Question

A ball is released at a height of 16 inches to roll inside a half-cylinder. It rolls

Answer 1

Answer: 1/2 inch

Step-by-step explanation: Letter d

Answer 2

Answer:

$\boxed{\dfrac{1}{2} \text{ in}}$

Step-by-step explanation:

aₙ = 8(½)ⁿ⁻¹

If n = 5

 a₅ = 8(½)⁵⁻¹

 a₄ = 8(½)⁴ = 8 × ¹/₁₆ = ½ in

$\text{On its fifth time, the ball will roll \boxed{\mathbf{\dfrac{1}{2} in}} up the cylinder's side}$
