Find a cubic function with the given zeros. Square root of seven. , - Square root of seven. , -4
yan [13]

Answer:

y= x^{3} +4x^{2}-7x-28

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)

⇒ y = (x^{2} -7)(x +4)

⇒ y= x^{3} +4x^{2}-7x-28 (Answer)

Sunny_sXe [5.5K]
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 books are fictional how many are non fictional
adelina 88 [10]
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.
