Biomedical: Drug Sensitivity (63 continued) For the reaction function given in Exercise 63, find the dose at which the sensitivity is 25. [Hint: On a graphing calculator, enter the reaction function , and use NDERIV to define y₂ to be the derivative of y₁. Then graph y₂ on the window [0, 140] by [0, 50] and TRACE along y₂ to find the x-coordinate (rounded to the nearest whole number) at which the y-coordinate is 25. You may have to ZOOM IN to find the correct x-value.]

Biomedical: Drug Sensitivity The strength of a patient’s reaction to a dose of x milligrams of a certain drug is . The derivative R’(x) is called the sensitivity to the drug. Find R’(50), the sensitivity to a dose of 50 mg.
