about simple interest..formula:
Interest = (Principal)(rate)(time)
I = Prt
my understanding of this question is that $ 158,000 is the maturity level / future amount (F) so how do you find the principal without the Interest (I)?

A train leaves town A for town B, traveling at 35 mi/h. At
the same time, a second train leaves town B for town A at 45 mi/h. If the two towns
are 320 mi apart, how long will it take for the two trains to meet?

Ok, these problems are the worst for me. I would like to know how to arrive to the answer.
Would I do 35 divided into 320 and the same for 45?
The answers would be 9 and seven. Would I add those divide by two, and get 8?
This is really confusing, math is my worst subject, let alone word problems, any help would be greatly appreciated.

There are no leading zeroes. The sequence is:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, .etc., all the way to n. When you have finished, you will have written exactly n zeroes.

Find n. Here's a hint:

find arc legnth of curve
x=arcsint , y=ln sqrt(1-t^x)
- formula S b,a sqrt(f'(t)^2+g'(t)^2
- i got down to S0,1/2 1/x^2-1 if that is right but dont know what to do next.

Write integral for area of surface about the x-axis
x=(1/4)t^2 , y=t+2 , 0<=t<=4
- formula 2pi S a,b g(t) sqrt(dx/dt)^2+(dy/dt)^2
- about about half way and am stuck.

Please help fast as I will have to leave soon.
