Shouldn't there be four parts to this piecewise function...? Shouldn't "30" be in one of the domain for one of the rules? If the two-dollar fee is...

I don't understand the reasoning for the "1 + 0.45 - (0.45/3)" computation. Also, surely information is needed regarding the probabilities of parts...

Try using what you learned back in algebra: Did you do the graph of the original function, where y was in terms of x? If so, did you note the...

Multiply 1.05 by 1.05 by 1.05 by 1.05 by 1.05 by 1.05 by 1.05 by 1.05 by 1.05 by 1.05, just like the exponent tells you to! ;)

The "trick" for these is to multiply through by 2^N to convert this to a quadratic form. (No, I didn't figure this out on my own, either; somebody...

What is this? Do you mean that you took the derivative, so "-5*2t+20=-10t+20" means the following: . . . . .s'(t)\, =\, 20\, -\, 5\,(2t)\, =\,...

I second this opinion, and state further that it would likely be very wise of you to do as many of these exercises as you can. They can be painful...
