Question

8. If the distance between the points (4, p) and (1, 0) is 5, then the value of p is
(a) 4 only
(b) + 4
(c) - 4 only
(d)0​

Answer 1

Answer:

p can be both +4 & -4

Step-by-step explanation:

To solve this question with distance formula kindly refer to the attachment.

or

A(4,p) B(1,0)

B point lie on x axis

horizontal distance between A and B = 4-1

=3units

vertical distance between A And B = p units

distance between A and B = 5units

Using Pythagoras theorem

p = 4units

Now since we take distance as +ve always

therefore p can be +4 or -4

as the end result would be same.
