An ancient artifact was recently discovered, but due to rust and corrosion, only 75 grams of the original item remained. based on historical dates, scientists believe that this artifact was decaying at a rate of 2% each year. although the artifact will now be preserved at a museum, scientists wonder: how much of the original artifact would there be if they had not discovered it for another 10 years?
write an exponential function rule and solve. round your answer to the nearest whole number (the ones place). enter both the number and the associated units

namely, what is the leftover amount when the decay rate is 2% for an original amount of 75 grams after 10 years?

Answer with explanation:

The exponential decay function is written as :-

, where f (x) is the amount of material left after x years , A is the initial amount of material and r is the rate of decay.

Given : The amount of original item remained now = 75 grams

The rate of decay = 2% = 0.02

Now, the amount of original artifact would there be left if they had not discovered it for another 10 years is given by :-

Solving the above exponential equation , we get

Hence only 61 grams original artifact would there be left if they had not discovered it for another 10 years .

answer: 4/6 =5/7.5

step-by-step explanation: it is based on scale and the scale between the two is 1.25. the answer is correct but i dont know if i explained it right
