Answer:
(a) O(x²)
(b) O(x²)
(c) O(x²)
(d) Not O(x²)
Step-by-step explanation:
If a function is O(x²), then the highest power of x in the function ia greater or equal to 2.
(a) 100x + 1000
This is O(x), not O(x²)
(b) 100x² + 1000
This is O(x²)
(c) x³.100 − 1000x²
This is O(x²)
(d) x log x²
This is not O(x²)
Answer:
See below in bold.
Step-by-step explanation:
Factored form:
f(x) = -5(x + 7)(x - 9)
Standard form:
f(x) = -5(x^2 + 7x - 9x - 63)
f(x) = -5(x^2 - 2x - 63)
f(x) = -5x^2 + 10x + 315.
No, the number of cows in the barn is 27. You can get this number by subtracting the 83 cows he has from the 56 that are out of the barn.
83 - 56 = 27
