question 2
PA=PB
take square both side
PA^2=PB^2

now use distance
formula ,
{x-(a+b)}^2+{y-(b-a)}^2={x-(a-b)}^2+{y-(a+b)}^2

=>x^2+(a+b)^2-2x(a+b)+y^2+(b-a)^2-2y(b-a)y=x^2+(a-b)^2-2x(a-b)+y^2+(a+b)^2-2y(a+b)

=>2x(a-b)-2x(a+b)=2y(b-a)-2y(a+b)

=>2x{a-b-a-b}=2y{b-a-a-b}

=>2x(-2b)=2y(-2a)

=>bx=ay

Mathematics Test 11 - Straight Line, Circle - Question 17
Two circles and 0 are such that they
Detailed Solution for Mathematics Test 11 - Straight Line, Circle - Question 17 These are the equation of two circles.The best way to find out whether two circles touches or cuts or do not intersect is to find out the distance between their centres.If this distance is greater than the sum of their radii they don't touch,if equal to sum of radii they just touch, and if less than sum of radii then intersect at two points. If distance is zero then they are concentric.

Detailed Solution for Mathematics Test 11 - Straight Line, Circle - Question 23
Centre of the given circle is - (-12/2) , - ( -4/2)
This means (6,2) is the centre of the circle.
The farthest point from the origin on the circle has to be the far end of diameter got by joining (0,0) and (6,2)
Equation of line joining these two points is by two point formula
We have x = 3 y
The point of intersection of this line and circle is got by solving these two
We get points (3,1) and (9,3)
Hence required farthest is (9,3)
