A software requirements specification $$(SRS)$$ document should avoid discussing which one of the following?

Consider the basic $$COCOMO$$ model where $$E$$ is the effort applied in person-months, $$D$$ is the development time in chronological months, $$KLOC$$ is the estimated number of delivered lines of code (in thousands) and $${a_b},{b_b},{c_b},{d_b}$$ have their usual meanings. The basic $$COCOMO$$ equations are of the form

The number of states in the minimal deterministic finite automaton corresponding to the regular expression $${\left( {0 + 1} \right)^{\,\, * }}\left( {10} \right)$$ is ________________.

Which of the following languages is/are regular?

$${L_1}:\left\{ {wx{w^R}|w,x\, \in \left\{ {a,b} \right\}{}^ * } \right.$$ and $$\left. {\left| w \right|,\left| x \right| > 0} \right\},\,{w^R}$$ is the reverse of string $$w$$
$${L_2}:\left\{ {{a^n}{b^m}\left| {m \ne n} \right.} \right.$$ and $$m,n \ge \left. 0 \right\}$$
$${L_3}:\left\{ {{a^p}{b^q}{c^r}\left| {p,q,r \ge 0} \right.} \right\}$$
