- Use the total differential to approximate each quantity. Then use a calculator to approximate the quantity, and give the absolute value of the differences in the two results to 4decimal places. 0.98e0.04.arrow_forwardPlant Growth Researchers have found that the probability P that a plant will grow to radius R can be described by the differential equation dPdR=4DRP2 where D is the density of the plants in an area. Source: Ecology. Given the initial condition P(0)=1, find a formula for P in term of R.arrow_forwardFlea Beetles A study of flea beetles found that the change in the rate of flea beetles moving in and out of a patch of beetles could be described by the differential equation dNdt=mN+i where N is the number of beetles in a patch, m is the rate at which beetles move out of the patch, and i is the rate at which they move in. Source: Ecological Monographs. a. Solve the differential equation above with the initial condition N(0)=N0. b. After the researchers cleared a patch of beetles, so that N0, they would return 8 hours later and count the number of beetles. Show that the parameter i can then be estimated by the equation i=mN(8)e8m1 c. The researchers estimated m using the equation m=lnFsd, where Fsd is the fraction of beetles who remained in the patch in which they were released. For the beetles P, striolata released in July in the lush interior of patches 5 meters apart, the average values of Fsd and N(8) were 0.709 and 4.5, respectively. Find the values of m and i.arrow_forward
