El mar está tranquilo y la lancha patrullera está en perfectas condiciones. Si el mar está tranquilo o la lancha patrullera está en perfectas condiciones, entonces el personal de resguardo alcanzará a la nave en cinco horas. Si el personal de resguardo alcanzará a la nave en cinco horas, entonces el equipo de emergencia podrá actuar eficazmente. Luego, el equipo de emergencia podrá actuar eficazmente. METODO DELAS DERIVACIONES

step-by-step explanation:

the true ones are a b and d

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.
