2a- enlargement
3a- reduction
4a- enlargement
Step-by-step explanation:
when the scale factor is greater than 100% it is making it larger, when less than 100% size it is making it smaller. for every answer do the original number (ex #1 would be 48 inches) and multiply it by the scale factor in decimal form, by moving the decimal over two places (ex #1 the 25% would become .25 or 1/4). therefore #1 would be an equation like 48 x 0.25= 12
Chenoa starts with $250 in her saving account and each month she adds $15 in her saving account.
Therefore, we obtain a sequence as:
250, (250+15), (250+15+15),...
250, 265, 280,....
So, we get the first term (
) as 250.
Now , we can clearly observe that the first term is 250 and second term is obtained by adding 15 to the first term that is 265 and so on.
Similarly in an arithmetic progression, last term is 
and its previous term is 
.
Similarly, will be obtained by adding 15 to its previous term .
So, 
and =250.
Therefore, Option C is correct.
