## logarithmic functions word problems | Free Math Help Forum

Logarithm word problems are a constant in the study of Chemistry and Earth Science. The scale that measures how acidic or basic a substance is based on the logarithmic scale to measure the concentration of hydrogen ion in a solution. Oct 13,  · Do you know how to solve basic logarithmic and exponential equations, so you only need some word-problem examples? Or do you need to start back with logs and exponential functions? Or with functions, graphing, and solving in general? (In all cases, a search engine would likely be useful. When asked to solve a logarithmic equation such as or the first thing we need to decide is how to solve the problem. Some logarithmic problems are solved by simply dropping the logarithms while others are solved by rewriting the logarithmic problem in exponential form.

If someone could tell me how to do them and the answers, how to solve logarithmic word problems, that would be great. Year World Population billions 2. Predict when the population will reach 10 billion.

The chemical by-products of creating the drug are a big environmental hazard, and toxic spill cleanup crews are often called in to clean up abandoned meth labs.

The table below shows the number of meth labs how to solve logarithmic word problems by toxic spill crews in Washington State alone. Year World Population billions 42 a Find an equation for "f. Assume there are 2. Assume that a bacterium divides into two bacteria every hour, on average.

Let f t represent the number of bacteria in millions on the peach at "t" hours after Tuesday noon. We assume that the caffeine enters his bloodstream immediately, and that there was no caffeine in his bloodstream prior to drinking the cofee. The half-life of caffeine in a person's bloodstream is about 6 hours. A cup of coffee contains about milligrams of caffeine.

Find an equation for "f. Use "f" to predict the amount of how to solve logarithmic word problems in his bloodstream when he goes to bed. How much caffeine will be in his bloodstream from these 2 2 cups of coffee just after drinking the second cup? Explain how you can find this result without using an equation.
