Question

If the distance between the points (4, k) and (1, 0) is 5, then what can be the possible values of k?​

Answer 1

Answer:

we use distance formula here then equate 5 with the equation so formed

Answer 2

Answer:

Step-by-step explanation:

$A(x_1, y_1), B(x_2, y_2)$

$l=\sqrt {(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}$

l is the distance between A and B.

$5=\sqrt{9+k^{2} }$

$25 = 9 + k^{2}\\k^{2} = 16$

$k=4, k=-4$
