One method of slowing the growth of an insect population without using pesticides is to introduce into the population a number of sterile males that mate with fertile females but produce no offspring. let p represent the number of female insects in a population and s the number of sterile males introduced each generation. let r be the per capita rate of production of females by females, provided their chosen mate is not sterile. then the female population is related to time t by t = p + s p[(r − 1)p − s] dp. suppose an insect population with 10,000 females grows at a rate of r = 1.2 and 400 sterile males are added. evaluate the integral to give an equation relating the female population to time. (note that the resulting equation can't be solved explicitly for p. remember to use absolute values where appropriate.)

Based on the graph, what is the dependent variable, the equation relating the two variables, and how far will the dragonfly travel in 24 hours if it continues to fly at the same speed? (look at the image below)The dependent variable is distance, the equation is x = 20y, and the dragonfly will travel 360 miles. The dependent variable is distance, the equation is y = 20x, and the dragonfly will travel 480 miles. The dependent variable is time, the equation is x = 20y, and the dragonfly will travel 360 miles. The dependent variable is time, the equation is y = 20x, and the dragonfly will travel 480 miles.

A shipping company charges a flat rate of $7 for packages weighing five pounds or less, $15 for packages weighing more than five pounds but less than ten pounds, and $22 for packages weighing more than ten pounds. During one hour, the company had 13 packages that totaled $168. The number of packages weighing five pounds or less was three more than those weighing more than ten pounds. The system of equations below represents the situation.s+m+l=137s+15m+22l=168s-l=3Which matrix can be used to show the number of packages in the different weight classes during that hour?
