To test an individual's use of a certain mineral, a researcher injects a small amount of a radioactive form of that mineral into the person's bloodstream The mineral remaining in the bloodstream is measured each day for several days Suppose the amount of the mineral remaining in the bloodstream (in milligrams per cubic centimeter)t days after the initial injection is approximated by C(t) = 5(21+3) 3 1/2 Find and interpret the rate of change of the mineral level with respect to time for (a) O days, (b) 4 days, and (c) 7.5 days. (d) Are the slopes of the tangent lines to C always positive or always negative? What does this indicate about the rate of change of the mineral level? (a) The rate of change of the mineral level with respect to time for 0 days is (Round to two decimal places as needed.) milligrams per cubic centimeter per day
