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
#See attached photo for illustration
Answer and Explanation:
The ball is bouncing to a height of 1/3 of its previous height this is a type of geometric sequence the total distance can be found by the sum of geometric sequence
For example let the initial height is 243 fit
After one bounce it will reach 243/3 =81 feet
After second bounce 81/3=27 feet
After third bounce 27/3 =9 feet
After fourth bounce 9/3 =3 feet
So a sequence is formed that is 243,81,27,9,3..........
Here
Sum of infinite GP =
From this formula we can find the total distance traveled by the ball
