40, Brain weight B as a function of body weight W in fish has been modeled by the power function B 0.007W², where B and W are measured in grams. A model for body weight as a function of body length L (measured in centimeters) is W=0.12225. If, over 10 million years, the average length o a certain species of fish evolved from 15 cm to 20 cm at a constant rate, how fast was this species brain growing when the average length was 18 cm?

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.

The exponential growth model of a population in a certain city is A= 20e0.05t, where A is the size of the population in thousands in a particular year, and t is the number of years from the year 2000. a) What is the population of the city in the year 2000? b) What is the population of the city in the year 2020? C) If the rate of change increased after 2020 to 10%, in what year that the population be 200,000? d) What could be the initial population if the number of people is 10, 0000, 000 in 12 years with the same growth rate?
