Cowling's Rule is a method for calculating pediatric drug dosages. If a denotes the adult dosage (in milligrams) and if t is the child's age (in years), then the child's dosage is given by D(t) = t + 1 24 a. (a) Show that D is a linear function of t. Hint: Think of D(t) as having the form D(t) = mt + b. What are the slope m and the y-intercept b?
