Answer:
B
Step-by-step explanation:
Using the exact values
cos150° = - cos30° = -
sin150° = sin30° =
Given
z = 4(cos150° + isin150° ) , substitute values
= 4(- +
i )
= - 2 + 2i , that is
(- 2, 2 ) → B
Answer:
is a polynomial of type binomial and has a degree 6.
Step-by-step explanation:
Given the polynomial expression
Group like terms
Add similar elements: -8c-8c-9c=-25c
Thus, the polynomial is in two variables and contains two, unlike terms. Therefore, it is a 'binomial' with two, unlike terms.
Each term has a degree equal to the sum of the exponents on the variables.
The degree of the polynomial is the greatest of those.
25c has a degree 1
has a degree 6. (adding the exponents of two variables 'c' and 'd').
Thus,
is a polynomial of type binomial and has a degree 6.
