Question: code class = asciimath > 1 . Ar bar ( a ) ta i c ( 4 - ( 1 ) / ( 4

code class="asciimath">1. Ar\bar (a) tai c(4-(1)/(4))*(8)/(15)=2.2. Determinati numrul real m,tiind c punctul A(1,5) aparine graficului funciei f:R->R, f(x)=x^(2)+m.3. Rezolvai n multimea numerelor reale ecuatia \sqrt(x^(2)+x+1)=1.4. Calculai probabilitatea ca, alegnd un numr n din mulimea A={1,2,3,4,5,6,7,8,9}, acesta s verifice egalitatea (n-2)(n-4)=0.5.n reperul cartezian xOy se consider punctele M(0,3),N(4,3)i P(4,0). Calculai perimetrul triunghiului MNP.6. Artai c sin^(2)120\deg-cos^(2)30\deg =0.
