T = 9 = 0.005x^2 + 0.002x

0.005x^2 + 0.002x - 9 = 0

To solve this quadratic equation divide by 0.005

x^2 + 0.4x - 1800 = 0

x = {-b +/- √[b^2 -4ac] } / 2a = {-0.4 +/-√[0.16 + 7200]} / 2 = { - 0.4 +/- 84.85}/2 =

Use only the positive result: x =  42.2 = 42

Answer: 42

The OSI Model is known to be a kind of a logical and conceptual framework that tells all about network communication that is often used by systems in an open to interconnection and also in any communication with other forms of systems.

Note that the Open System Interconnection (OSI Model) is one that tells more about a logical network and it is one that also tells about computer packet transfer via the use of various layers of protocols.

Therefore, The protocols  that are often used in each layers in each OSI reference model are:

Layers                           Protocols

Layer 7- Application          SMTP, HTTP, FTP, POP3, SNMP
