Consider a population of field mice p(t), where t is measured in days, that grows at a rate proportional to the current population, so that dpdt=r⁢p (a) find the rate constant r if the population triples in 30 days. (round the answer to four decimal places.)

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.
