Question

if the distance between the points (4,k)and (1,0) is 5 then what can be the possible value of k

Answer 1

just use distance formula

Answer 2

Hello shivi:-)

————————

Coordinates of A=(4,k)

——————-of B=(1,0)


So,

DISTANCE FORMULA ACCORDING


Root over
( x2-x1)square +(y2-y1)square.

X2=1. Y2=0

X1=4. Y1=K

Therefore,

Root over,

3 sq. +k sq=5

So squaring bore side.

9+ksquare=25

K sq. =16

K= +- 4
