In a certain country, the number of people who drive electric vehicles can be modeled bythe functionP (t) = 31.8+ 20.6 ln (5t2 +5.3)where P(t) gives the estimated number of drivers as a percentage of the population, and t isthe time in years (t = 0 corresponds to 2020). How fast is this percentage expected to beincreasing in the year 2025?About 13.5%About 7.9% per year.About 15.8% per year.About 3.8% per year.

Given is the modeled function P(t)=31.8+20.6ln5t2+5.3 We need to find how fast is the percentage…

Suppose a species of fish in a particular lake has a population that is modeled bythe logistic population model with growth rate k, carrying capacity N, and time tmeasured in years. Adjust the model to account for each of the following situations. * One hundred fish are harvested each year.* One-third of the fish population is harvested annually.* The number of fish harvested each year is proportional to the square root of thenumber of fish in the lake. I was hoping to compare my answer to yours because I am a little confused if I did it right. Thank you for your time and effort.
