Given:
Degree of a polynomial is 7.
To find:
The possible combination of root types for a 7th degree polynomial.
Solution:
We know that, by complex conjugate root theorem, is a complex number is a root of a polynomial, then its conjugate is also the root of that polynomial, it means number of complex roots always an even number.
Similarly,
Irrational roots are also occurs in pairs. If is a root of polynomial, then its is also the root of that polynomial, it means number of irrational roots always an even number.
In options A, B and C either complex or irrational roots are odd, which is not true.
Therefore, the correct option is D.
9+5y is the correct answer
Answer:
The answer to your question is 109 feral cats
Step-by-step explanation:
Data
f(x) = 200 (0.904)
This function is an exponential to find the number of feral cats after 6 years, just substitute the number of years (6) in the equation and simplify it.
f(6) = 200 (0.904)⁶
Simplification
f(6) = 200(0.546)
Result
f(6) = 109.15 feral cats ≈ 109
The answer is 4140 becsuse there are 12 inches in a foot and 11 and a half feet is 138 inches which is multiplied by 30 to give 4140
