Answer:
Hello,
<u>k=-3 and h=-2</u>
Step-by-step explanation:
h+1 is thus a root of x²+(-3-1)*x-5=0
x²-4x-5=0
x²+x-5x-5=0
x(x+1)-5(x+1)=0
(x+1)(x-5)=0
h+1=-1
<u>h=-2</u>

Answer:
- Recursive formula:
Explanation:
All the shown formulae in the choice list are recursive formulae instead of explicit formulae.
Explicit formulae that represent arithmetic sequences are of the form:
That kind of formula permits to determine any term knowing the first term, the number of the term searched, and the common difference (d).
On the other hand, the recursive formulae let you to calculate one term knowing the previous term and the difference.
In this case, the difference in the number of squares of two consecutive terms is:
- differece = number of squares in the second layer - number of squares in the first layer.
- d = 10 - 5 = 5
Then, the recursive formula is:
Answer:
Step-by-step explanation:
Let, the number of blueberry slices = b and number of cherry slices = c.
As, each slice sells for the price of $3.50.
Thus, the revenue of total slices sold =
Also, the money spent on ingredients of both the pie is $15.25 and $12.84 respectively.
Thus, the total selling cost of the slices = $15.25 + $12.84 = $28.09.
So, we have,
Cindy's profit = Revenue - Cost
i.e. Cindy's profit =
Hence, the required expression is .
