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:
<h2>y = 9x + 65</h2>Step-by-step explanation:
To find the equation of the line given the slope and a point we use the formula
where
m is the slope
( x1 , y1) is the point
From the question the slope is 8 and the point is ( - 9 , - 7)
Substitute the values into the above formula and solve for the equation
We have
We have the final answer as
<h3>y = 9x + 65</h3>Hope this helps you
