The number f of bacteria in a petri dish during an experiment can be modeled by the function f(t)=5(2)^t, where t is time, in seconds, since the experiment began. find and interpret the average rate of change on the interval of [0,5]

Ascientist has 50 grams of a radioactive element. the amount of radioactive element remaining after t days can be determined using the equation (1) after two days the scientist receives a second shipment of 50 grams of the same element. the equation used to represent the amount of shipment 2 remaining after t days is 10) - 50 which of the following is an equivalent form of the expression for the amount remaining in shipment 2? what’s the answer?
