Answer:
3xpi/2 is 270 degree counter-clockwise from Ox
That time P(x,y) is (0,-1)
=> x= 0 and y = -1 as you can see in picture.
=> Cos 3pi/2 = x = 0
=> Sin 3pi/2 = y = -1
Step-by-step explanation:
Not so slow.
Answer:
I think 0 -10 or mabe 0,-11
13.63 * 38 = 517.94
671.28 - 517.94 = 153.88
153.88 : 13.63 = 11.25 the number of hours she overworked
I think its 44. The amount of people increase by 12 every time you add more subs. Hope that helps!
Answer:
x= -3+√2 or x= -3-√2 ( answer : A and B )
Step-by-step explanation:
hello :
x²+6x+9 = (x+3)².....identity
x²+6x+9 =2 means : (x+3)²=2
so : (x+3 = √2) or (x+3 = - √2)
so two solutions :
x= -3+√2 or x= -3-√2
