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:
Step-by-step explanation:
Brain correctly use a method of completing the square to solve the equation:
His First Step is to: Take the Constant Term to the Right Hand Side
The Next Step Would be to:
- Divide the Coefficient of x by 2
- Square It
- Add it to both Sides
In this case, the Coefficient of x = 7
- Divided by 2 =
- Squaring It, we have:
It is this number that is added to both sides in the manner below:
V = πr2<span>h
V = 3.14 x 7 x 7 x 10</span><span>
V = </span>1538.6 cubic meters.
Hope i become the brainliest.
The answer is: [C]: " 3 " .

Explanation:
__________________________________
4x - 1 = 2x + 5 ; Solve for "x" ;
__________________________________
Subtract "2x" from each side of the equation; and add "1" to each side of the equation:
___________________________________________________
4x - 1 - 2x + 1 = 2x + 5 - 2x + 1 ;
___________________________________________________
2x = 6 ;
_________________________________
Divide EACH side of the equation by "2" ; to isolate "x" on ONE side of the equation; and to solve for "x" ;
_________________________________
2x / 2 = 6 / 2 ;
_________________________________
x = 3 .

Answer: 16 units
Step-by-step explanation:
Point A and Point B are 5 units apart on the x-axis.
Since this is a rectangle, the opposite side is equivalent.
Point A and Point C are 3 units apart on the y-axis.
Same thing applies for these points.
5+5+3+3=16 units
