Use the given information to write an equation for \(y .\) Confirm your result analytically by showing that the function satisfies the equation \(d y / d t=C y .\) Does the function represent exponential growth or exponential decay? $$ \frac{d y}{d t}=-\frac{2}{3} y, \quad y=20 \text { when } t=0 $$
Write the expression as the logarithm of a single quantity. $$ \frac{1}{3} \ln (x+1)-\frac{2}{3} \ln (x-1) $$
Solve for \(x\) or \(t\) $$ 400 e^{-0.0174 t}=1000 $$
Write the expression as the logarithm of a single quantity. $$ \ln (2 x+1)+\ln (2 x-1) $$
Solve for \(x\) or \(t\) $$ 2^{1-x}=6 $$
