Write a recursive expression
When n = 1
When n = 2
can be rewritten as
Substitute 3 for f(1)
Express 1 as 2 - 1
----- (1)
When n = 3
can be rewritten as
Substitute 8 for f(2)
Express 2 as 3 - 1
------ (2)
Write out (1) and (2)
Replace 2 and 3 with n in both cases; This gives
Hence;
The recursive is
To find n
1. Subtract 8n from both side to get -3n=30
2. Divide both sides by -3 to get n=-10
Answer:
Hope this helps!
Step-by-step explanation:
1- -24
2- -23
3- -2
4- 11
5- 5
6- -3
7- 28
8- 120
Selections B and D both appear to be appropriate.
B) (x+8)² + (y+5)² = 13
D) (x+8)² + (y+5)² = 13
_____
The center is at the midpoint of the diameter, ((-10-6)/2, (-8-2)/2) = (-8, -5). For center (h, k) and radius r, the equation is
(x -h)² +(y -k)² = r²
(x -(-8))² +(y -(-5))² = (√13)²
(x+8)² + (y+5)² = 13
