I am dealing with Interest Compounded Continuosly. I am looking for the balance after 10 years. The book shows that P(10) = 2oooe^0.08(10) = 2000e^0.8 = $4451.08 My questions is how do you calculate 2000e^o.8 and end up with 4451.08?

Solve X + 1/x – 2 ≥ 3 I know you have to subtract the 3 from both sides to get the zero on right of the inequality sign. I don't understand how to make one fraction after I do this.

I'm working on vertical asymptotes when factoring 6x^2 - 6 (denominator). I came up with 6(x^2-1). Then I was trying to find the zeros of the denominator but 6 does not = 0 and x^2-1=0 then I got x^2=1 and x = plus or minus sqrt 1. Can you tell me what I am doing wrong?
