Question

find the distance of the point p(4,-3,5) from xy plane

Answer 1

Answer:

the distance of the point p(4,-3,5) from xy plane = 5 unit

Step-by-step explanation:

to find the distance of the point p(4,-3,5) from xy plane

we will find minimum distance

at xy plane z = 0

for minimum distance point ( 4 , -3 , 0)

Minimum Distance = √(4-4)² + (-3-(-3))² + (0-5)² = 5 unit

To find exact distance co-ordinates of x & y will also required

Answer 2

Answer:

Distances between a plane and a point are measured perpendicularly. That means in your case the distance in question is nothing but the absolute value of the z-coordinate.

If the plane is not parallel to the coordinate planes you have to use a formula or you calculate the minimum of all possible distances, using calculus.
