One type of uranium has a daily radioactive decay rate of 0.4%. If 30 pounds of this uranium is available today, find out how much will still remain after 50 days? Use y=30(0.996)^x and let x be 50 days. | The quantity left after 50 days is 24.6 pounds of uranium |
Is y=2^x an exponential growth or decay? | Exponential Growth |
Is y=(1/2)^x an exponential growth or decay? | Exponential Decay |
Is this an exponential growth of decay function? y=a(1-r)^t? | Exponential Decay due to the subtraction sign. |
