8/8 would be 32 so 7/8 would be 28 because 8 x 4 = 32 which would make each eight equal four.
Answer:
-3/2
Step-by-step explanation:
Remeber, to find slope we use this formula:
y - y all over x - x, or (y-y) / (x-x)
(6-9) / (5-3)
-3 / 2
= -3/2
Answer:
1. S(1) = 1; S(n) = S(n-1) +n^2
2. see attached
3. neither
Step-by-step explanation:
1. The first step shows 1 square, so the first part of the recursive definition is ...
S(1) = 1
Each successive step has n^2 squares added to the number in the previous step. So, that part of the recursive definition is ...
S(n) = S(n-1) +n^2

2. See the attachment for a graph.
__
3. The recursive relation for an arithmetic function is of the form ...
S(n) = S(n-1) +k . . . . . for k = some constant
The recursive relation for a geometric function is of the form ...
S(n) = k·S(n-1) . . . . . . for k = some constant
The above recursive relation is not in either of these forms, so it is neither geometric nor arithmetic.
Answer:
the answer is C) 7 and -7
Step-by-step explanation:
A. The maximum profit is when : P` ( x ) = 0
P` ( x ) = ( - 0.15 x²+ 600 x - 140,500 ) `
P` ( x ) = - 0.3 x + 600
- 0.3 x + 600 = 0
0.3 x = 600
x = 600 : 0.3 = 2,000
Answer: 2000 units must be sold on a monthly basis to maximize the profit.
b. P max = - 0.15 · 2000² + 600 · 2000 - 140,500 =
= - 600,000 + 1,200,000 - 140,500 = $459,500
Answer: The maximum profit is $459,500.
