simplify the expression below and state the value of m for which the simplified expression is not defined 2m² + m - 15/ m² - 9​
motikmotik

Answer:

  • The simplified expression is: \frac{2m-5}{m-3}
  • The simplified expression is undefined for m=3

Explanation:

The given expression is:

\frac{2m^2+m-15}{m^2-9}

The numerator can be siplified by using factorization and denominator will be simplified using the formula

a^2-b^2 = (a+b)(a-b)

So,

= \frac{2m^2+6m-5m-15}{(m)^2-(3)^2}\\=\frac{2m(m+3)-5(m+3)}{(m-3)(m+3)}\\=\frac{(2m-5)(m+3)}{(m-3)(m+3)}\\=\frac{2m-5}{m-3}

A fraction is undefined when the denominator is zero. In order to find the value of m on which the simplified fraction will be undefined we will put denominator equal to zero.

So,

m-3 = 0 => m = 3

Hence,

  • The simplified expression is: \frac{2m-5}{m-3}
  • The simplified expression is undefined for m=3

"what is the problem with using challenge handshake authentication protocol (chap) as an authentication protocol?"
Alexxandr [17]

Its use of the message digest 5 (MD5) hash algorithm for security.

CHAP uses a combination of MD5 hashing and a challenge-response mechanism, and authenticates without sending passwords as plaintext over the network. The security of the MD5 hash function is severely compromised.

Answer:

3

Explanation:

The function floor() is used to give the integer which is smaller than or equal to the provided decimal value.

for example:

let a=5.8

floor(a);

the function provides the value 5 (smaller than or equal to 5.8).

In the given code:

variable num assigns the number 3.14.

then, floor(3.14) gives the value 3 (smaller than or equal to 3.14).
