z = 3(cos π/2 + i sin π/2) =→

z⁷ =

4 5/10
+6 9/10
10 14/10
simplify it to 11 1/10
ANSWER=11 1/10

Answer: It is 1/12
Step-by-step explanation:
There are a total of 12 cards. If you look at the table, there is only one yellow card that is even. So it is 1/12.
Answer:
3x - y = -7
Step-by-step explanation:
y = mx + b
m = deltay/deltax
m = (10 - 1)/[( 1 - (-2)]
m = 9/3 = 3
y = 3x + b
From (-2 | 1) we see that when x = -2, y = 1
Placing into the equation, in order to find b (y-intercept)
y = 3x + b
1 = 3(-2) + b
b = 7
y = 3x + 7 or 3x - y = -7
