Answer:
Step-by-step explanation:
We have to find a cubic function of x whose zeros are at x = √7, x = -√7 and at x = -4.
Therefore, the factors of the function will be (x - √7), (x + √7), and (x + 4)
Hence, the equation will be y = (x - √7) (x + √7) (x + 4)

The most likely thing that has happened in this case is that a fee is paid for the registration.
The function that best models this problem is:
y = 45x + 15
Where,
x: number of months.
Y: payment of each month.
For the first month we have:
y = 45 (1) +15
y = 45 + 15
y = 60
answer:
the most likely reason for the bill being this amount is
registration fee.

55 percent of 120 is 66.
120 - 54 = 66.
66 Books are fictional
So that being said, the other part of your remaining total is 54. 54 books are non-fictional. (The above where I said 120-54). Since 120 - 66 = 54.
