Fill in the blank so that the resulting statement is true. If log 5x + log 5(x + 2) = 2, then log 5 = 2 If log 5X + log 5(x + 2) = 2, then log 5 = 2. Rewrite the equation in terms of base e. Express the answer in terms of a natural logarithm and then round to three decimal places.. y = 94(3.5)* Express the answer in terms of a natural...

This exercise uses the population growth model. The population of the world was 7.1 billion in 2013, and the observed relative growth rate was 1.1% per year. (a) Estimate how long it takes the population to double. (Round your answer to two decimal places.) yr (b) Estimate how long it takes the population to triple. (Round your answer to two decimal places.) yr
