The average score S(t), as percent, after t months was found to be given by the function: S(t) = 78-15 log(t+1), t≥0 (a) What was the average score when the sudents initially took the test, t=0? (b) What was the average score after 4 months? 3. Convert to a logarithmic equation: 5x = 251 A. log 5 251 = B. log 251 = 5 C. log 5 = 251 D. log 5 = 251 4. Solve the equation. Check all proposed solutions. √ + 4 + 2 = 5. Simplify: (a) log 8 1 = (b) log 5 6. Let f (x) = e 1 625 x+1 =-3
