Answer:
Step-by-step explanation:
We are given the recursive formula:
This is the recursive formula for an arithmetic sequence.
The explicit formula for an arithmetic sequence is given by:
Where d=3 is the common difference.
We plug in this values to get:
We now expand and simplify to get:
We simplify to obtain:
Answer:
B. 3, 3, 2
Step-by-step explanation:
The triangle inequality requires the sum of the lengths of the two shortest sides exceed the length of the longest side. That is the case only for the lengths of selection B:
2 + 3 > 3
When reflecting about the y axis, you x coordinate changes sign, so your answer would be D) (-2;-4)
The second answer is D) (the bottom right one)
Answer:
C) 0
Step-by-step explanation:
-2+2=0
No. Amelia wouldn't be able to go three weeks without getting the notification.
3×7=21
300÷15=20 means that in twenty days time, Amelia will have withdrawn ALL of her money.
That time period doesn't allow for Amelia to even reach the last day of the third week (21 days).
