WORKED TASK ONE
A fictional amount begins at 240 units and halves every three hours. Calculate the modeled amount at nine hours and the time to reach 60 units. Express the remaining fraction using a power of two, check the time with logarithms, and state what the model does not verify.

WORKED TASK TWO
A supplied inverse-square model has y = 80 units at x = 2 m. Calculate y at 4 m and 6 m. A generated answer says doubling distance doubles the output to 160 units. Identify its relationship error and verify your correction using the constant yx².
