In an isolated environment, a disease spreads at a rate proportional to the product of the infected and non-infected populations. let i(t) denote the number of infected individuals. suppose that the total population is 2000, the proportionality constant is 0.0003, and that 1% of the population is infected at time t=0. write down the intial value problem and the solution i(t).

answer: the correct one is a

step-by-step explanation:

the correct is answer is a 9-sided polygon!

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

ratio is 2 : 9

the answer is three

13.5 : 3
