In this unit we look at the graphs of exponential and logarithm functions, and see how they are related. Use property of exponential functions a x / a y = a x - y and simplify 110/100 to rewrite the above equation as follows e 0.013 t'- 0.008 t' = 1.1 Simplify the exponent in the left side e 0.005 t' = 1.1 Rewrite the above in logarithmic form (or take the ln of both sides) to obtain 0.005 t' = ln 1.1 Solve for t' and round the answer to the nearest unit.
