Suppose that C is the concentration of a drug in the bloodstream t hours after the...

Suppose that C is the concentration of a drug in the bloodstream t hours after the initial dose is administered. Suppose the initial dose Co was 191.8 µg / mL and suppose that 189 µg / mL is administered every hour. If the body metabolizes and eliminates 35% of the concentration of drug C; in a period of one hour; determine C2, the concentration of the drug in the bloodstream two hours after the initial dose is administered.

Suppose Ct is the concentration of a drug in the bloodstream t hours after the initial dose is administered. Suppose the initial dose C2was 217.6 ug/mL and suppose that every hour is administered 174 g/mL. If the body metabolizes and eliminates 54% of the concentration of the drug Ct over a period of one hour; determine C2, the concentration of the drug in the bloodstream two hours after the initial dose is administered. Response at two decimal valors.

A drug response curve describes the level of medication in the bloodstream after a drug is administered. A surge function S(t) = Atpe−kt (where t > 0) is often used to model the response curve, reflecting an initial surge in the drug level and then a more gradual decline. If, for a particular drug, A = 0.03, p = 4, k = 0.06, and t is measured in minutes, estimate the times t corresponding to the inflection points. (Round your...

A curve c is defined by the parametric equations x= t^2 y= t^3-4t a) The curve C has 2 tangent lines at the point (6,0). Find their equations. b) Find the points on C where the tangent line is vertical and where it is horizontal.

The position of an object is given by s(t)=2cos(4t−8)−7sin(t−2)s(t)=2cos⁡(4t−8)−7sin⁡(t−2) . Note that a negative position here...

The position of an object is given by s(t)=2cos(4t−8)−7sin(t−2)s(t)=2cos⁡(4t−8)−7sin⁡(t−2) . Note that a negative position here simply means that the position is to the left of the “zero position” and is perfectly acceptable. Answer each of the following questions. Compute (accurate to at least 8 decimal places) the average velocity of the object between t=2t=2 and the following values of tt. Make sure your calculator is set to radians for the computations (i) 2.5 (ii) 2.1 (iii)2.01 (iv)2.001 (v) 2.0001...
