The bones of a newly discovered dinosaur weigh 170 pounds and measure toet, with a 6-inch claw on one tre douch hind foot The age of the dinosaur was estimated using a radioactive staturen dating of nois surrounding the bones Complete parts and be The radioactive substance decays exponentially with a hartite of approximately 1.24 bilion years. Use the fact that ata 1.2 bilion years a pier amant of the radioactive sitaterce we have decayed to hat de arginal amount to show that the decay model for the radioactive substance is given by A-AJE - where is in billions of years To show that the decay model for the radioactive substance is An Apr 0.5589 find the decay rate for a substance. Substhe the values of A and t in the exponertial decay model Ao Ages A-AH Substitute Divide both sides of the equation by A Take the natural logarithm on both sides and simply Solve for (Round to five decimal places as needed) Analysis of the rocks surrounding the dinosaur bones indicated that of the original amount of radioactve substance was a part at A0254in the model in partial and estimates of bones of dinosaur The estimated age of these dinosaur bones is about bilion years. Round to four decimal places as needed A7 Ext Honorlack .
