Find the difference in the weights of the largest land mammal, the male african elephant (1.4×104) and the largest sea mammal the blue whale (4.0×105).

The growth factor is A. 0.28 per decade.

Step-by-step explanation:

Step 1; It is given that the city grows by 28% per decade. Now we assign values to get a better understanding. If there were 1,000 people at the start of the decade there would be 1,000 + 28% at the end of the decade = 1000 + 280 = 1,280 at the end of the decade.

Step 2; To calculate the growth factor, we calculate the difference between the present value and the past value and divide it by the past value.

Growth factor = = = . So the growth factor is 0.28 per decade.
