A distress flare is shot 85° up from a ship's bridge 75ft above the water with an initial velocity of 76ft/sec. What is the
maximum height of the flare, to the nearest foot?

Answer asap! show all work! find the number of complex roots, the possible number of real roots and the possible rational roots of the polynomial function. then, solve for all roots. x^3 + 2x^2 + 3x + 6 = 0
