The correct answer is between c and d, i hope this helps
Answer: D
Step-by-step explanation:
(3 + 2i) (3-2i) = 13
We have to find the slope of these lines using the slope formula
<span>slope = (y2 - y1) / (x2 - x1) </span>
<span>Line WX : </span>
<span>(-1,2) x1 = -1 and y1 = 2 </span>
<span>(4,12) x2 = 4 and y2 = 12 </span>
<span>now sub into the slope formula </span>
<span>slope = (12 - 2) / (4 - (-1) </span>
<span>slope = 10/(4 + 1) </span>
<span>slope = 10/5 which reduces to 1/2 </span>
<span>so the slope of line WX = 1/2 </span>
<span>Line YZ : </span>
<span>(5,8) x1 = 5 and y1 = 8 </span>
<span>(-2,-6) x2 = -2 and y2 = -6 </span>
<span>now we sub into slope formula </span>
<span>slope = (-6-8) / (-2-5) </span>
<span>slope = -14/-7 </span>
<span>slope = 1/2 </span>
<span>so the slope in line YZ = 1/2 </span>
<span>Line WX and line YZ are : (D) parallel because the slopes are the same.</span>
Let x be the number of rotations left to run, then
x + 6 ≥ 45
Answer:
D
Step-by-step explanation:
40 / 2 = 20
area = (pi)*r*r
20*20*(PI) = circle area
it's half of the area, so you need to divide it by 2
