In this case, w,(r) = 532(1-0.911e-00021.2466. Source: Canadian Journal of Animal Science. a. Where is this function increasing? b. Use a graphing calculator to graph this function with the function from the previous exercise on [0, 2000] by [0, 620]. C. Compare the two functions, indicating which type of cow grows the fastest and which type reaches the greatest weight. 60. Vectorial Capacity An organism (such as a mosquito) that carries pathogens from one host to another is called a vector. The vectorial capacity, defined as the capacity of the vector population to transmit the disease in terms of the potential num- ber of secondary inoculations originating per unit time from an infective person, is given by ma'p" In here m is the number of vectors per host, a is the number of od meals taken on a host per vector per day (biting rate), s the proportion of vectors surviving per day, and n is th th (in days) of the narnnit
