Soon after taking an aspirin a patient has absorbed 300mg of the drug. if the amount of aspirin decays exponentially, with 150g remaining after 2hours:

a). determine an exponential function of the form y=a(b t)

that can be used to model the absorption of aspirin in the blood stream after t hours, in the above scenario.

b). using the model obtained in part (a) how much aspirin will be in the blood after 5.5 hrs.

c). using the model obtained in a) find to the nearest 0.1, the time it will take for the amount of aspirin in the bloodstream to decrease to 10mg?

Statement reason 1. δabc is similar to δced. given 2. 3. definition of slope 4. slope of slope of definition of slope 5. slope of × slope of multiplying the slopes 6. slope of × slope of substitution property of equality 7. slope of × slope of simplifying the right side the table contains the proof of the relationship between the slopes of two perpendicular lines. what is the reason for statement 2? a. parallel line segments that meet a common perpendicular line are proportional in length. b. the lengths of vertical and horizontal sides in congruent triangles are in a common ratio. c. trigonometric identities determine the lengths of the legs in a right triangle. d. corresponding side lengths in similar triangles are proportional in length.
