1At the beginning of 1995, an investor decided to invest £6 000 in a plan that grew at an average rate of 6% per year. Show that, if this percentage rate of increase is maintained for 10 years, the value of the original investment will be about £10 745.

2A population of bacteria is growing exponentially. Explain briefly what this means, using a sketch graph to illustrate your answer.

(i) At timethours, the size,P, of the population of bacteria is given byP= 1000 (2.8)^0.02t. State the value ofPwhent= 0. Find the value oftwhen the size of the population is twice its initial value.

(ii) A second population of bacteria doubles in size every 12 hours. Find the number of hours it takes for this population to increase in size by a factor of 100.
