I just worked for a few hours on a project in InDesign and then saved the file. I then by mistake saved another file under the same name and same location, and when prompted whether I was sure that I wanted to replace the file, I chose 'yes'. Is there any way of retrieving the original file which I had saved? All help is much appreciated!

What organisms do fireflies compete with?

Do fireflies enter any symbiotic relationships with other organisms, including mutualism, commensalism, and parasitism?

What biotic and abiotic factors affect fireflies?

a) A simple pendulum consists of a small metal ball attached to a fixed point by a cord of length l centimetres. It takes T seconds to make one swing, where T=0.2sqrtl. Find dT/dl. (This I have solved) b) The cord originally has length 2.5 metres. If it is lengthened by 2 millimetres, calculate what effect this will have on the time of swing: I) by using your answer to part a. II) by direct evaluation of T.

The equation of a curve is y=ax^2-2bx+c, where a, b and c are constants with a>0.

(a) Find, in terms of a, b and c, the coordinates of the vertex of the curve.

(b) Given that the vertex of the curve lies on the line y=x, find an expression for c in terms of a and b. Show that in this case, whatever the value of b, c>-1/4a or c=-1/4a.

So the vertex is on (b/a, c-b^2/a) and c=b(b+1)/a. Any ideas about the last part?
