Let f(x)- x^3-4x^2+6x-2 and let a, b and y be roots of f(x) in c. find polynomials that have (a) a+b+y as a root (b) a^2+b^2+y^2 as a root hint: elementary symmetric functions

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
