A radioactive substance decays exponentially. A scientist begins with 130 milligrams of a radioactive substance. After 13 hours, 65 mg of the substance remains. How many milligrams will remain after 16 hours?

Apatient is given 50 mg dose of medicine the medicines effectiveness decreases every hour at a constant rate of 40% what is the exponential decay function that models this scenario how much medicine will be left in the patients system after 2 hours

With: label the vertices and all the elements needed. find x

Each of the walls of a room with square dimensions has been built with two pieces of sheetrock, a smaller one and a larger one. the length of all the smaller ones is the same and is stored in the variable small. similarly, the length of all the larger ones is the same and is stored in the variable large. write a single expression whose value is the total area of this room. do not use any method invocations.
