#24168 2oo2 Paper 2 - Question 6

Posted by gary on 17 May 2005 - 09:10 PM in Mathematics

Firstly you do:

Y= 2 sin (pie/3 - pie/6)
= 2 sin (pie/6)
= 2x0.5
= 1

point (pie/3,1)

Then

differentiate

2 cos(pie/3 - pie/6)
2 cos(pie/6)
2xroot 3/2
root 3

then using y-b=m(x-a)

y-1 = root 3(x-pie/3)
y-1 = root 3x - root3pie/3

#7916 Help With Questions

Posted by gary on 24 October 2004 - 09:54 AM in Chemistry

The mass of one mole of aluminium is 27g.
What is the mass of one aluminium atom?

What volume of Carbon dioxide is produced when 10cm3 of ethane is burnt in pure oxygen?

What volume of hydrogen is produced when 2g of magnesium reacts with excess hydrochloric acid according to the equation (assume the molar volume is 24 litres)

The combustion of ethan can be summarised by the equation

C2H6(g) = 3 1/2 02(g) gives 2CO2(g) + 3H20(g)

If air is 20%, by volume of oxygen how much air is needed to completely burn 10 litres of ethane?

Posted by gary on 10 October 2004 - 10:34 AM in Mathematics

A rectangular flag is to have trimming attached along 3 of its sides. The length of the trimming is 240 centimetres.

If x centimetres is the length of the flag, show that the area of the flag, A square centimetres, is given by A(x) = 2x (120-x).

Also can anyone help with this fraction it has puzzled me because my final answer has came out weird:

9/1 x 1/81 - 2/1 x 1/9
