Question: The question is incomplete. The bicycle chain diagram wasn't attached to your question. Find attached of the diagram and the answer.
A bicycle chain is pulled tightly so that mn is a common tangent of the gears. Find the distance between the centers of the gears.
Answer: The distance between the centers of the gears is 17.8 in
Explanation:
From the attached file, using Pythagoras theorem to find the value of x, we have;
h = 4.3 - 1.8
= 2.5
x² = MN² + h²
x² = 17.6² +2.5²
x² = 309.76 + 6.25
x² = 316.01
x = √316.01
x = 17.8
Therefore, the distance between the centre of the gear is 17.8 in
Answer:
It is 1.12 (B)
Explanation:
Profitability Index= PV of Future cash flow/Initial Investment
= $72,800/$65,000
=1.12
The index is a useful tool for ranking investment projects and making decision most especially when there is limited capital availbal and all the viable projects cannot be executed. It showed the value created per unit of investment.
Hence, the higher the profitability index, the more attractive the investment is.
