Question

A chemical compound decays at a rate of 5% per year. If the initial size of the compound is 100 grams, what is the exponential function that represents the rate of decay? (1 point) Responses y=0.95x0.05 y is equal to 0 point 9 5 x raised to the 0 point 0 5 power y=100x0.95 y is equal to 100 x raised to the 0 point 9 5 power y=100x0.05 y is equal to 100 x raised to the 0 point 0 5 power y=100(0.05)x y is equal to 100 times 0 point 0 5 to the x th power y=100(0.95)x y is equal to 100 times 0 point 9 5 to the x th power

Answer 1

y = 100(0.95)^x

This equation represents the exponential function that represents the rate of decay of the compound. The initial size of the compound is 100 grams, and it decays at a rate of 5% per year.
