Q1.the cubic equation

where p and q are constants, has three complex roots, a, b and y (alpha, beta and gamma). it is given that b = -2+3i and y = 1 + 2i.
(a)(i)write down the value of aby.
(ii)hence show that (8 + i)a = 37 - 36i.
(iii)hence find a, giving your answer in the form m + ni, where m and n are integers.

The heaviest 16% of all men in weight weigh more than how many pounds ?

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .
