Answer:
<em>6, 10 and 8</em>
Step-by-step explanation:
Given the recursive function an = an-1-(an-2 - 4), when a5 =-2 and a6 = 0?
a6 = a5 - (a4 - 4)
0 = -2 - (14 - 4)
2 = - (a4 - 4)
-2 = a4 - 4
a4 = -2 + 4
a4 = 2
a5 = a4 - (a3 - 4)
-2 = 2 - (a3 - 4)
-2-2 = - (a3 - 4)
-4 = -(a3 - 4)
4 = a3 - 4
a3 = 4+4
a3 = 8
Also
a4 = a3 - (a2 - 4)
2 = 8 - (a2 - 4)
2-8 = - (a2 - 4)
-6 = -(a2 - 4)
6 = a2 - 4
a2 = 6+4
a2 = 10
a3 = a2 - (a1 - 4)
8 = 10 - (a1 - 4)
8-10 = - (a1 - 4)
-2 = -(a1 - 4)
2 = a1 - 4
a1 = 2+4
a1 = 6
<em>Hence the first 3 terms are 6, 10 and 8</em>
Answer: Stop and Save is better
Step-by-step explanation:
you can get 3 apple at Quick market for $1.20, but you can buy 5 at Stop and Save for only 5 cents more, plus your getting two more apples.
Solve the following: $10 = $7.03(1.03)^t for t.
log 10 - log 7.03 = tlog 1.03. Solve for t.
1 - 0.847
---------------- = t = 11.77 years (answer)
0.013
