Sales of a product, under relatively stable market conditions but in the absence of promotional activities such as advertising, tend to decline at a constant yearly rate. This rate of sales decline...

1/2log6(9)-(3log6(X)+2log6(Y)) + 1/3log6(8) 6 is the log base

1. Use the properties of logarithms and transformations to describe how the graph of g(x)=ln(e^2x) 2. Simplify: log(1-1/x)-log(1+1/x) I need help with these two problems...

0.30 = log(x) 0.30 = ln(y) log(1.3)= ln(1.3)=

This problem involves the Rule of 70, which gives quick estimates of the doubling time of an exponentially growing quantity. If r% is the annual growth rate of the quantity, then the Rule of 70 says Doubling...
