I need help with the following proof:

If the domain of a continuous function is an interval, show that the image is an interval.

This doesn't seem like it should be that hard, but I'm having trouble putting it into "math" terms. Thanks.

Prove:
sin (pi-x)= sin (x) using the addition identity

And
how to find (without a calculator):
sin 40 degrees and cos 40 degrees if sin 20 degrees is approximately equal to 3 and cos 20 degrees is approximately equal to .9


I don't need the answer just a little bit about how to do the problems. Thank You

Graph f, g, and h in the same rectangular coordinate system for
0 < or equal than x < or equal than 2π. Obtain the graph of h by adding or substracting the corresponding y-coordinates on the graphs of f and g.

f(x) = sin x, g(x) = cos2x, h(x) = (f-g)(x)

I need help with this problem. Correct answer gets 10 points.

An open cylindrical container made from sheet metal of uniform thickness has a mass of
800 g. When completely filled with water the total mass is 15.6 kg.

What would be the total mass of a cylindrical container full of water made from the same sheet metal (of the same thickness) but with double the diameter and double the height?

A 118.4 kg
B 121.6 kg
C 124.8 kg
D 128 kg
E 131.2 kg

Please provide working... i did 15.6/0.8 to get 19.5 but then i get stuck.. any help would be greatly appreciated!

Thanks, Ellie x
