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.

Explanation:

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

#Therefore the height of the shadow as a function of the above is

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

okay i have so many questions. but the big one here is: um wt..f is this mess? ?

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
