Answer:
a. How long will the current bridge system work before a new bracing system is required?: 64.18 years or 64 years and 2 months.
b. What if the annual traffic rate increases at 8 % annually: The bracing system will last for 24.65 years or 24 years and 7 months.
c. At what traffic increase rate will the current system last only 12 years: 17.13%
Explanation:
a. Denote x is the time taken for the number of pedestrian to grow from 300 to 2000. The current pedestrian is 300, the grow rate per year is 3% or 1.03 times a year. Thus, to reach 2,000, we have the equation: 300 x 1.03^x = 2000. Show the equate, we have 1.03^x = 6.67 <=> x = 64.18
b. Denote x is the time taken for the number of pedestrian to grow from 300 to 2000. The current pedestrian is 300, the grow rate per year is 8% or 1.08 times a year. Thus, to reach 2,000, we have the equation: 300 x 1.08^x = 2000. Show the equate, we have 1.08^x = 6.67 <=> x = 24.65.
c. Denote x as traffic increase rate. The current pedestrian is 300, the grow rate per year is (1+x) times a year. Thus, to reach 2,000 after 12 years and thus a new bracing system to be in place, we have the equation: 300 x (1+x)^12 = 2000. Show the equate, we have (1+x)^12 = 6.67 <=> 1+x = 1.1713 <=> x = 17.13%.
The exact meaning of the signals exchanged between a sender and a receiver is called as a Network protocol.
<h3>What Is a Network Protocol?</h3>
A network protocol is a set of rules that determine how data is transmitted between different devices in the same network.
Because of the Network protocols we can easily communicate with people all over the world, and thus play a critical role in modern digital communications.
Similar to the way that speaking the same language simplifies communication between two people, network protocols make it possible for devices to interact with one another because of predetermined rules built into devices’ software and hardware.
Neither local area networks (LAN) nor wide area networks (WAN) could function the way they are doing today without the use of network protocols.
