Imagine that the climate on an island is expected to change over time. Scientists want to determine how the change will affect the animals on the island. They create a computer model that considers all the factors that will change. What is most likely true about the computer model?
A. It will be useless because there would be too many factors
B. It will allow the scientists to stop the climate from changing
C. It will help the scientists predict likely changes to the animals
D. It will provide exact information about the future of the island

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)

The radioactive isotope of lead, pb-209, decays at a rate proportional to the amount present at time t and has a half-life of 3.3 hours. if 1 gram of this isotope is present initially, how long will it take for 80% of the lead to decay? (round your answer to two decimal places.)
