please can I get help on these questions

6. Suppose that we cook a chicken whose initial temperature is 32 F to a temperature of 165 F over the course of thirty minutes in an oven with temperature a of 400 F. Approximate the constant of proportionality using Newton's Law of Cooling. A. k = 0.016 B. k = 0.014 C. k = 0.015 D. None of the above 7. In Section 2.5.4, we learn that the differential equation for falling objects with air resistance is given by, U't - 0 = -g m where k > 0 is the drag coefficient, m is the mass of the object in free fall, and g is the gravitational acceleration. What type of differential equation is this and what is the general solution? A. This is a linear differential equation, and we find v = Cem _ gm B. This is a linear differential equation, and we find v - Ce ma_ gm k C. This is a linear differential equation, and we find v = Cem D. None of the above 8. Determine the intrinsic growth rate of an environment with a carrying capacity of 100,000 if the initial population is 50, and the population if 2,000 after 3 years. A. k = 6.57:10-8 B. k = 6.57 C. k = -6.57x10-8 D. None of the above
