Particle A, moves with acceleration 0.1m/s2 passing point P with speed 1.3m/s. After 6 seconds, particle B moves with acceleration 0.25m/s2 passing the same point P with speed 0.5m/s. B passes through A when both particles are same speed 6.4m/s and wm/s. Find the value of w.
Assess the symmetry of your body measurements by computing the proportions of your body using phi.
In a school, 200 students have access to three software packages, A, B and C
56 did not use any software
16 used only packages A
52 used only packages B
14 used only packages C
20 used all three packages
26 used both A and B
1. Draw a Venn diagram with all sets enumerated as for as possible. Label the two subsets
which cannot be enumerated as x and y, in any order.
2. If twice as many students used package B as package A, write down a pair of simultaneous
equations in x and y.
3. Solve these equations to find x and y.
4. How many students used package C?
5. How many students used package B?
