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

Answerthe force between the charges will be  f/9 (one-ninth of force f)explanationcoulomb's law relates the magnitudes  two point charges q₁ and q₂, the distance, r, between the charges, and the electrostatic force, f, between the two charges:     k represents coulomb's constant, k = 8.99×10⁹ n·m²/c².note that if we have r = 3r, then   

Answerthe valence of an element or radical is equal to the number of positive or negative charges on the ion.

Cannot be determined because i dont  know this but i need the points

Jenny and fred both play a long note on their trombones. a stationary observer hears the sound increasing and decreasing repeatedly in loudness. which of these must be true? the sound waves from the two trombones have slightly different frequencies.the sound waves from the two trombones have the same frequency.the sound waves from the two trombones have slightly different amplitudes.the sound waves from the two trombones have the same wavelength.the sound waves from the two trombones have slightly different velocities.  lolthe answer is          the sound waves from the two trombones have slightly different frequencies.
