Answer

Final Answer: The function of y in terms of x is \(\boxed{y = 20Cx}\)

Steps

Step 1 :Given the equation in logarithmic form: \(\ln y=\ln 20x+\ln C\)

Step 2 :Using the property of logarithms that states that \(\ln(a*b) = \ln(a) + \ln(b)\), we can combine the terms on the right side of the equation: \(\ln y=\ln (20xC)\)

Step 3 :Converting the equation into exponential form using the property that if \(\ln(a) = b\), then \(a = e^b\), we get: \(y = 20Cx\)

Step 4 :Final Answer: The function of y in terms of x is \(\boxed{y = 20Cx}\)
