Question

A spotlight on the ground shines on a wall 15 meters away. A man 1.8 meters tall walks away from the spotlight toward the building. Write the height of the shadow (s) as a function of the distance (d) from the man to the building.

Answer 1

`s=(15-x)m`

Step-by-step explanation:

Let the distance from spotlight to wall be 15m, and distance from the man to the building be
`x`.

#Therefore the height of the shadow as a function of the above is
`s=(15-x )m`

Hence, height of the shadow is expressed as s=(15-x)m
