Find out from your instructor how to submit your calculator screens. b) What does your model predict would have been the amount present at 5 minutes? c) At what time would 25.1 grams be produced, according to your model? d) Are the products formed at a constant rate over time? Explain.

Best ResponseYou've already chosen the best response.5my calculator gives below equation for part \(a\) : \[y = 2.43*(1.16)^x\] you should also get something close to that

Best ResponseYou've already chosen the best response.0Many wildlife populations are monitored by taking aerial photographs. Information about the number of animals and their whereabouts is important to protecting certain species and to ensuring the safety of surrounding human populations. In addition, it is sometimes possible to monitor certain characteristics of the animals. The length of an alligator can be estimated quite accurately from aerial photographs or from a boat. However, the alligator's weight is much more difficult to determine. In the example below, data on the length (in inches) and weight (in pounds) of alligators captured in central Florida are given. Develop a model from which the weight of an alligator can be predicted from its length.
