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
12%... (3×4)/(25×4) = 12/100... 12/100 = .12 which is 12%
You need to know the length of two sides and the degree of one angle.
Let
x: amount of pounds of cheese that Bill can buy.
We can write the following inequation for this problem
x <= 1/2
Therefore, Bill could buy up to 1/2 pound of cheese.
answer
1/2 pound of cheese (maximum)
I believe the equation is y = -3x + 0
