Question 981053: Hi appreciated math tutors.
I am not sure how to solve the following problem, it reads:
A piece of notebook paper is about .0032 inch thick. If you begin with a stack consisting of a single sheet and double the stack 25 times, how tall will the stack be in inches? HINT: Write and solve an exponential equation to find the height of the stack in inches.
I tried to solve the problem by multiplying .0032 by two and raising this product to the 25th power, but it comes out to be a very small negative number. Of curse, a negative answer is not correct. Please demonstrate how to solve and if an inverse is taken, please explain why if possible. Thank you!

Question 982696: quantitative comparison
t is an integer
COl A: 1/1+2^t
COL B: 1/1+3^t
Is it correct to say you cannot determine which is larger without additional information.
My reasoning is if t is positive, the col a is larger. and if t is negative, the col b is larger.
Is this correct? Am I missing anything? Please explain. Thanks! :)
