K Briefly explain how repeated doublings characterize exponential growth. Describe the impact of doublings, using the wheat on the chessboard or magic penny parable. Select the correct choices that complete the sentences below. In repeated doublings, every time the amount will be of what it has previously. The percentage growth will be % every time. Therefore, in repeated doublings, the amount increases by some percentage of its previous value. Hence, repeated doubling is a case of growth. For explaining the impact of doublings, consider the chessboard parable. If a chessboard were to have wheat placed upon each square such that one grain were placed on the first square, two on the second, four on the third, and so on (doubling the number of grains on each subsequent square), the sum of grains on all 64 squares is 1+2+4+8+ and so forth for the 64 squares. The total number of grains is on on on
