The population of viruses in an influenza culture after t hours is given by the function x(t)=5e^t/4.6 The cost y in dollars for a new automated microscope to count x viruses in a sample is y(x)=In 9x create the composite function that calculates the cost y in dollars of counting the number of viruses in an influential culture after t hours
sin y(x) = ln 9x,
y(x(t)) = ln 9x(t) = ln(9*5e^(t/4.6))
= ln(9*5) + ln(e^(t/4.6))
= ln45 + t/4.6
