SOCial SCi 3..348 55 Question Help a Pharmaceutical rms invest signicant money in testing any new medication. After the drug is approved for use, it still takes time for physicians to fully accept and start prescribing the medication. The acceptance by physicians approaches a limiting value of 100%, or 1, after time t, in months. Suppose that the percentage P of physicians prescribing a new cancer medication is approximated by the equation below. Complete parts (a) through (c). P(t)=100(1- e '0'\") a) What percentage of doctors are prescribing the medication after 3 months? El% (Do not round until the nal answer. Then round to the nearest tenth as needed.) \"hys Sci 3.4.9 A chemical substance has a decay rate of 9.3% per day. The rate of change of an amount N of the chemical is given by the equation dN = 0.093 N dt where t is the number of days since decay began. Complete parts a) through c). a) Let No represent the amount of the chemical substance at t = 0. Find the exponential function that models the situation.
