In this Loom, I'll be going over problems 26 through 35 of the semester two practice test. We'll be matching differential equations to their slope field graphs and solving for the half-life of radioactive elements. For the differential equations, we'll be looking for where the slope is equal to zero and using that to match the graph. As for the radioactive decay problems, we'll be using the half-life formula to solve for the yearly decay rate or the original amount. Don't worry, I'll walk you through each step and show you how to use the natural logarithm to undo the exponential. So grab a calculator and let's get started!"}
