(2) You've used a numerical method with second-order global error to estimate the value of a solution of a differential equation, and using 4 time steps you've got an error not exceeding 0.25. How many times must you halve the step size to be sure the error is less than 0.0001? How does the answer change if the method were fifth-order instead?

Just the answer. I just want to confirm if mine is correct.
Solve the problem completely and show the application of differential equation
"Suppose you are studying the growth of a bacteria population and you notice the rate of change of the population is equal to three times the number of bacteria present. Set up an ordinary differential equation for the number of bacteria and calculate the amount of time it will take for the population to double. Does the answer you found depend on the initial population y0 of the bacteria?" Need help solving problem above

A radioactive substance is decaying according to the formula y = Be-0.02t where y mg is the amount present t years from now. How long will it take for half the substance to decay? Round-off to the nearest integer.
Write a differential equation to model this physical situation. Snow is falling at a constant rate of 3/5 in per hour. It is being removed at a constant rate of 45% of the amount of snow on the ground per hour. If we use h(t) as the height of the snow at time t, and the removal of snow began at a height of 4 in --such that h(0)=4 --what would be the equation for the rate of change of the height as a function of time?
