Answer: B or the second choice
Step-by-step explanation:
well for triangle DEF since E is on the top left, it should be on the bottom right. While F was on the bottom right, it would be on the top left where E originally was. The angles inside has the same situation with E and F, however D stills stays at the top because when reflected like a mirror, D stays at the top. Sorry it’s long and hope this helps!
PS u also took a pic of the correct answer lol XD
Answer:

Step-by-step explanation:
the difference is -5
- nth=a+(n-1)d
- a=253,n=49,d=5
- 253+(49-1)×-5
- 253+48×-5
- 253+(-240)
- 253-240=13
the 49th term is 13

Beginning with the last deposit and working toward the present, the amount in the account is
3000 + 3000*1.06 + 3000*1.06^2 + 3000*1.06^3 + 3000*1.06^4
= 3000*(1.06^5 -1)/(1.06 -1)
= 16,911.28 . . . dollars
_____
The sum is found using the formula for the sum of a geometric series. For first term a1 and common ratio r, that sum is
Sn = a1*(r^n -1)/(r -1)
Your series has a1=3000 and r = 1.06. It has 5 terms (n=5).
