[hllt time I: 2 years, use a derivative to estimate how much the value will change within the next year. [a] The value of the ccmputerE years alter purchase is $|:|. To test an individual's use of a certain mineral, a researcher injeds small amount ofa radioactive torm ofthat mineral into the person's bloodstream. The mineral remaining in the bloodstream is measured each day tor several days. Suppose the amount of the mineral remaining in the bloodstream {in milligrams per cubic 1 1 _ centimeter} tdays after the initial injection is approximated by C(t} = 5(6t+2]l 2 . Find the rate of change C with respect to time for each of the given number ot days. Complete parts (a) through {d} below. [a]t=U At t = i], the rate of change of the mineral level with respect to time is approximately I: milligrams per cubic centimeter per day. (Round to four decimal places as needed.)
