The incidence (number of new cases/day) of a contagious disease spreading in a population of m people is given by i(x) = kx(m − x), where k is a positive constant and x denotes the number of people already infected. find the percentage of the population infected such that the incidence is a maximum.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
