an example would be: y=x(2x+5) but the parenthesis would be the absolute value

This is the problem:
x(x^2+1)(x-2)/(x-1)(x+1) > (or equal to)0

These are the answers I got:
x<-1
0<(or equal to)x<1
x>(or equal to)2

an owner's share of a business is $32,500. The business has grown at a rate of 7% APR compounded quarterly for the last 5 years 3 months. What was the owner's share worth 5 years 3 months ago?

it gives the equation [ A = P (1 + r/n ) ^nt ]

can anyone show me how to do this? I'd really appreciate it.

if a man was born on the 1st of january on the year after a leap year, and he is a million days old, how old is he in years?

you must take into account the extra days from leap years, because im pretty sure that he may be over 1000 years old

It is a five-digit number.

If you place a 1 on the right of a five-digit number, the six digit number that is formed is 3 times the number formed when you place a 1 on the left of the five-digit number.

I am doing a Binominal Distribution. On column A I will put a list of number from 0 to 50 (do I have to type in the number in every cell or is there anyway to do it automatically?). In column B I will put the formular BINOMDIST(x,n,p,false). N and p is already known. Now I want each cell in column B to automatically take the number in the nearby cell in column A as the x value in the formular. How can I do this without copying the formular 50 times and change each A2 to A3...

Thanks a lot!!
