the answer

The formula t= -[ In A - In (A - N)] describes the time, t, in weeks, that it takes to achieve mastery of a portion of a task, where A is the maximum learning possible, N is the portion of the learning that is to be achieved, and c is a constant used to measure an individual's learning style. a. Express the formula so that the expression in brackets is written as a single logarithm. b. Use the form of the formula from part (a) to answer this question. An animal learning sign language can master a maximum of 60 signs. How many weeks will it take the animal to master 25 signs if the constant c for that animal is 0.02? . . . a. Express the formula in the brackets as a single logarithm. t= (Use parentheses to clearly denote the argument of each function.)
