Hi, I need to calculate the magnitude of the initial velocity of the following data for projectile motion. Any help would be greatly appreciated as I have no idea where to start! Thanks please see the question here: http://i52.tinypic.com/15p0kza.png and the data here...

Assuming that the decay rate for each population does not change before the populations are equal: (a) A = 2000(1 - 0.05)^n So A = 2000 * 0.95^n [eqn 1] B = 3000 * 0.90^n Now pops are the same when A = B so 2000 * 0.95^n = 3000 * 0.90^n 0.95^n / 0.90^n = 3/2 Taking logs to base 10 of both...

I have the same problem working out this, I don't know where to start, Could someone please help.

sponsoredwalk, that's awesome explaining, but can you work it out for us in just a few steps?

the lower case x's with spaces either side are multilpication signs please Help, I'm really stuck

Could somebody please do this as an example, this is just the first one in the list I have to do. Thankyou

I'm sorry but that example made no sense to me at all? I need more explanation.

Ok, so I have this Expression, (6x+2 x 42x-4 x 35-x x 2x-6)/(124x+3 x 92x-3) But it needs to be simplifyed, and expressed with positive indices. Now as far as my knowledge takes me, this can't be simplifyed, but then I am probably wrong. If anybody could help to solve, that would be great.

This is all I know, I don't know what method should be used to find the answer?

A fixed deposit investment attracts interest of 4.3% p.a. compounded annually. How long will $30 000 take to double in value?

just one more question, how do I simplify this and express with positive indices. (18x^3 X 2x^-4)/(4x^-5 X 6x)

Thankyou Very Much! :D

Simplify and express with positive indices, a little help? I am no good at these, can anyone show me how to work these out? (18x3 X 2x-4)/(4x-5 X 6x) 83sqrt(p12 q-8) X 34sqrt(p-10 q9) and (6x+2 X 42x-4 X 35-x X 2x-6)/(124x+3 X 92x-3) ps. The Capital X's are multiplication signs

The second problem, I worked out to be just 12 now. But the first problem, 2/1.75 equals a long decimal, so wouldn't I just leave it as a fraction?
