Biology: Mitosis is the stage of cell division when the cell nucleus divides into two; cytokinesis is the stage when the whole cell divides into two. If you start with a single cell and it takes three minutes for cytokinesis to take place, how many cells are present after 30 min? b) If a cell mass contains 32768 cells, how long has it been undergoing cytokinesis? What constant must be added to each of the numbers, 60, 135, 285, for them to form a geometric sequence?
Investment: A five-year investment plan has the investor putting $2000 into GICs (Guaranteed Investment Certificates) at the beginning of each year for three years. The first GIC pays 6% per annum compounded semi-annually for five years, the second GIC pays 6.2% per annum compounded annually for four years, and the third GIC pays 6.25% per annum compounded monthly for three years. Determine the amount that the investment plan provides at the end of the five years.
