For the polynomial, \( P(x)=x^{3}-8 x^{2}+37 x-50,2 \) is one of the zeros. Find all remaining zeros. The remaining zeros are (Simplify your answer. Type your answer in the form \( a+b i \). Use a comma to separate answers as needed.)

5. The area of a square is \( 1,44 \mathrm{~mm}^{2} \). Calculate the perimeter of the square. 6. The perimeter of a square tile is 120 cm . Calculate the size of an area tiled with 20 of these square tiles.

3. En utilisant un tableau de vérité montrer que la proposition suivante est une loi logique \( (P \Rightarrow Q) \Leftrightarrow(\bar{Q} \Rightarrow \bar{P}) \) Où \( P \) et \( Q \) sont deux propositions mathématiques

8.1 point A 2.5 kg block is attached to a vertical spring and allowed to settle into an equilibrium position. The block is then pulled downward and released, setting it into oscillating motion with a frequency of 10.0 Hz . The spring constant ko of the spring is most nearly \( 100 \mathrm{~N} / \mathrm{m} \) Cannot be determined without knowing the initial displacement of the block \( 10000 \mathrm{~N} / \mathrm{m} \) \( 1000 \mathrm{~N} / \mathrm{m} \)

1.3 * Calcule o tempo em nanossegundos que a luz leva para percorrer uma distincia de \( 1,0 \mathrm{~km} \) no vácuo. (Este resultado ế uma grandeza importante de se lembrar.) 1.4 * A densidade do ouro é 19,3 g/cm³. \( { }^{3} \). Qual ê esse valor em quilogramas por metro cúbico?
