1. Scientists have observed that living matter contains, in addition to carbon, C 12, a fixed Percentage of a radioactive isotope of carbon, C14. When the living material dies, the amount of C12 present...

Ray Idusties bought a touch screen monitor for $850. The monitor is expected to depreciate at a rate of 35% per year. What will the value of the monitor be in 5 years?

(a) What is the exponential decay rate? Round to 5 decimal Places (b) Suppose we have 20 mg sample. How much of the sample will remain after 3000 years? Round to two decimal places

I don't know what exact formula to use. i know 5% is .05 and 7 years is the Time. I'm not sure how to find the half time in years with the given.

Exponential growth or decay? Write a function that represents this situation: Initial Amount = ?? Growth\Decay Rate: Percent=?% Decimel=?.? Answer:

what is the percentage of decay for the years
